      <title>I. INTRODUCTION</title>
      <p>
        A variety of sources claim that English is the most popular
foreign language to learn [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ], [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]. A couple of decades ago,
English, as well as other foreign languages, was mostly taught
and learned in classroom-based formal education. However,
with the rise of mobile technology, vast opportunities for
nonformal language learning emerged. People are no longer limited
to learning at a specific place at a specific time. In other words,
they have access to ubiquitous learning [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]. It can be suggested
that when it comes to ubiquitous foreign language learning, it
was especially boosted by free mobile applications. There are
hundreds of free or semi-free apps that address acquiring
holistic foreign language skills. Some of them, e.g. Duolingo,
Mindsnacks, and Memrise, feature simultaneous learning and
practicing of language skills via gamified environments. That
is, there are different game-like elements, such as levels, points,
badges, and likewise. The aforementioned together with the
gains of learning a language which is the third major language
in terms of the number of native speakers, English [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ], are the
reason why these apps are becoming more and more popular.
      </p>
      <p>
        In the light of the above, it is evident that formal education
must keep up with the changing preferences and needs of the
contemporary ubiquitous learner. Therefore, foreign language
instructors strive to employ Information and communication
technology (ICT) to make the teaching/learning process more
attractive, fun, and at the same time efficient. Foreign language
teachers either come up with innovative ways to exploit already
existing ICT resources (e.g. social media [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ], wiki [6], vine [7],
or e-books [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ]) or develop their own. In the academic literature,
one can notice an increasing number of publications on such
technology-enhanced language instruction. Recent studies
indicate a variety of potential or already proven benefits of
game-based foreign language learning, including increasing
students’ involvement, motivation and attentiveness to detail
[
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]. The aim of the present paper is to provide an overview of
the latest papers on game-based foreign language instruction
that report the results of the learning outcomes when the tool
that is used for instruction was developed by the instructors
themselves.

        <p>
          As the current paper gives a theoretical overview of the
newest research trends in a specific area, gamified EFL
instruction, the only data source is research papers. They were
selected by drawing on the methodology proposed by [
          <xref ref-type="bibr" rid="ref10">10</xref>
          ]. The
paper selection was carried out in several stages. Firstly, the
available scientific journals from the top 20 Google Scholar
scientific journals on educational technology1 were inspected
by looking for the keyword ‘language learning’. Then, to
ensure that none of the potentially relevant papers remain
unnoticed, the researcher went through all the issues of the
aforementioned journals (published in 2017) manually. Later,
the selected papers were assessed in terms of their suitability
for the present survey. Some papers were deemed unfit for the
purpose because they (a) do not focus on gamified EFL
teaching / learning, (b) do not focus on teaching skills, thus
were rejected.

        <title>A. EFL Instruction</title>
        <p>
          To begin with, EFL stands for English as a foreign
language. When it comes to foreign language teaching and
learning, two main terms are used to define the phenomena. As
Moeller and Catalano [
          <xref ref-type="bibr" rid="ref11">11</xref>
          ] explain, ‘foreign language teaching
and learning’ refers to when students are being taught a
language other than their mother tongue in a different country
than the language is typically spoken. Another term is ‘second
language acquisition’, which describes learning a non-native
language while living in the environment where it is commonly
spoken [
          <xref ref-type="bibr" rid="ref11">11</xref>
          ]. Scholars indicate that regardless whether
individuals are taught a foreign or second language, the
traditional teaching paradigm has shifted from teacher-centered
to learner-centered language teaching [
          <xref ref-type="bibr" rid="ref11">11</xref>
          ], [
          <xref ref-type="bibr" rid="ref12">12</xref>
          ]. It means that
the teacher should establish rapport with the students and take
into consideration their learning styles, needs, and preferences
[
          <xref ref-type="bibr" rid="ref12">12</xref>
          ].
        </p>
        <p>
          In the times when technology is omni-present, it does not
make much sense to be still using the old ways of giving
instruction, especially when it comes to foreign languages.
Nowadays, the majority of students own a mobile device or can
be provided with one (for educational purposes) by their
educational institution. Despite that, some scholars (esp. those
from Taiwan, e.g. [
          <xref ref-type="bibr" rid="ref13">13</xref>
          ], [
          <xref ref-type="bibr" rid="ref9">9</xref>
          ]) emphasize that some foreign
languages, especially English, are still taught by relying on the
archaic paper- and memorization-based tasks [
          <xref ref-type="bibr" rid="ref9">9</xref>
          ]. Such
teaching style does not comply with the new educational
paradigm. Nor does this type of instruction provide
authenticity, which is important in foreign language
teaching/learning [
          <xref ref-type="bibr" rid="ref13">13</xref>
          ], [
          <xref ref-type="bibr" rid="ref14">14</xref>
          ]. More technology-oriented teachers
know that it is exactly where gamified learning environments
can come in handy.

        <title>B. Gamified Foreign Language Instruction</title>
        <p>
          Almost a decade ago, in 2009, Thrilling and Fadel claimed
that the available digital tools help to develop the key “21st
century skills: critical thinking, problem-solving, creativity,
innovation, media literacy, ICT literacy, flexibility, initiative,
and self-direction” [
          <xref ref-type="bibr" rid="ref15">15</xref>
          ]. It can be argued that all of these skills
should be also transferred into the context of learning foreign
languages. There are teachers around the world who are trying
to achieve exactly the aforementioned. Not only do they
experiment on using diverse teaching methods (e.g.
problembased learning [
          <xref ref-type="bibr" rid="ref16">16</xref>
          ], flipped classroom [
          <xref ref-type="bibr" rid="ref17">17</xref>
          ], or language
immersion [
          <xref ref-type="bibr" rid="ref18">18</xref>
          ]), but they also devise their own teaching
materials and those who are more tech-savvy even develop
their own educational games.
        </p>
        <p>
          Recently, gamified language instruction has become very
popular. The benefits as well as challenges of educational
games have been discussed and reported upon by quite a
number of scholars globally (e.g. [
          <xref ref-type="bibr" rid="ref19">19</xref>
          ], [
          <xref ref-type="bibr" rid="ref20">20</xref>
          ], [
          <xref ref-type="bibr" rid="ref21">21</xref>
          ]). To prove
that the outcomes of gamified learning are more satisfactory
than those achieved by the traditional means, experimental
studies are conducted and the two teaching/learning styles are
compared. The latest studies usually note that when playing
educational games, students actually acquire more knowledge
and improve their language skills (e.g. those of listening and
speaking) [
          <xref ref-type="bibr" rid="ref15">15</xref>
          ], [
          <xref ref-type="bibr" rid="ref22">22</xref>
          ], [
          <xref ref-type="bibr" rid="ref23">23</xref>
          ]). Some studies, on the other hand,
reveal that the only significant learning outcome result is when
the lower-achieving students are compared, which means that
there is no great difference between the intake of more
advanced learners [
          <xref ref-type="bibr" rid="ref13">13</xref>
          ]. Ideally, gamified learning should be
beneficial to each and every student.
        </p>
        <p>
          Nonetheless, the abovementioned research conclusions
should not be taken for granted. There is a lack of longitudinal
studies that indicate the long-term retention results of learning
via gamified educational environments [
          <xref ref-type="bibr" rid="ref24">24</xref>
          ]. To prove or
disclaim the actual educational potential of gamified EFL
instruction, more scholarly effort needs to be invested in
carrying out longitudinal studies on the long-term effects of
relying on educational games to learn English (as well as any
other foreign languages).

      <title>III. THE IDENTIFIED EDUCATIONAL GAMES</title>
      <p>This section contains a brief overview of the educational
games that were identified after carrying out a survey of the
most recent publications on technology-enhanced EFL
instruction.</p>
      <sec id="sec-4-1">
        <title>A. The Conference Interpreter [25]</title>
        <p>The game was developed by the authors of the paper back
in 2013. The authors note that before applying the game in an
actual teaching/learning environment, in total 17 versions of the
game were piloted and revised after receiving feedback from
the players. The intended audience is university students. The
educational game is in essence a simulator of a conference, thus
students have to simultaneously translate, for which they need
to know and use appropriate lexis. The simulation is in English,
while the target language is Spanish. Students are then exposed
to multiple-questions-type exercises in which they need to
choose the appropriate option (see Fig. 1b). The purpose of the
game is to increase the learners’ vocabulary and a variety of
skills needed for an interpreter. In addition to the educational
content and instant feedback, the game also features a level and
reward system and enables collecting scores and power-ups.</p>
        <p>To test the effectiveness of the game, an experiment was
conducted. One group of students played the game without
any teacher intervention (experimental group). Another group
got to study from a booklet with the same contents as in the
game (control group). The students were also asked to
complete a pre-test, post-test, and delayed test. Statistically
processed data reveal that even though students in the
experimental group had no help from the instructor, they
learned the target vocabulary because they played the game.
Moreover, their learning results were better than those of the
students in the control group. However, when their test results
were compared six weeks after the experiment, there were no
significant differences in students’ knowledge of lexis.

        <title>B. Near East University Children’s Story Teller (NEUCST)[26]</title>
        <p>The Android mobile application was developed by the
authors. As it is based on children’s stories, it is aimed at
young students (more precisely, 12-13 years old). Some
features of the application (e.g. music) are based on previous
studies that reveal what aspects make the learning process not
only successful, but enjoyable as well. The authors indicate
that the game includes a unique component, which is
speechto-text application that allows to listen to the text being read as
one is looking at it on the screen. The learner also gets instant
feedback. The simplicity and colourful imagery of the game
(see Fig. 2) addresses vocabulary acquisition as well as
comprehension, pronunciation and listening skills. The game
has an in-built testing option, too.</p>
        <p>An experiment was conducted to check whether the
students in the experimental group would achieve the target
results without any teacher intervention, by solely relying on
playing the educational game. The students in the control
group read a traditional children’s storybook with the same
contents as in NEU-CST. The students in the both groups also
completed a pre- and post-test. The results reveal that there is a
statistically significant difference when it comes to the
aforementioned students’ achievement. The experimental
group shows better learning outcomes of vocabulary,
comprehension, pronunciation, and listening.</p>
      </sec>
      <sec id="sec-4-3">
        <title>C. Problem-based English listening game [9]</title>
        <p>The authors developed the game. They do not indicate at
what specific age category the game is aimed, but in this case,
it was played by ninth graders. The purpose of the game is to
enable the students to practice, enhance or develop their
listening skills and to reduce their language anxiety. They
supposedly do so while following a storyline of a wizardry
school from which they will eventually graduate provided they
perform the necessary tasks and successfully overcome some
challenges on their way. The game is built on three databases,
namely those of materials, gaming elements, and students’
profile. The first database is comprised of resources (i.e.
listening tasks, a vocabulary, and extra materials) provided by
an expert language instructor. The second database holds a
variety of game components, such as battles and weapons as
well as treasures and bonus rewards. The third database
collected information on the learners’ status and learning
behaviours. The listening game has different difficulty levels
(see Fig. 3), or phases, to achieve which, students need to
complete various listening tasks.</p>
        <p>The authors compared the problem-based game to
conventional technology-enhanced teaching. The experimental
group was exposed to the former, and the control group to the
latter. The both groups took a pre- and post-test. The statistical
analysis shows that students benefited more from playing the
problem-based game than from the other type of instruction.</p>
      </sec>
      <sec id="sec-4-4">
        <title>D. Task-based learning AR educational game and Selfdirected learning AR educational game [27]</title>
        <p>Both games were developed by the authors with a specific
audience, third-graders, as well as different learning styles in
mind. The AR educational games run on Tablet PC. The goal
of the games is to expand learners’ vocabulary and increase
their spelling skills. To investigate and compare different
learning approaches, one game is built upon the self-directed
learning style, whereas another game is based on task-based
learning. The former AR educational game allows students to
regulate their own learning by giving them the opportunity to
choose the order of the learning targets as they wish. The latter
AR educational game gave no freedom for the students to
select the sequence of the tasks, and everything was controlled
by the system. Another difference between the two games is
that in the first version, students can re-choose the target,
whereas in the second game they can only proceed to the next
step if they have successfully fulfilled the previous one.
Despite the aforementioned differences, the games have some
features that they share; for example, they contain the same
vocabulary resources and have seven situational stations.
Every learning target is superseded by a vocabulary test. As
children cannot type well enough yet and the screen is rather
small, the tests rely on dragging the letters with fingers to
make up the words required.</p>
        <p>The two approaches to learning were compared. Students
took pre- and post-tests. Interestingly enough, after applying
statistical measures to see whether there is any significant
difference between the results of the two groups, none were
found. In other words, all students performed equally well.</p>
      </sec>
      <sec id="sec-4-5">
        <title>E. Happy English Learning System [28]</title>
        <p>The downloadable off-line game is based on Monopoly and
Chance and was designed for mobile devices. It incorporates
course materials and assignments with gaming elements. To
develop the game, the authors combined game science and
mobile computing. The game was played by tenth-graders. In
the game, the learner can choose an appropriate level of
difficulty and, to proceed with the game, has to answer the
questions that are based on the learning objectives. In addition,
students have the chance to discuss the materials and the game
itself on Facebook. The game is built to be beneficial to the
instructor as well. That is, the teacher can manage the
resources that are present on the game and see the discussions
on the Facebook forum.</p>
        <p>The effectiveness of the game was experimentally tested.
There was an experimental and a control group, both of whom
also took a pre- and post-test. After applying statistical
analysis to their dataset, the authors conclude that the group
that played the educational game achieved better results.</p>

        <title>Integrated Learning in Opensimulator Project] [15]</title>
        <p>The authors report that it took a total of 160 hours to
develop the game. It was then piloted and afterwards
improved. The target age group is not specified, but the
educational game was employed to teach six-graders. The aim
of the game is to teach the learners lexis related to Geography,
thus they get to control avatars that are visiting a virtual island
and exchanging conversations in English. In the game,
students traverse the island and get information about the
target vocabulary on the way, at sign-posts and media corners
which were specifically designed for that function. The latter
two elements of the game contain such resources as videos and
presentations. Students can interact with them by pausing,
rewinding, and likewise. The game also suggests benefits for
the instructor as it is based on ready-made scripts. This means
that s/he need not invest too much time in scripting and
programming. The authors claim that once the script is
developed, it does not require too much effort to adapt it
according to other lesson plans.</p>
        <p>Fig. 6. The interface of OpenSimulator Project-CLILiOP</p>
        <p>The authors investigated the potency of the game. In total,
there were three groups of students that took part in the
experiment. The first one was control/conventional, the second
was taught by using conventional CLIL, and the third one was
exposed to CLILiOP. The members of each group got to take
pre- or post-tests. The results indicate that those students who
had the latter method included in their learning process
achieved more than two times greater results than the control
group.</p>

    </sec>
    <sec id="sec-5">
      <title>IV. DISCUSSION</title>
      <p>
        Almost all the previously described educational games
(except [
        <xref ref-type="bibr" rid="ref25">25</xref>
        ]) are used as a supplement for at least somewhat
traditional teaching/learning. It is not specified whether
instructors employ any additional innovative strategies in
teaching EFL. The latter is important because it may effect
students’ cognitive abilities, motivation, or other factors that
play a role in language learning.
      </p>
      <p>
        The greatest drawback of the surveyed studies is reliability.
The experiments were carried out with small samples in a
short period of time. Only one paper [
        <xref ref-type="bibr" rid="ref25">25</xref>
        ] employed a delayed
test, and its results suggests that with time, the better learning
outcome achieved by playing an educational game, plunge to
the same level of those who received traditional EFL
instruction. It is of paramount importance to investigate the
long-term results of playing educational games, otherwise
their real educational potential remains undisclosed. That is
not to say that carrying out long-term studies of this kind
would be easy. The same instructor does not necessarily teach
the same students and it would be hard to claim that students’
knowledge was not influenced by other sources or factors (e.g.
media, films, music, or even other games).
      </p>
      <p>
        The authors (developers of the educational games) admit
that it is time-consuming to develop and launch the games.
Nonetheless, the way some of them designed their games
provides a good framework that can be easily adapted to a
variety of different topics (e.g. [
        <xref ref-type="bibr" rid="ref15">15</xref>
        ], [
        <xref ref-type="bibr" rid="ref28">28</xref>
        ]). It can be suggested
that the games could also be adapted to teaching languages
other than English as well.
      </p>
      <p>By looking at the screenshots of the game interfaces, one
can see that some of the games are more sophisticated than
others. The quality of the graphics and game elements may
have an effect on how well the game performs its desired
function – conveying educational content that one is supposed
to comprehend and consequently learn. None of the studies
address this issue, but future studies should take this concern
into account.</p>
      <p>
        Despite the aforementioned short-comings, the results of
the studies can be regarded as promising to at least some
extent because the educational games are compared to
traditional teaching/learning materials. That is, authors
conduct experiments on two (in one case, three [
        <xref ref-type="bibr" rid="ref15">15</xref>
        ]) groups.
One is exposed to experimental conditions (i.e. play the
game), the other works on the same materials but in a more
traditional way (i.e. students do the exercises and tests on
paper).
      </p>
      <p>In general, it can be stated that the six educational games
comply with the student-centered educational paradigm. The
amount of instruction is reduced and there is more emphasis
on self-regulated learning, thus empowering the learner to
control his/her learning process. More importantly, by learning
EFL via educational games, students also acquire or at least
improve the earlier mentioned 21st century skills (e.g.
problem-solving, creativity, and ICT literacy).</p>

      <title>V. CONCLUSION</title>
      <p>This paper provided an overview of six educational games
that were developed in order to teach EFL. All the six games
were developed by EFL instructors themselves with the
purpose to increase their students’ language skills. The games
address holistic language skills and are mostlly directed at the
youngest segment of EFL learners. The effectiveness of the
educational games were tested experimentally. Five out of six
games result in significantly greater learning outcomes when
compared to the results of the control groups. Nevertheless,
the results should not be taken for granted as the studies only
reveal short-term results. Future studies could address this
issue and reveal the potential of technology-enhanced EFL
learning in the long run.</p>
