Real or AI?
Ten text pairs and ten image pairs: one made by a human, one by an AI. Learners decide, say how sure they are and check the source. Being confidently wrong costs points.
Learning games about AI
Free to play. Free to fail. Free to learn.
In a game, a mistake costs nothing: you just press “Again”. That makes it the right place to find out what AI can do and where it fails. Two browser games in English from the LKAI AI series, ready for class.

FAQ
Frequently asked questions
How do I buy, and do I get an invoice?
You order through Digistore24. Digistore24 is the seller of record: it takes the payment (for example PayPal, card or direct debit), issues an invoice showing VAT and emails the download link right away. Schools can also order against an invoice.
What is the difference between a single licence and a school licence?
A single licence covers one teacher and all of their classes, even across several schools. A school licence covers the games for every teacher at one school, as an annual or a perpetual licence, and is handled by quote and invoice.
Which devices do the games run on?
Any current browser: Chrome, Edge, Firefox and Safari, on laptops, Chromebooks and tablets.
Do the games need an internet connection?
No. Each game is a single HTML file, runs offline and loads nothing from the internet, for example from a USB stick or your learning platform.
May I upload the games to Moodle?
Yes. You can share the games with your own classes through a password-protected learning platform such as Moodle. Publishing them on openly accessible websites is not allowed.
Is any student data stored?
There are no accounts and no sign-in, and the games send nothing to a server. Progress is kept only in the browser on each device. Where a game includes an evaluation, learners pass their result to the teacher as a code.
What comes with a game?
The game in English and German as HTML files, plus a worksheet and a teacher's guide with learning goals, lesson plan and solutions as editable Word files. Worksheets and guides are currently in German. Updates are free.
Who are the games for?
Real or AI? works in any type of school from year 8 (age 13+). Prompt Hackers is aimed at older learners and business programmes. The curriculum notes on each product page are a guide; please check them against your own syllabus.
Failing allowed.In games, losing is normal.Nobody is ashamed of a game over.You just press “Again”.
About LKAI
LKAI stands for Leo Köhler and artificial intelligence. A private project, built in his spare time out of two passions: playing and building.
Leo Köhler studied business administration and economics and teaches business studies. In his free time he is a keen board gamer. He has been building digital tools for years, including at his own start-up for smartphone apps.
With the arrival of new AI tools he saw the chance to bring both together for the classroom: simulations that run without a server and without AI in the background, yet still demand real decisions. Every game comes with classroom materials.
LKAI is a private project and not an offer of any school or education authority.
