How does your game play?Every move kept551,084 games played
Send the rulebook. Bots play it thousands of times and show you what they found, in plain words, before your first playtest. What to change is yours to decide.
If you want, the bots also tune its numbers a little after each round and play again, iterating toward balance.
First, you send the rulebook.

Six things the Lab measures
The Lab measures; you decide. It shows how your game behaves over thousands of plays, never whether it is fun: that is for you and your players.
- A seat that wins too often
- Whether going first, or sitting anywhere, decides the game.
- No real decisions
- Turns where only one move is legal, or every move leads to the same place.
- One move that is always right
- A strategy that beats every other, so players stop thinking.
- Games that never end
- Loops and stalemates the rules do not close.
- Gaps in the rules
- Situations the rulebook does not cover, found when a bot reaches them.
- How much skill decides
- Better bots against weaker ones: does skill matter, and by how much.
Screen a game you know, live
The bots run on Kheeladi’s computer at the booth. A screen plays a quarter of a full test: enough to catch the big breaks in seconds.

Pick a game to see its screen at once, then screen it live if you like: the Lab’s bots play it hundreds of times at every player count and say whether it breaks.
Test your game.
You get a private link at once, and you can follow every step there as the Lab works.
Your files stay yours
Uploads go to a private store, never to a public page or a code repository. AI models read your rulebook only to write the game as code. Your results are on your private link; we publish nothing without asking.
What a test cannot tell you
Bots are not people. They measure whether a game holds together: fairness, real choices, endings, skill. Whether it is fun, funny or beautiful is for your playtesters.
