A new game, free to play. No ads, no subscriptions.
From a simple social media post that introduced a simple game to play on a 4x4 grid with a few chess pieces, I got the inspiration to make this mobile game: Tic-Chess-Toe.
It combines the simplicity of chess with the depth of tic-tac-toe: place your pieces, move like a chess master, and get four in a row before your opponent does!

How to play
- Take turns placing your chess pieces on the board.
- After 3 turns, you can start moving them like in chess.
- Captured pieces? No problem, just put them back on the board next turn!
- When a pawn reaches the end, it doesn't promote to queen. Instead, it changes direction in the next turn.
- First to get four in a row wins!
Features
- Play against the AI with 3 difficulty levels.
- No ads, no purchases, just pure, uninterrupted gameplay.
- Available on Android, iOS, Wear OS, and on MacOS.

But why?
This is such a simple game mechanic, that I decided to use it as an excuse to play around with Kotlin Multiplatform. Plus, I have a fascination for Mini-Max algorithms, which, “back in my day”, carried the label AI. I’ve made a far more optimized algorithm for a chess engine once, but for Tic-Chess-Toe I was able to create a minimax that thinks 4 moves ahead, within seconds, even on a smartwatch. Which, as it turns out, is enough to beat me at the game 100% of the time.

Roadmap
Sorry, this is it: a free game, no ads, no subscriptions, no tracking. There are some improvements I have in minds that will probably follow:
- Tablet layout (it works on iPad, it just looks like I haven't put time into supporting it, which is exactly the case)
- Support web and desktop. The iOS app is available in the Appstore for Mac, but with a basis in KMP, supporting more platforms is possible.
I hope you enjoy this game! If you do, consider buying me a coffee or something?
