About Chess AI
Chess AI is a relaxed, good-looking chess board with a wooden frame and smooth sliding pieces. Tap a piece and every legal square lights up, while tiny icons on each tile show which pieces can reach it, so it is easy to see threats and plan captures at a glance.
The rules are real chess: moves that would leave your king in check are blocked, and castling, en passant and pawn promotion to a queen all work. By default you play White against a computer opponent that chooses random legal moves, which makes it a friendly sparring partner rather than a grandmaster.
The Auto switches let the computer play either side, so you can hand both colours to a friend on the same device or sit back and watch a bot-versus-bot game at up to 20 moves per second. It is ideal for beginners learning how pieces move and for anyone who wants a quick, casual game.
How to play
You play White and move first: tap one of your pieces to see its legal moves, then tap a highlighted square to move or capture. Black answers automatically when its Auto switch is on. Checkmate the enemy king to win; if a side has no legal moves and is not in check, the game is a stalemate.

Tips
- Watch the small piece icons on each square: they show which pieces from both sides can move to or capture there.
- The computer moves at random, so set simple traps and it will often walk right into them.
- Turn off Black's Auto switch to play a friend on the same screen, taking turns with the pieces.
- Switch both Auto kings on and pick 20 APS to watch a full random game play out in seconds.

FAQ
Is Chess AI free to play?
Yes. It is completely free and runs in your browser with no download or sign-up.
Can I play on a phone or tablet?
Yes. Tap a piece and then a highlighted square to move; the board scales to fit phone and tablet screens.
How strong is the computer opponent?
Not strong at all: it picks a random legal move each turn, so it is best for learning and casual games rather than serious training.
