About this game

Chess Master is a complete chess game for phone and desktop with every rule of the game in place. Castling, en passant, promotion with a piece picker, the fifty move rule and threefold repetition all work exactly as they do over a real board. You can play against the computer on three difficulty levels, from a forgiving beginner that blunders on purpose to a searching engine that punishes loose play, or pass the device and play a friend in two player mode. Tap a piece to see every legal destination highlighted, tap again to move. An undo button steps back whole turns, a hint button asks the engine for its best idea, captured pieces line up at the top and the move list writes standard algebraic notation as you play. Check and checkmate are announced, stalemate and material draws are detected, and your best score is saved on your device.

How to play

Tap one of your pieces, then tap a highlighted square to move. Use Undo to step back and Hint to ask the engine. Choose a difficulty or two player mode on the title screen.

Tips & Tricks

  • Control the centre with a pawn or two before developing knights and bishops.
  • Castle early. A king in the corner is very hard to attack in the opening.
  • Every move ask one question: what does this leave undefended.
  • In the endgame walk your king toward the action. It is a fighting piece, not a hostage.

Frequently asked questions

Does the game include castling and en passant?

Yes. Every rule is implemented, including both castling sides with their full legality checks, en passant captures, promotion with a choice of piece, the fifty move rule and threefold repetition.

How strong is the computer?

Easy plays quickly and makes human style mistakes, Medium searches a couple of moves ahead, and Hard searches deeper with a sharper evaluation. Hard thinks for a moment on each move, which is normal.

Can I play against another person?

Yes. Choose Two Players on the title screen and the board passes between moves on one device, with no engine involved.

Where is my best score saved?

On your device in the browser. Beating the computer on a higher difficulty scores more, and finishing quickly adds a bonus. Nothing is uploaded anywhere.
