Welcome to the twisted world of Anti Chess.

Anti Chess is one of the most popular variant of chess. The objective of the game is for each player to lose all their pieces.
Play this free fun game of Anti-chess on your iPhone, iPad, or iPod.

How to play?
The aim of the Anti Chess is to sacrifice your pieces. The game is setup on a chess board in the same order as traditional chess and plays the same way too, but with a few interesting rules :

1. When a player's piece is in a position to kill the opponents' piece, the player has to commit that move.

2. The game is over when one of the player has all of their pieces killed
The game is not over if the King is killed. There is no checkmate in Anti Chess

3. There is no castling

4. When a pawn reaches the end of the board, it gets promoted to a Queen

5. If there is a situation where no player can make any more moves, the player with the lesser number of chess pieces wins the game.


This game supports one player, where you play against a computer AI. It also supports two players (local PVP) mode.

Interesting game! :D
Perhaps it could use some additional sounds/voices made by the characters when doing specific action to add a bit more comedy to this.

Good job!

Weird game

This is very original but even on Master the game is way too easy. What kind of AI are you using? it is rather fast but very myopic.

Message from our dear fried @ZenCoder, the game programmer -
"We use a node based decision tree of every possibility using a breadth first approach with some optimizations. So essentially, the AI looks at all its possible moves, ranks them. Then looks for each possible response that the human player can do for each of those moves, ranks them. And so on, down the child nodes of the tree.

For the Master level, it does 4 iterations of this. Unfortunately, unlike Chess, the simplistic design of Anti-Chess and its snowbally nature, makes creating a challenging AI almost impossible. If you play the game enough or get good enough at it, you will realize that unlike Chess, the depth of strategy is actually pretty low. We had thought of changing the design of the game to add more strategy but at that point it would take away from being familiar to players who know to play Chess.

On a side note, its way more fun to play vs a good player in Local Player mode than AI, if you get a chance :)"
