Game rules

The rules of the game are implemented in pure Dart. The package that holds implementation is insanichess and its implementation is in packages/insanichess.

The game rules are pretty simple. All pieces move the same as their chess siblings. The only difference in game rules apart from chess are the following:

• Pawns can always move only by one square (even from starting position) and can move diagonally without capturing a piece.
• There is no castling. Your king must stand his ground!
• There is no concept of stalemate or mate. To win a game, you must capture opponent's king.
• The game can result in draw if and only if the players agree to a draw.

Repository structure

Insanichess repository consists of three major parts:

• app is a Flutter project containing client side code (mobile and web app);
• server is a pure Dart project containing server side code;
• packages contains three Dart packages: insanichess that holds implementation of game rules, insanichess_engine that holds implementation of Insanichess evaluation engine, and insanichess_sdk that extends insanichess package with functionality that both client and server applications need.
