Chess is the classic game for thinking – and a good antidote to the reflex of always reacting at once. In the little collection of games among my tools there is 3D chess against the computer, in its own spatial presentation. It runs in your browser and transmits nothing.
At a glance
- Its own 3D presentation (WebGL) with illuminated pieces, cast shadows and a freely rotatable camera.
- Five difficulty levels from beginner to hard – its own game engine, no third-party service.
- All the rules: castling, en passant and promotion included.
- Move hints, move list and take back – good for practising.
- Free and local: free of charge, free software, nothing leaves your browser.
How to play
You play with white against the computer. The possible moves of a piece are shown; the move list keeps track of the game in German notation. Whoever has misjudged something takes the last move back with "take back". The camera can be rotated around the board to view the position from different angles.
In short
A complete chess game with its own presentation and its own engine, free of charge as free software under the GPL: Open 3D chess. If you would like to shape your tools and processes in your company so that they serve people, get in touch with me for a free initial consultation.
3D chess is a game for entertainment and practice; the computer engine makes no claim to tournament strength.
