Getting Started with chessperiment

Stockfish

chessperiment can use Stockfish as an engine. Stockfish allows:

  • playing against an AI
  • position analysis
  • comparing different boards and rule sets

Depending on the complexity of the rules, engine behavior may vary.

Room Code

A room code lets you share games easily: other players can join directly, making it ideal for private matches or testing.

The code ensures that all players use the same rules, boards, and pieces.

Chess rules

chessperiment is conceptually based on chess, but extends it:

  • classical rules only apply if you define them
  • deviations are explicitly allowed
  • custom rule sets override standard chess

The system is rule-driven: “chess” is not the default — your configuration is.
