About this game

Assimilation Chess is a chess variant built on familiar chess movement, check, checkmate, castling, en passant, and promotion rules. The twist is that every non-king capture transforms the attacker into the captured piece type while keeping its original color.

A pawn that captures a queen becomes a queen. A queen that captures a pawn becomes a pawn. A knight that captures a rook becomes a rook. Kings still capture as kings.

Play local pass-and-play, learn the transformation rule in the tutorial, test tactics against legal-move bots, and take games online with server-validated moves. Casual and ranked ratings are separate, ranked games require an account, and bot games do not affect player ratings.

Features:

- Standard chess foundation with capture transformation.
- Tutorial lessons for the new rules.
- Local pass-and-play.
- Solo bot play.
- Private games, casual matchmaking, and ranked play.
- Ranked leaderboard, match history, and replay support.
