Based on an idea my father had, where pieces change type after they moved. This game uses that idea but it is a different game.



(The original setup for this game omitted the "P" (pawns) but I then added the pawns later. In my opinion the variant with pawns is better)


  • K=King: Moves 1 space any direction orthogonal or diagonal, like the king in chess. Rule of check/mate doesn't apply (and there is no castling either). After it moves, you may let it stay as a king, or change it into a rook or knight or bishop (your choice).
  • P=Pawn: Move like the pawn in chess, but no initial double-move. Promotes to a rook, knight, or bishop.
  • R=Rook: Move like rook in chess. After it moves, you must change it into a knight or bishop.
  • N=Knight: Move like knight in chess. After it moves, you must change it into a rook or bishop.
  • B=Bishop: Move like bishop in chess. After it moves, you must change it into a knight or rook.


The rules for who wins are:
  1. Any player with no kings loses.
  2. Any player with no legal moves loses.
  3. Any player who causes a repeated position 3 times loses.
  4. Any player who captures 5 opponent kings wins (doesn't count if the kings changed to different kind of pieces before they are captured).
