Dark Crazyhouse 2 is even more dark, than DarkCrazyHouse; you can only drop pieces on 'visible' squares, and you do not know, which squares are empty.
Game rules
The game is played according to the CrazyHouse rules - the pieces are initially set up in standard way, the pieces you capture become yours, and can be dropped on the board, the game ends in checkmate, etc.
Captured pieces can be dropped on any empty square, including checking the King. Pawns cannot be dropped on the 1st or 8th rank, and if a promoted pawn is captured, it reverts back to a pawn.
The board is partially hidden. The following visibility rules are in place:
- all your pieces are visible,
- squares available to your pieces (squares where your pieces can move, or capture) - including attacked enemy pieces, if any - are visible,
- you can see which pieces you have taken (and have at hand),
- you can see which pieces your opponent have taken (and have at hand).
