#10. yeah, not possible especially due to chess.js. Basically, anything that changes piece movement (like being able to drop a piece, or changing the behaviour of some pieces) or how moves are made (1 at a time, so no Marsellais chess) is not possible with chess.js, which interprets moves for lichess. And that category includes crazyhouse, because there is no way to represent a piece being dropped onto the board.

people should join it is very nice i've tryed it! but you need all the players to be registered to play rated.
