A quick guide to Reveal Chess
Read the Reveal Chess rulesWhat is Reveal Chess?
Reveal Chess is a ChessPlayX hidden-information variant on an 8×8 board. Kings stay visible; other pieces begin covered and reveal after their first move. The starting role and revealed identity can differ. Read this variant's rules before playing.
Can I choose what a covered piece becomes in Reveal Chess?
No. When a covered piece makes its first move, its role is drawn at random from your remaining pool, in proportion to the pieces left. At the start the Queen chance is 1/15 and the Pawn chance is 8/15. You can see the pool but not pick from it.
Does capturing a covered piece reveal it?
No. A covered piece captured before its first move stays secret, and its owner's pool does not change. Those unused pool entries can never return to the board, so the pool total equals covered pieces on the board plus covered pieces already captured.
Does revealing a piece reset the 50-move count?
Yes. A reveal resets the count, just like a capture or a pawn move. You may claim a draw after threefold repetition or 50 moves by each side without any of them; fivefold repetition or 75 such moves by each side draws automatically.
