🎯 GOAL: Checkmate the rival king — trap it so it cannot escape capture. Beat a rival to unlock the next and open a 🎁 Royal Chest!
👆 CONTROLS: Tap one of your (white) pieces — green dots show every legal move. Tap a dot to move. 💡 Hint and ↩ Undo: 3 each per game.
♟️ SPECIAL RULES (all traditional): Castling — king & rook swap safety in one move (not out of/through check). En passant — a pawn that just jumped 2 squares can be captured as if it moved 1. Promotion — a pawn reaching the far end becomes any piece (usually a Queen!). Stalemate = draw.
