"Checkmate Rewind" Game

Every case begins at the finish line: the chess game is already over, and the final position is your only clue. Wind the moves back one at a time — bring captured pieces back to life, undo castling, en passant and promotions — and rebuild the starting position using exactly the number of moves the case allows. Master the backwards moves in 8 short lessons, then crack 55 handcrafted cases, from quick blunders to famous opening traps. A fresh case every day comes from real Lichess games.
