On a 9×9 minefield, tap to reveal safe cells and long-press to flag mines. Each valid move saves a board snapshot. You get up to 3 Rewinds per game to undo your last move, or spend one Rewind on Foresight to flash one safe cell (green) and one mine (red). You have 180 seconds to reveal every non-mine cell to win; hitting a mine or running out of time loses. Reset starts a new board, Exit returns home, and your best score is saved locally with Room.
