MergeDrift

Sliding Puzzle is an offline number-merging game built around full-board swipes, careful space management, and fixed challenge runs. Start a classic run to push for a higher score and a larger tile. Slide the board in four directions, merge equal tiles once per move, and use the undo action to recover from a mistake. Challenge levels use fixed start boards and deterministic random sequences. Some levels ask you to reach a target tile, some ask you to keep a corner empty for a fixed number of moves, and others require you to clear blockers before the move limit ends. The app also includes a smaller practice board, local statistics, saved runs, a guide page, and configurable preferences for swipe sensitivity, merge animation, sound feedback, tile texture, and theme. Everything is playable offline with local device storage only.
