Zen Mahjong: Classic Tiles

- Match identical free tiles to remove them; a tile is free if nothing is on top and at least one side is open. - Tap a tile to select it, then tap a matching tile to clear the pair; plan moves to avoid blocking yourself. - Use Hint to spotlight a possible match, Undo to take back a move, and Shuffle when no moves remain. - Build streaks by clearing pairs in succession to earn combo multipliers and higher scores. - Choose a mode: Zen for no timer, Classic for a relaxed challenge, or Daily Challenges for fresh puzzles and rewards. - Clear all tiles to finish the board and earn stars that unlock new tile sets and backgrounds.
