📝 About this app
Mahjong Solitaire‑7 is a collection of engaging puzzles based on the classic rules of mahjong solitaire. Your goal is to clear the board by matching pairs of identical tiles. Some tiles may be considered matching even if they look different, which adds an extra layer of challenge and variety.
To remove a tile, it must be free — not blocked by other tiles on the left, right, or above. Tap two identical free tiles and they will disappear from the board.
🔹 Game Features
🀄 35 unique layouts with different levels of difficulty
