This tile-matching game has been around way longer than the personal computer – but it’s only during the digital age that it’s become a global hit. In this version of the game, you need to remove tiles from the board, two by two. Only the ‘free’ tiles at the edge of a layer can be matched, and if they’re partially covered, they’re not free! In Mahjong Master 2, you complete a series of boards of varying complexity, starting with the simplest ones. If you're stuck, wait a moment and you’ll get a hint in the form of two flashing tiles.
