4 in 1 (4B-003) — About this game
4B-003 offers Taiwan, Japan and Hong Kong mahjong alongside Store Tris 2. The mahjong choices ask you to build a useful hand while deciding which tile can safely be discarded; changing the regional game changes the rules you should read before chasing a familiar pattern. Store Tris 2 moves the attention to falling shapes, including pieces less regular than the ones a simple straight well suggests. Keep space for the next placement and choose between a patient hand of tiles and the faster pressure of the block field.
