Space mahjong
Space mahjong is a modified set of rules to mahjong. Here, the limitations on terminal tiles and honor tile are removed. Normally, the 1-9 scale ends with 1 and 9 as terminals. In this set of rules, the number sequence is given the wrap around effect when it comes to the formation of tile groupings.
Tile groupings
Due to the wrap around effect, the terminal tiles operate just like any other numbered tile.
