Single suit modified
Single suit modified is a modification to the single suit, bamboo mahjong game. Instead of just a single suit, honor tiles are added in relation to the number of players: two. This modification is devised by Kyuu and members of the Chicago Area Mahjong Players.
Tile setup
This version takes the number of players into account. The regular four player mahjong game has three suits, four wind types, and three dragon types. Under a similar approach, this two player game uses one suit, two wind types, and one dragon type. With this, the number count is down to 48 tiles.
The wall
Dice procedure
The dice are used for two primary purposes: determining the initial dealer and breaking the wall. To determine the initial dealer, players may either roll for the highest value or simply call based on even-odd.[1] For wall breaks, the dealer makes the roll and breaks according to the dice count starting from the right side of the wall.

Yaku
Given the tile count reduction, the yaku involved is also reduced. Likewise, the yaku values for this version is also modified.
