About the game
This is not cheating—it's magic!
Senpo Mahjong is a new kind of online riichi mahjong where spells called "Skills" bend the game to your will.See through your opponents' hands. Control your draws. Conjure dora out of thin air and send your score soaring.
On top of raw mahjong skill, every match adds a layer of mind games—when, and which, Skill do you unleash? A battle of wits you'll find nowhere else awaits.
Skill System
- A diverse arsenal of Skills — three schools: Information (peek at opponents' hands), Tile Manipulation (control draws and tiles), and Scoring (boost your points)
- MP management — Skills consume MP that builds up during the match. Timing your trump card decides the game
- Cut-in animations — every Skill activation is revealed to the whole table with flashy effects. Whoever masters the exchange of Skills takes the win
Game Modes
- Online matches — real-time 4-player and 3-player mahjong
- Ranked — climb the ladder of treasures from novice all the way to the top rank: Senpo King
- Private rooms — create a room and play with friends only
- CPU matches — hone your Skills solo at your own pace
- Spectating & replays — watch other tables, or review your own games move by move
