Description
Turn every draw into a better discard decision.
“Mahjong Solo Issou” is a solo riichi mahjong training app designed to improve tile efficiency and offensive decision-making.
Draw tiles automatically, choose what to discard each turn, and work your way toward tenpai. Track changes in shanten and ukeire, then compare your choices with recommended discards based on win probability and expected points.
Build stronger judgment through practice—not just intuition.
【Two Training Modes】
■ Practice Mode
Start with a random hand and a shuffled wall. Adapt to every draw and aim for tenpai in a realistic flow.
■ Learning Mode
Practice specific hand shapes and themes, including five-block hands, hands without a pair, multiple pairs, complex waits, and flush hands. You can also build a custom 14-tile hand and train from any position you choose.
