Cross Decision

This is a tool designed specifically for mahjong players to record their decisions regarding riichi (ready to declare riichi). When your opponent declares riichi, should you follow suit, discard, or defend your hand? Every choice affects the outcome and points. This app allows you to quickly record key information during breaks in the game, such as decision type, opponent's position, hand shape, waiting tile shape, turn count, and dora (treasure tile), and to record the results and point changes after the game. Through visual statistics, you can clearly see the win rate of following riichi, the efficiency of discarding, and the net points gained or lost, identifying blind spots in your decisions. The built-in strategy guide covers the timing of following riichi, discard judgment, tile reading techniques, and point efficiency analysis.
