Discard Reading Trainer​ A Tactical Study Tool for Mahjong Opponent Analysis Discard Reading Trainer is a tactical study tool for mahjong players who want to master the art of reading an opponent’s river—the sequence of discarded tiles—to infer hand shapes, waiting tiles, and danger zones. The app is a coach, not a casino. There is no chip betting, no slot machine, no real-money play, and no chance-based gameplay. Every screen is designed to sharpen observation, deduction, and defensive judgment. What You’ll Find Inside Practice Bank​ 10+ scripted opponent rivers across difficulty bands. Each scenario becomes a multiple-choice drill distinguishing dangerous tiles from safe ones, complete with detailed explanations. Danger Heatmap​ A 9-column grid mapping every numbered tile and honor to a color-coded threat band derived from your reading parameters. Pattern Atlas​ A library of common reading patterns: honitsu, tanyao, toitoi, chiitoitsu, junchan, yakuhai pair, open-hand speed, and tedashi stream. AI Commentary​ Each scenario includes a written breakdown explaining why a tile is hot or safe and which rules apply—genbutsu, suji, no-chance, or one-chance. Mistake Review​ Logs every misread move and attaches the corresponding lesson, allowing you to audit your progress over time. PDF Report Export​ Generate a printable, shareable PDF for any scenario, complete with tile grids, river diagrams, threat gauges, and commentary. Customizable Reading Depth​ Adjust reading depth, defense weight, aggression weight, suji sensitivity, honor penalty, and tedashi boost to simulate playing styles ranging from cautious tanki defense to aggressive push-hands strategies.
