麻雀: 牌効率トレーニング「牌トレ！」

■ What is "Hai-Tore!"?
"Hai-Tore!" is a training app that hones your mahjong tile efficiency and playing style through "Which tile to discard?" (deciding which tile to discard) and "One-Game Play" (consecutive discards).

Based on multi-turn foresight considering the remaining tiles, dora, and prevailing wind, it determines the best move using indicators such as expected value, winning probability, and tenpai probability. It helps you develop the ability to discard tiles based on reason, not just intuition.

■ Three Practice Modes
【Normal Mode】
General "Which tile to discard?" problems. Solidifies the basics of tile efficiency in various situations.

【Pure One Suit Mode】
A "Which tile to discard?" mode specifically for pure one suits. Trains your judgment skills in complex situations.

【One-Game Play Mode】
Simulates 17 consecutive discards. Choose the best move each turn, training your tile efficiency in a flow close to actual play.

■ Extensive Problem Bank
- Discard Problems: Over 5,000 questions (Total for Normal and Pure Straight modes)
- Single Game Plays: Over 1,000 games

■ Instant Results Review
After each question, feedback is displayed, including a comparison of correct/incorrect answers and the number of tiles that can be accepted.
Even subtle decisions (close calls) are visualized, making it easier to understand "why that discard was made."
