麻雀点数計算・符計算クイズアプリ

Entering tiles will display the score, the winning tile (and the score for winning with that tile). Selecting and arranging tiles from the tile palette on the screen will calculate and display the completed hand, the breakdown of points, the number of han, and who pays how many points.

Use this to check scores or the winning tile when you're unsure of them at the table.

It also includes quizzes for beginners and intermediate players to help them learn common pitfalls, such as calculating points from winning hands and identifying the winning tile in a closed hand (menzen chinitsu).

■ How to Use (Hands & Points)
1. Tap the tiles on the tile palette to arrange your 14 tiles. Pon, Chi, and Kan are entered via "Add Call".
2. From the arranged tiles, tap to select the winning tile (drawn tile or ron tile). The selected tile will be highlighted in yellow. 3. Set the conditions for Tsumo or Ron, Riichi, Your Wind/Pressing Wind, Dora, Honba, and Situational Yaku (e.g., Ippatsu, Haitei Raoyue).
4. Press "Calculate" to display the Yaku, Han, Fu, and Points.

■ Main Functions

・Point Calculation
Displays the Yaku, Han, Fu, Points (including classifications like Mangan/Haneman), and a breakdown of payments. For Ron, it shows how many points the discarder pays; for Tsumo, it shows how many points the dealer and other players each pay. For hands that can be read in several ways, it selects the reading that yields the highest score.

・Fu Breakdown
In addition to the result "30 Fu," you can check where and how many Fu were added, such as 20 Fu at the base, 10 Fu for a closed hand, 2 Fu for a middle wait, etc.

・Winning Tile Checker
Enter the 13 tiles you have in tenpai, and it will list all the tiles that can win, displaying the points for each tile. This can be used to check if you've overlooked any waiting tiles in multi-way waits, and to confirm which tiles are high-value.
