Tai calculator: tap in your hand, see every tai and who pays what
No checkboxes to tick. Enter the 17 tiles, how you won and who is dealer; the calculator finds every tai and works out each seat's payment, dealer and streak included. If your table plays differently, change the rule and the result follows.

How it works
A whole hand in thirty seconds
1
Tap the tilesPress Clear first. One tap per tile; for a claimed set pick 吃, 碰 or 槓 first, and one tap adds the whole set. The last tile you tap is the winning tile.2
Say how the hand wentSelf-draw or discard, seat and round wind, who is dealer and the streak, your stakes.3
Read the resultEvery tai on its own line, the total, then each seat's payment, with the dealer tai on the dealer's line only. You can paste the link straight into the group chat.Why is the dealer tai not in the total?
The dealer tai and the 連N拉N tai count only between the dealer and the player paying. When a non-dealer self-draws, only the dealer pays extra; between two non-dealers, nobody does. So the total is the hand's own tai, and each payment adds the dealer edge where it applies.
The tai differ from what my table plays
Open "Your table's rules" and set what you play: 見花見字, 字一色 at 16, 天胡 at 32, 花槓 at 1, no 河底撈魚, or 連 without 拉. The result follows, and the link remembers it.
Where do the numbers come from?
The same game engine the app uses. The defaults follow the majority of Taiwan-domestic sources, listed on the tai table.
