What is All simples (タンヤオ)?
A hand with no terminals and no honours — the easiest yaku to build, open or closed.
Han and calls
1 han（Open is fine）
How it is formed
- Every one of the 14 tiles must be a 2 through 8 in a number suit.
- No terminals and no honour tiles anywhere in the hand.
- By default on this site it counts even when you have called tiles.
Example hand
Winning with this shape gives the following.
- Yaku scored：Pinfu・All simples・Menzen tsumo
- Fu：20 fu／3 han
- Points for this example：3,900 points（Tsumo）
This opens the practice board with the hand already set up; press Tsumo to win with it.
Yaku it combines with
Watch out
Whether open tanyao counts varies by house rule; here it counts by default, and the party settings can turn it off.
Questions
How many han is All simples?
1 han, whether the hand is closed or open.
