Closed only
Difficulty: ★★★★★
Requirement:
- Non-dealer wins by self-draw on their first draw
Origin & Trivia:
If Tenhou is Heaven’s blessing, Chihou is Earth’s. The term mirrors ancient Chinese “three powers”
theory (Heaven–Earth–Human), where the Earth supports but does not command. The player receives
a natural win the moment they interact with the wall for the first time — a rare alignment of luck and timing.
