The Chasm: Old Chou's Treasure Digging Game Explained | Genshin Impact
An explanation of how Old Chou's Treasure Digging Game works and a guide walkthrough of one of its rounds as an example. The rules are:
1. An empty hole means none of its neighbors are bombs.
2. A hole with vegetable(s) means exactly 1 of its neighbors is a bomb.
3. A hole with Iron Ore(s) means exactly 2 of its neighbors are bombs.
By uncovering holes to give you clues and remembering these rules, you can maximize your chances of avoiding bombs and getting closer to finding the treasure.
Winning the game 3 times will also grant you the Achievement "Ding Ding Ding, We Have a Winner! Again!".
