A daily competition and treasure dig for National Day.

Duration: 8 days

How the board works

A pickaxe opens one cell of a 6×5 board — 30 cells in all. You may only dig next to a cell already opened, and obstacles do not conduct. One of the cells hides the stairs: find them and you drop a floor.

Treasure Hunt Carbon Pickaxe — one of these per digEarth Vein Crystal — the shop currency

Auto-dig unlocks after 10 digs. The floor cycle is 300 long, after which the layouts repeat. One event cycle runs 8 days.

Digs in total430

430 digs at roughly 11.8 per floor reach floor 37, which collects 2 of the 15 depth rewards.The first one missed sits on floor 40.

The same run banks about 8,341 crystals (Earth Vein Crystal) — against a top shop slot priced at 12,000.Currency is not what stops you, though: the shallowest locked slot asks for floor 40.

What the cells hold

A floor's layout comes from its archetype, and the 300-floor cycle deals them in a fixed order. Shares are per dig; tap a row to open the reward pool.
