Tunnel

Step 1 of 3

Tap DIG

▼

Start a run with one tap. Your bet goes into the tunnel.

DIG puts your virtual coin bet into the run and attempts the next level.
Every safe level raises the multiplier and the potential payout. Compact HUD multipliers are rounded and marked ≈.
BANK adds bet × the exact multiplier to your balance. The game rounds the visible coin total to two decimals; the math table provides four-decimal reference values while payouts use the unrounded internal multiplier. DIG DEEPER risks the entire unbanked payout.

The red cave-in chance rises every level. Cracks, dust and rumble warn you as the tunnel gets unstable. Level 8+ switches into deep-run slow motion.

Coins are virtual only and have no cash value. If you run out, use the free refill to keep playing.
