Copper Vein

Copper Vein is a precision blasting puzzle deep underground. Copper veins glow
inside the rock wall. Tap a drill hole, drag the charge slider to load exactly
the right amount of powder, then hit DETONATE and watch the shockwave roll
through the seam.

Too little powder and the ore stays locked in the rock. Too much and the vein
shatters to low-grade dust, or the ceiling comes down on your crew. Charged
holes caught in a blast chain-detonate, so plan the whole face and set it off
in one glorious run.

Your pay is scored on ore recovered, ore grade and cave integrity. Earn coins
and gear up in the Blast Shop: copper drill skins, stabilizer braces, a
precision dose gauge, delay detonators, reinforced casings and the ore shield
net, each one changing the blast physics for real.

Features:
- Physics-driven shockwave blasting with chain detonations
- Ore recovery, ore grade and cave integrity scoring
- Six working shop upgrades that change how every blast behaves
- Fully synthesized sound effects, from fuse sizzle to cave-in rumble
- Endless shifts with growing drill patterns and deeper veins
