Dig into a collapsing cave, grab your gem quota, and reach the exit before the clock runs out. One wrong dig and a boulder lands on your head. Gem Digger is a boulder-physics puzzle game in the classic cave-arcade tradition. The first world and unlimited Endless runs are free; three more worlds are one-time unlocks. Rocks and gems fall and roll by rules you can learn, so a cave is something you solve, not something you grind. FREE, WITH NO TIMERS • Dirt Mines: 60 handcrafted caves • Endless mode: unlimited generated caves, free forever, each one checked against a solver before it is served • No energy meters and no lives to wait out, in the free worlds and the paid ones alike MECHANICS TO MASTER • Drop a boulder on a butterfly and it bursts into the gems you need • Wall the amoeba in and it turns to gems; let it sprawl and it turns to rock • Magic walls turn falling boulders into gems, but not for long • Outsmart fireflies, and learn slime and the falling-rock rules • Chase three stars on every cave; the third one needs a clear under par THREE MORE WORLDS Crystal Caves, Magma Depths and Frozen Hollow add 45 caves each. Each is a one-time in-app purchase, or take all three at once. No subscription, no consumables, nothing expires, and a single purchase restores across your devices. Built for touch: swipe anywhere or use the on-screen pad. Landscape, and it plays offline. Gem Digger shows ads between runs. A one-time Remove Ads purchase turns them off.

Gem Digger's advantage is iOS requirement (15.0 vs 18.0). On price and device support there is nothing between them.
