Deep Trouble is a retro cave-crawler inspired by the classic Boulder Dash. Navigate treacherous underground caverns, outwit the bats lurking in the dark, and reach the exit before the clock runs out. Simple controls. Brutal caves. Zero mercy. 30 underground levels — each more devious than the last. Think you can breeze through? Good luck. Features: - Tight d-pad controls built for mobile — tap once for a single step, hold to keep moving - 10 lives stand between you and a fresh start from the top - Race against the clock — your score is all about speed - Boulders and bats have a lot to say about your performance - Stuck on a level? Long-press to skip it — but it'll be waiting for you at the end - Shake to restart (we understand) - Earn a grade from C to S when you clear all 30 levels No diamonds to collect. No power-ups. No hand-holding. Just you, a cave full of problems, and a door somewhere at the end of it. Deep Trouble. A Delulu adventure.
Gem Digger

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.

Verdict
The clearest difference is in-app purchases: Deep Trouble at none against Gem Digger's 6. Deep Trouble also leads on ads (none vs shown) and update cadence (every 9 days vs every 3 months). Gem Digger's advantage is iOS requirement (15.0 vs 18.0). On price and device support there is nothing between them.
