Inside the Cave Digger Cabinet
TL;DR: Dig through dirt to collect gems and reach the exit before boulders find you. Expect physics puzzles at pickaxe speed at a pace that's deliberate - until gravity isn't.
Cave Digger hands you a cave full of dirt, a pocketful of ambition, and physics that do not care about either. Dig tunnels to reach the gems, but remember: every boulder in this cave is held up by something, and that something is often the dirt you just removed. Boulders fall the instant they lose support, roll off rounded edges, and flatten careless miners.
Each level sets a gem quota - Hit it and the exit opens - And a timer that turns tidy plans into scrambles. The tension is glorious: dig slow and the clock eats you, dig fast and the ceiling does.
Our version keeps the classic tile-by-tile physics crisp on keyboard or swipe, chains levels with rising quotas, and offers a daily seeded cave where every player mines the identical layout. Same boulders, same gems, same countdown - See who walks out richest on the leaderboard.

Learn Cave Digger in Five Moves
Dig through the dirt
Move into a dirt tile to carve it away and pass through. Dirt is also the cave's scaffolding - It is often the only thing holding a boulder over your head.
Mind what is above you
The moment a boulder loses its support, it falls. A falling boulder is lethal; a resting one is just a wall - So always check the ceiling before you dig the floor.
Watch boulders roll
Boulders do not just drop - They roll off the rounded tops of other boulders and gems when there is space beside them. One dig can start a slide three tiles away.
Fill the gem quota
Each level shows how many gems you need. Collect that many and the exit opens - Everything past the quota is profit, if you live to spend it.
Beat the clock to the exit
Every cave is timed. When the quota is met, weigh each extra gem against the ticking seconds, and reach the exit before zero or the run ends where you stand.
Score Higher at Cave Digger
Read the whole cave before your first dig. Tunnels are permanent - You cannot put dirt back - So one greedy early dig can drop a boulder that seals off a gem forever.
- Approach gems from the side. Grabbing a gem from directly underneath a boulder stack is the genre's oldest funeral, because the gem may be the only thing holding the pile up.
- Trigger falls on purpose from safe ground. A hair-trigger stack never gets safer - Poke it loose from a protected angle now, rather than tiptoe past it while the timer screams later.
- Never pause under a hanging boulder. You can dash beneath one that has not started falling, but a moment's hesitation in its shadow is the difference between mining and archaeology.
- Leave pillars of dirt as brakes. Strip-mining a whole chamber feels efficient until every boulder in it moves at once - Untouched columns keep the ceiling honest while you work.
- Scout the expensive pockets early. Check the guarded gem clusters while the timer is fat, so your late-level route is a plan instead of a gamble.
- Leave when the quota says leave. The timer ends more runs than the boulders do, so once the exit opens, only detour for gems that sit on the way out.
