Burrow Balls

Aim the drill cannon and let glass marbles rain into the earth. They bounce, chip and smash through the rock, and every piece you break pays gems. Shiny gem veins pay seven times more, and glowing relics hide collectible stickers.

Spend your gems in the Workshop on faster fire, heavier marbles, blast and acid marbles, twin shots and more. New upgrades open as you dig deeper, world by world. When the rock gets too tough, Rebirth: start over with fossils that make every marble hit harder for good.

- 30 hand-painted biomes in 6 worlds, from the Garden to the Heart of the World, 2.4 km down
- A Workshop upgrade tree that opens up the deeper you dig
- 90 stickers to collect in the album
- Missions, achievements and a Daily Dig with a streak chest
- Your progress is saved

Drag left and right (or move the mouse) to aim the drill cannon. Marbles fire on their own while the fuel lasts.

Break rock for gems, aim at gem veins for big payouts and crack the glowing relics for stickers. Between dives, buy upgrades in the Workshop, then dive again. Each new biome you reach becomes your new starting point. When the rock gets too tough, Rebirth for fossils that make you stronger for good. The goal: reach the Heart of the World, 2.4 km down.

Controls: mouse or touch to aim. Esc or P to pause.
