How to play

1. Walk into rocks to mine them.
2. Collect coins and gems.
3. Upgrade your pickaxe, boots and pickaxe size until one swing clears 81 rocks.
4. Stand next to a stall, gate, chest or ladder to use it.
5. Open the chest in the middle of each level to get the key to the gate below.

Gates, drills and the bottom of the mine

• Each gate is guarded by extra health, a pickaxe requirement or a puzzle.
• Buy drills that roam the mine by themselves, and call them down from the control center.
• Gather ten drills to chew through the shiny wall.
• At the bottom is a 200,000 HP rock, and below it a cavern where someone is waiting with a question.

Slime Miner controls

• Desktop: WASD or arrow keys to move; P for settings.
• Mobile: drag the joystick to move.

Mining and using objects need no extra button: walk into rocks, or stand next to a stall, gate, chest or ladder.

Tips from the official page

• Upgrade pickaxe size, not just power, since bigger swings clear more rocks at once.
• Head for each level’s central chest to get the gate key.
• Check the gate’s guard (extra health, pickaxe requirement or puzzle) before you commit.
• Build up to ten drills for the shiny wall.

Are there Slime Miner codes?

No. The official page lists no codes or cheats.
