How to play
Four steps and you are mining.
Find and tap
Only tiles with nothing on top are free. Tap them and they fly to the bar at the bottom.
Make the trio
When three identical gems meet in the bar, they vanish and free up space. The bar has 7 slots: fill it and you lose.
Clear the mine
Remove every tile to win stars, coins and the mine's gem. Boards change shape and layers as you go.
Use boosters
Hint, Undo, Shuffle, Extra slot, Magnet, Hammer, Wildcard, Blast… 13 helpers for the tough levels.
More ways to play
Dynamite
Tap 3 different gems in under 3 seconds and the dynamite blows up a whole trio.
Autocomplete
From level 8, once you can no longer lose, a button appears to finish the game for you.
Time attack
Find every tile of one gem before the countdown ends. They appear in the monthly packs, the tournament, the daily challenge and the Dungeon.
Gem name on each trio
When you make a trio, the gem's name shows for a moment so you learn to recognize each stone. You can turn it off in Options.
Special tiles
12 special tiles that appear little by little as you go deeper into the mines. Each level has at most 3 different kinds, so every game feels different.
Geodes
Rock tiles hide a gem: they open when they're free
Gold core
The gem with the golden glow pays extra coins when you complete its trio
Sealed quartz
This tile is locked in crystal: the number shows how many trios you must make to free it
Key gem
Find the gem with the little key: completing its trio opens every lock
Resonant gem
When its trio is made it resonates: it opens the geodes and takes 1 off the quartz touching it
Shifting prism
It counts as any gem: tap it and it becomes the one you need most, completing your pair in the bar
Fractured crystal
Once uncovered, its number shows how many other trios you have left: complete its trio in time and you'll get a Triodyte gem
Frozen crystal
This gem is trapped in ice: only trios of the same gem melt it. The number shows how many are left
Blast geode
Uncover it and it explodes, freeing the quartz, ice and locks around it
Mineral cluster
Tapping it takes no slot: it makes its trio at once with matching gems in the bar and takes any missing ones from the board
Unstable obsidian
Once uncovered it heats up: its number shows how many trios you have left. Complete its trio in time and it bursts, freeing the tiles around it
Grand resonator
Completing its trio wakes every special tile around it: it opens geodes, cracks seals and sets off the rest
Some boosters
Hint
Shows an available trio.
Undo
Returns the last tile to the board.

Hammer
Smashes the board tile you choose, even if covered, without sending it to the bar.
Wildcard
Turns the tile you choose into the one a pair in the bar is missing, completing the trio.
