About
Kuzma the mole heads down into his mine to find the rarest gems, while Karl the raven is sure that everything shiny belongs to him. Their story unfolds in short comics between floors.
AN ENDLESS MINE
Every ten floors bring a new layer of rock, from clay and sandstone to obsidian and red-hot magma. Deeper down you’ll find crates, ice, chains, boulders, darkness, portals and fire, and side tunnels branch off the floors you’ve cleared, with stone tiles to crack and gold nuggets for every stage.
PLAY AT YOUR OWN PACE
There are no timers, moves are generous, and helmets are awarded for the moves you have left. Play one floor on a break or dig all evening.
COMBOS
Four in a row make a line gem, an L or T shape makes a blast, five in a row make a color bomb. Swap two special gems together for a combo: a bomb with a line turns a whole color into lines, and two bombs clear the entire board.
FROL’S WORKSHOP
Frol the badger blacksmith upgrades your boosters: the sledgehammer hits wider, the bomb blasts harder, the lantern shines longer. A coal shaft keeps digging while you play, and floors and side tunnels bring gold nuggets.
KUZMA’S CREW
Every helmet you earn is a little mouse helper. Put the crew to work for more coal, more nuggets and faster forging. Clear a whole layer with every helmet to win a golden helmet and a foreman.
