SIX WORLDS

Every five rooms, a new world

New enemies, new music, new dangers. And just when you think you've seen them all, it starts again. Harder.

01
Boss · room 5

Dungeon

Damp stone, guttering torches and treasure chests that bite if you get too close.

Who lives here

Warden of the Dungeon

Demon Lord

02
Boss · room 10

Forest

Roots older than the world, spores that glow in the dark and the feeling that something is watching.

Who lives here

Heart of the Forest

Ancient Treant

03
Boss · room 15

Ice Caves

Crystals that breathe, a cold that bites to the bone and, under the snow, something huge asleep.

Who lives here

Lord of the Caves

Frost Giant

04
Boss · room 20

Lava Depths

Chain bridges swaying over rivers of magma. Somewhere below, the Colossus opened its eyes.

Who lives here

Hound of the Colossus

Hellhound

05
Boss · room 25

Crypt

Open graves, candles burning violet and a king who won't stay dead.

Who lives here

Sovereign of the Crypt

Lich King

06
Boss · room 30

Desert

Dunes that never sit still, half-buried temples and a rumble underfoot that means nothing good.

Who lives here

Hunger of the Dunes

Sand Wyrm

MODES

One hero, six adventures

What you win in one comes with you into all of them. Tap a portal.

BOSSES

Every world has its master

Demon Lord

Black armor, ribs of molten lava, horns on fire. Your first real test, and it doesn't go easy.

Dungeon · room 5

THE ISLAND

The heart of the world, floating in the sky

Meet other heroes, forge, trade and pick your next portal. Tap the lights to explore.
