Atlas of Doors

Every door shows you what waits behind it and what it pays out, so every choice is a real one. Pick a deck, descend eight floors of doors, fight what you find, and take the card, charm or heal the door promised. Beat the boss at the bottom and the Atlas opens deeper.

Five elemental decks are open from the first run: Blood spends your own health to hit harder, Flame stacks burning hits, Frost blocks and chills, Storm chains cheap cards into long turns, Cairn stacks defence and throws it back. More decks unseal as you play. 82 cards, 23 charms, 60 foes and 11 bosses, with new seasons adding more.

Win and you climb the Descent, a ladder of eleven rungs where each rung changes the rules against you. Fall and you keep your Keys, open the next door, and go again a little smarter. One Daily door a day puts your run on the board against every other player.

A run takes ten to fifteen minutes. No download, no account, no waiting. Made for portrait on your phone and plays just as well with a mouse.
