About This Game

Every card is a spell, and a passage

Flip any card over and you'll find a corridor, a crossroads, a lair or a chest. In Sigildeep you build each dungeon one card at a time, laying passages in front of you as you walk. But every card you lay is a spell you can no longer cast. Spend too freely and you'll reach the keeper with nothing left in your hand.

Fight with what's left

When something crawls out of the dark, the cards you kept become your deck. Play them for damage, block, poison, summons and stranger things. Every card carries a glyph, and the last five you play form a string: three alike make a triad, five make a fivefold, and the right sequence of three casts a hidden glyph spell.

Thirty dungeons, thirty keepers

Each dungeon ends at a keeper's door: dragons, giants, a djinn, a hydra, a warlord. Keepers fight with decks of real cards, and when one falls, its deck is yours.

Open packs, build your binder

Packs come from monsters, chests and keepers. Tear them open and turn each card over: common, rare, epic, legendary, and every so often a holographic one. Your binder tracks all 300 kinds of card across ten elements. Lock away your favorites, evolve your copies, and build the right deck for the dungeon ahead.

Painted in letters

Every monster, card and creature in Sigildeep is drawn in layered ASCII glyphs, from 74 monsters down to the smallest spark. The game runs at a crisp 1280x720 with an optional CRT screen.
