Abyss Jack

Draw or die. The Abyss is waiting.

Abyss Jack is a Blackjack roguelite. Every card can be your last. Fight through ten floors, beat nine bosses with tricks of their own, collect relics and raise a demon that breaks the rules for you.

■ TRY IT FOR FREE
Play for free until your first demon evolution. If you like it, unlock the full version with a one-time purchase: your demon, Abyss Mode, Daily Runs, Duels and the global leaderboard. No subscription, no ads. Your progress carries over.

■ GAMEPLAY
Blackjack against bosses who do not play fair. The Countess, the Bloodhound, the Phantom, the Oracle and five more have their own powers and a second chance when they bust. Stay under 21 and read your opponent: stand too early and you lose the hand, draw too late and you lose a life. Combos and multipliers push your score sky high.

■ OVER 30 RELICS
Between fights you buy relics in four rarities from the shop. Combine them into synergies that shape your whole run. Plus the Fate Card: pick rank and suit, every copy on the table grants Mult. No two runs are alike.

■ FIVE WAYS TO PLAY
Normal run: ten floors to victory.
Abyss: five Abyss bosses with merciless rules and oaths you swear before the descent. Bigger risk, bigger reward.
Daily Run: one seed a day, the same for everyone.
Duel: send a code to your friends, everyone plays the same cards, who scores more?
Weekly Duel: a new challenge every week.

■ GLOBAL LEADERBOARD
Every submitted run is replayed on the server card by card. What you see on the leaderboard was really played that way.

■ YOUR DEMON COMPANION
Raise one of five demons from egg to legend. Feed, train and perform rituals between runs. Four evolution stages, each one unlocks a new power.

🔥 Ignaris, the Fire Demon
Survive defeats, raise your bust limit to 24, turn a bust into a 21 or earn Mult the closer you land to 21.

👁️ Voidara, the Abyss Seer
See your next card before you draw, look three cards ahead or put your last card back into the deck.

💀 Mortix, the Death Whisperer
Force the dealer to stand at 16, protect life and combo on a loss, cut three points off his hand with the Scythe. His Harvest rewards every dealer bust with rising Mult.

🐍 Serphyx, the Chaos Serpent
Split your cards, poison the dealer's card, or flip the rules: in the Chaos Field, whoever goes over 21 wins.

🩸 Sanguix, the Blood Demon
Sacrifice lives for blood marks. Raise your bust limit to 26, buy Mult with the Blood Pact or call the Blood Moon, which heals for three rounds.

■ COLLECT AND CUSTOMIZE
Card decks and table cloths in the style of your demons, unlocked through your progress. Stats for every run, a run review at the end, save your progress as a file.
