Tahúr: A Blackjack Adventure is a blackjack roguelike. Instead of playing against the house, the player plays twenty-one head to head against rivals, using powerups that bend the rules and permanently marked cards that change how a card counts. Each district is run by a kingpin who breaks their own table's rules once pushed to match point. The game includes a story campaign, an endless Ladder mode, a seeded Daily Deal, and online duels in which both players draft powerups of the same tier and play a shoe of randomly marked cards.
