Card Brawl: Dungeon Slayer is a turn-based card battle game with roguelike elements. The objective is to beat your opponents in a one-on-one fight. Each round is divided into several phases. During each phase, you can play a card from your hand. You can also move around the battlefield and use the various abilities and powers available to you. After each round, the phase is reset and the players are given a new hand and new cards to play. This process is repeated until you have won all the matches in the tournament.

You can choose to play with one or two players. You can also play with bots. The game supports multiplayer and is designed to be able to accommodate up to four players.
