Dominó Dungeon is a fast-paced, fun, and competitive game where each player controls an Adventurer who faces the dangers of Dungeons to earn money and double-cross the other members of their party. Players use domino-style tiles to navigate grid-based dungeon maps, rolling dice to resolve encounters and managing their hand of cards. Each adventurer has unique abilities, and the game features scenario-based missions that keep the action fresh. With action points to spend each turn, players must decide when to explore, when to fight, and when to betray their companions. The player who earns the most gold wins.
