Duper is a browser-based strategy game that merges elements of war games, resource management, and social interactions usually found in Poker, into a unique competitive experience. Players participate in five-player free-for-all matches, where the goal is to dominate territories, trade strategically, and outmaneuver opponents using clever decision-making. However, victory isn't always the ultimate goal. In Duper, the dynamic mechanics sometimes reward players for cooperating with others or even enabling another player's win—adding a new layer of depth and unpredictability to the game.
