Duper is a 5-player free-for-all game where strategy meets social trickery.

In an average 20-minute match, 5 players compete in real time to build power, make deals, and come out ahead. Each match is a contest of economics, diplomacy, and betrayal: gather resources, expand your position, negotiate trades, and decide when to cooperate and when to strike. Players compete for precious Duper Gold (🧈), the sole hard currency in the Duper ecosystem, by outsmarting each other in games.

Game Elements and Key Features

On a dying red star, every evolution begins with a surrender. And so, the story begins.

Session starts after you match with 4 other players. In ranked mode, you can bid to compete for player colors with earlier turn order, such as Red.

Build soldiers, tanks, planes, and forts to grow and defend your territory. Build research centers to boost your economy, unlock global trade, and acquire special unit types.

Control territory on a shared map by expanding, capturing tiles, and pressuring your opponents.

Press your advantage by using emblem cards and raising any time. Higher risk, higher reward. Not recommended for the lighthearted.

Trade cards, blueprints, and keys every round, not just to get ahead on resource management, but also to develop important alliances.

Transform your base to a superunit for unrivaled combat power, by sacrificing all your future coin yield. Only for a true gambler.

Engage in free-form diplomacy with chat, quick messages, and emojis. Whether it's genuine or just to make your next backstab more seamless, no one will ask.

Only 1 player ends each game. However, everyone who holds his keys gets a share of the prize pool. Win-win situation is entirely possible—as long as someone loses big.

Outside the core game, acquire emblem cards, rare cosmetics, gold vouchers, and more in lootbox via Duper Gold, the sole hard currency in Duper.

Every game revolves around reading other players and adapting on the fly. Alliances can help you survive, but they are never permanent. A smart deal, a timely betrayal, or a well-planned attack can completely change the outcome of a match.
