Bontãgo is a single or multi-player 3D real-time strategy game. Players begin with flags (one color for each player) spaced evenly around the edge of a large disk, called the field, balanced on a fulcrum in the center. Around each flag is a circle representing that player's controlled area. Every few seconds a block appears on each player's cursor. The players must place the blocks somewhere in their controlled areas. Players can place the block at any moment in the allotted time, or can hold it until time is up and the block will fall on its own and be replaced by the next block.

Note: DirectX 9.0b is required to play this game.
