Each player starts with one planet, and the goal is to claim all of your opponent's planets.
Planets have a visible sphere of influence once owned by a player. A planet is claimed once another planet's influence overlaps it.
A planet produces gold and science. Gold is used to build buildings on your planets, and science is used to buy research levels.
Click a planet to view its details. Click the research icon in the upper right corner to view your research levels.
Once built, shipyards will automatically build ships, and send them out to contested planets. A damaged planet's influence growth is reduced proportionally to its condition, but repairs itself over time.
The game runs in real-time, but can be paused and unpaused with the P key.
