S.O.I.: Sphere of Influence

Orbital puzzle on PC

S.O.I.: Sphere of Influence is a 2D orbital puzzle game about plotting spacecraft routes through the solar system. You travel from Earth and the Moon to the inner and outer planets, using engine burns and planetary gravity to reach targets. The route you choose can matter long after a maneuver: a small change in thrust can alter where your spacecraft arrives later.

Plan each burn

Time pauses while you set up a maneuver. You can study the moving planets and preview your spacecraft’s predicted trajectory, then choose the direction and strength of a burn. Once you ignite the engine, the spacecraft follows the course you planned.
