Games Like S.O.I.: Sphere of Influence

One burn can change your entire journey.

S.O.I. is a 2D orbital puzzle game where you plan your route using gravity and the motion of planets. Pause time, study your predicted trajectory, and choose the direction and strength of your next burn. A small adjustment now can change where you arrive much later.

Key Features

Pause. Predict. Ignite.

Time stops while you prepare a maneuver. Study the moving planets and your spacecraft’s predicted path to plan your next encounter. When you are ready, ignite the engine and watch your chosen course unfold.

Limited Maneuvers. Many Possible Routes.

Accelerate now, or save a burn to slow down near your destination? Every maneuver costs an action point. Use planetary gravity to change your direction and speed, and decide where each remaining opportunity matters most. Reaching your target is only part of the challenge—your arrival speed and direction can matter, too.
