About This Game

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

• 31 exploration missions — Travel from Earth and the Moon to the inner planets, outer planets, and beyond.

• Gravity-driven navigation — Perform gravity assists, enter orbit, circle celestial bodies, and return to Earth.

• Pause-and-plan maneuvers — Preview your trajectory as you adjust thrust direction and strength.

• Rewind with a cost — Spend action points to revisit recent maneuver points and try another approach.

• Flight records and replays — Review your route and learn from each attempt.

• 63 unlockable space exploration records — Discover real missions through stories, images, and reference material.

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.

Connect Your Journey to the History of Exploration

Review your flights through replays and trace the maneuvers that shaped your route. Meet exploration conditions to unlock records of humanity’s journeys into space. Discover mission stories, photographs, and explanatory material, with reconstructed flight paths available for selected records.
