About This Game

Pause, take your time, and explore the Solar System.

S.O.I. is a 2D orbital puzzle game about planning routes through gravity and the motion of planets. Pause time, study your predicted trajectory, then choose the direction and strength of your burn. One small maneuver can change where you end up far into the future.

With an emphasis on thoughtful observation and planning, S.O.I. offers a quiet journey through space. Drift past planets, trace long arcs around the Sun, and make your way toward distant destinations. For anyone who loves space—or simply wants a peaceful moment watching it unfold.

Key Features

• 31 exploration missions — Travel from the Moon to the inner planets, outer planets, and the far reaches of the Solar System.

• Plan your route with gravity — Use gravity assists, enter orbit, and find your way back to Earth.

• Plan maneuvers while paused — Preview your trajectory as you adjust the direction and strength of each burn.

• Rewind using action points — Return to a recent maneuver and try a different approach.

• Flight logs and replays — Revisit your routes and watch the moments that shaped your journey.

• 63 space exploration records — Unlock stories and reference materials from real missions as you play.

• Watch historical mission trajectories — Follow reconstructed flight paths from selected real-world missions.

Pause, Predict, and Ignite

Time stands still while you prepare a maneuver. Study the predicted paths of your spacecraft and the moving planets to plan your next encounter. Adjust your burn direction and strength, then ignite the engine when you are ready.

There is no need to rush. Compare the changing trajectories, make small adjustments, and discover your own route to your destination.

Borrow a Planet’s Gravity. Travel Farther.

Accelerate now, or slow down as you approach your target? Every maneuver costs action points. Decide where to spend your remaining opportunities, and use planetary gravity to reshape your direction and speed. Reaching your destination matters—but so do your speed and direction when you arrive.

A journey that begins with a small burn can lead through planetary encounters and onward to the far side of the Solar System. Set your course, then watch your spacecraft follow the path you designed.

A Quiet Moment to Watch Space Go By

Once your burn is complete, take your hands off the controls for a while. Watch the planets move through their orbits and your spacecraft trace a long arc through space.

Planning your next maneuver and watching the journey unfold are both part of the experience. Spend some time solving a puzzle, or simply let your mind wander among the planets. Explore at your own pace.

From Your Flight Path to the History of Space Exploration

After a flight, use the replay to revisit your full route and its decisive maneuvers. Meet conditions during your explorations to gradually unlock 63 space exploration records.

Discover the stories, photographs, and reference materials behind real missions. Selected records also let you watch reconstructed trajectories of routes flown by historical spacecraft. Follow the journeys that used planetary gravity to reach distant worlds, and connect your own explorations with the history of humanity’s travels through space.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Generative AI tools were used during development to assist with portions of the game’s code, text and localization, and to create pre-generated visual assets, including conceptual illustrations for the in-game space history archive and a stylized regolith texture. All AI-assisted content was generated before release and reviewed, edited, and curated by the developer. The game does not generate AI content during gameplay.
