Orbit Slingshot: let gravity steer.

How to play Orbit Slingshot

1. Pick a mission on the map. Tier 1 has one planet, tier 2 several, and tier 3 adds orbiting moons and black holes.
2. Drag anywhere on the space map, away from where you want to fly, and let go to launch. A longer pull means more speed.
3. The dotted line shows how your flight starts. It gets shorter in higher tiers, so you have to predict more yourself.
4. Reach the swirling portal to finish. Fly through both stars on the way for three stars.
5. No mouse? Use the ▲ ▼ ＋ － buttons, or the arrow keys and Space.

Tips and strategy

• Slower probes curve more, because gravity has longer to act on them.
• Aim to pass a planet's side, not its centre: that is a gravity assist.
• The pull gets much stronger close to a planet (gravity follows an inverse-square law), so a near pass bends your path a lot.
• Moons start in the same place every launch. Time your shot to their orbit.
