Place planets, bend gravity, and guide your probe to the goal. Gravity Well is a physics puzzle game where you manipulate gravitational fields to navigate a probe through space. Place planets, black holes, pulsars, vortices, and repulsors on the field, hit launch, and let gravity do the rest. FEATURES: - 25 handcrafted levels with increasing difficulty - Full level editor — create and publish your own puzzles - Community levels — play creations from players worldwide - Daily challenge — a new puzzle every day, same for all players - 9 languages supported OBJECTS AT YOUR DISPOSAL: - Planets of varying mass pull the probe toward them - Black holes exert extreme gravitational force - Pulsars attract with rhythmic, oscillating gravity — timing matters - Vortices swirl the probe into orbit for slingshot maneuvers - Repulsors push the probe away - Asteroids block the path — navigate around them Solve puzzles with fewer objects for better scores. Compete on daily leaderboards. Share your best runs. Build levels that challenge the world. Easy to learn. Hard to master.
Kessler Sky
Manage Earth's launch pad by strategically launching satellites. Dock them to build larger structures and earn income, but avoid collisions that create debris and lead to system failure. Compete with friends and complete daily contracts to keep the sky open.
- One-thumb satellite launching
- Satellite docking for larger structures
- Debris collision system
- Daily contracts and leaderboards
- Offline play
- Optional ad rewards

You run Earth's launch pad. Hold to choose an altitude, let go to launch. Satellites that meet in the same orbit dock into bigger ones: cubesat, comsat, telescope, lab, station, ring habitat, Gateway. Every lap they fly pays you. Cross two orbits and they collide. The debris keeps orbiting and shreds whatever it meets next. When the debris wins, the sky closes. That is the Kessler syndrome. It is your fault. You will want to go again. ONE THUMB - Hold anywhere: the marker climbs the orbit shells. Let go: launch. - Release with the arrow straight for a clean circle; release off-centre for an ellipse that crosses traffic. - The path preview turns red when it will cross an occupied shell. Every crash is a choice you made. BUILD THE SKY - Same shell, same kind: they dock into the next tier. Seven tiers, from a cubesat to the Gateway. - Build a Gateway and the Moon comes online: double income for the rest of the run. - Three daily contracts give every run a purpose beyond the score. DAILY SKY - The same satellite queue for everyone, once a day. One attempt counts, practice is unlimited. - Share your sky as a spoiler-free card. Beat your friends on the leaderboard. HONEST AND LIGHT - Plays offline. Progress saves on your device. - Free. Optional ads only: watch one to send the Sweeper drone or double your coins. - No account, no login, no permissions beyond the basics. Hand-drawn pixel art, original music and sound. Built by a small studio that wanted a space game you can understand in one second and play for a month. How long can you keep the sky open?
