Use the right trigger button or left mouse button to grab using your moon. Grab an opponent to start depleting their health and increasing your own.
Use momentum to throw your opponent out of the ring.
You can grab your opponents moon, though if the grab portion isn’t high it won’t last long.
Health drain is reduced while swinging opponents compared to holding them still.


After being thrown you experience stun represented by a static portion of your planet. You have limited movement and cannot grab in this state.
Stun time builds up from being swung around while grabbed.


Grab the fabric of space to improve your movement options and speed.

Defence / Survival

You can buffer a grab out of stun by holding the grab button.
Grab space to protect yourself from huge bounce knockback.
Grab space to anchor yourself before your opponent grabs you.


You can hold a grab for the time represented by the bright pie portion of your moon.
Make sure to have your whole moon inside what you are grabbing to increase grab time.
Grabs last longer with less force on the moon.


Grab a star to gain some extra health. You can't grab it for very long due to its high temperature.
Draining health from a star reduces the size of the ring quickly.
Throw a star to move the ring. Stars are heavy but continue to move once they get going.


Use the left trigger button or space key to bounce your planet off of other objects. Bounce into opponents to send them flying.
The speed of your planet and overlap with your opponent increases the force and damage of the bounce.


You can bounce off of the ring to stay alive.
Bouncing the ring while grabbed reduces the grabber's maximum grab time by half.
Once a star burns out and the ring gets too small you can no longer bounce off of it.


Bounce while an opponent's moon is inside your planet to stun them and parry potential grabs.
Bouncing off an object reduces stun quickly.
Being bounced on your planet reduces stun from bouncing your moon.
Your bounce will deal half as much damage while grabbed.


The time spent bouncing is represented mantle piece of your planet.
The time is increased the more health you have making it easier to bounce.
Start a bounce while touching an object for extra core bounce force.


Spin the left stick to spin your planet in the desired direction, or use the left shoulder button / Q key for counterclockwise and the right shoulder button / E key for clockwise spinning.
Your planet will experience extra movement force sideways to your movement direction that increases with spin speed.
The spin indicator will glow white when you're spinning the left stick fast enough for maximum spin speed.


You don't have much influence over your movement while in throw stun.
Use spinning as a form of directional influence to avoid going outside of the ring.
Spin using the left stick to keep your left index finger free to bounce.


Spin while grabbing an opponent to spin your moon (and their planet) instead of your planet.
Spin while being grabbed to break out faster.
Spin in the opposite direction to the opponent you are grabbing to prevent grab breaks.
Spin in the same direction as the opponent that's grabbing you to break out twice as fast.
The spin indicator will lengthen when your spin direction is effective and shorten when ineffective.


Objects that touch the center of a wormhole will be teleported to the other hole of the same color with continued momentum.
The exit portal has a timeout that prevents objects from re-entering it. The timer pauses while objects are touching it.
If you grab an object and send it through a wormhole you'll be teleported along with it.
If you grab an object and move your planet through a wormhole you will teleport the object with you.
You can chain planets and objects together to teleport the whole chain.
If you're grabbing space and enter a wormhole your grab will be released.
You can grab a wormhole to move it.
You won't be teleported while grabbing a wormhole and entering it, until your grab releases.
You can teleport wormholes through wormholes of different colors. The faster moving hole will be the one that is teleported.

Black Holes

The orange accretion disc has a strong gravity effect. Objects that touch the black singularity will instantly die.
If your moon touches the singularity, it will be taken from your planet.
If a star inters a black hole, its heliosphere ring will be deleted, and the black hole will grow.


You can throw a bomb to put it in an armed state where it will explode on contact with planets or other objects.
You can bounce bombs to explode them for speed.
Bomb explosions cause damage, stun and knockback. Damage and stun will be reduced if you're bouncing when an explosion starts.
Armed bombs can be grabbed again to temporarily disarm them.


Use the left stick or WASD keys to move your planet.
Use the right stick or mouse movement to control your moon's orbit around your planet.


The objective is to deplete your opponent's health.
Health is represented by the bright pie portion of your planet. The black portion shows health lost and white portion shows health gained.


A round finishes when all opponents have health depleted but one. A score satellite will be filled white for the player.
A game finishes when all score satellites are filled for the winning player.


The most efficient way to deplete health is to force your opponents out of the heliosphere (ring).
The rate of health depletion depends on the portion of your planet inside the ring.
The ring reduces in size as the game progresses and the star loses power.
The ring shrinks faster if opponents are further away from each other.
