9.1 is an online physics .io game where you compete with up to eight players. The goal is to defeat your opponents by pushing them into deadly objects (or off the map). Alternatively, you can watch players do this to themselves. Last person standing wins.

How to Play


The quick play options let you play straight away. Use the arrow keys to move and the X ket to make your circler harder to push. The main aim is to push your opponents off of the map or cause them enough destruction to make them explode.

Bash enemies using your jumps, and move and hold the X key to gain weight and move platforms of objects. As you play, you will get used to the game mechanics. Each level has a different challenge - you must be alert and assess the situation quickly.


Customize your character (circle) any way you want and fight up to three other people in one of the hundreds of different, player customized maps. You can make your own maps using the level editor.
