8.9 is a superb .io game in which you must attempt to stomp other players in a platform based arena. Before you start the game, you can choose from a range of different skins and customize your character – you can also choose your username. Once you are ready, you can enter the arena and start stomping!

Use your mouse to control the movement of your character – your character will jump automatically, you must simply direct them left or right and jump from platform to platform. You must also try to collect the stars around the platforms – these will provide you with a boost and increase your characters size. Use your left click button to stomp – you can only stomp enemies that are smaller than your own character so be careful! This game has great playability and is a fun way to compete against other players worldwide so get stomping!
