Vili.io presents itself as a highly engaging and addictive multiplayer online IO game focused on the theme of fidget spinners. Firstly, enter a chosen nickname, select a desirable skin, and then start your spinner. Navigate across the screen to gather food items, and this will make your spinner rotate at an increasingly faster pace. For each piece of food collected, the rotation speed of your spinner will increase by 1 RPM. However, remember that every 5 seconds, the rotation speed will decrease by 0.1 RPM. So, stay active to avoid your spinner gradually coming to a halt.
