You are in the world of Dotz.io in order to play and win. In the game, you control the ball, which absorbs a lot of multicolored points. They add weight and size, which makes your character stronger.
The whole game is built on levels. In order to move to a new level, you need to sit down a certain number of balls that are scattered on the playing field. The sphere you are controlling begins to grow to the marks indicated by the dot-dash. After the entire area is filled with color, you go to the higher level.
Beware of balls that are bigger than you and stronger. In Dotz.io, players from all over the world control similar spheres. You need to absorb them as well, but you need to look at their size. If they are bigger, then go away, otherwise they will eat you up. But if a player of a smaller size, you can safely attack him. Manage your ball using the mouse. Left button you can speed up your character.
