I bet you already know how to play Unblocked Bubble Shooter. This is a very, very popular game which can be played on desktop and on mobile. The aim is pretty simple: the game gives you one bubble at a time, with different colors. You need to shoot it in the middle of many other bubbles, possibly with the same color. If you are able to get 3 or more bubbles of the same color next to one another then you will pop them and they will disappear. You need to make all bubbles disappear to win the level but watch out: as you go on the game will get harder and harder.
One useful trick: take your time before shooting. Missing a shot and placing your bubble in the wrong position could give you many troubles. It’s a lot better to slow down a little bit than missing many shots.
