There are several different bubble games out there so if this is the type of game that you are looking for, rest assured that there is one that will be right for you. Most of these games are some type of match three games with bubbles where you either move them around or shoot them out of a cannon to make multiples of three. These games are a matter of skill but are great to kill a little bit of time.
Some cool bubble games are bubble shoot and bubble smile. Bubble shoot is a game skill that you can download onto your phone or play online. In bubble shoot you have two different game modes to play in where you can shoot the bubbles out of a cannon trying to match three or more bubbles of the same color. Bubble smile is very similar except instead of shooting out the bubbles you swap them with nearby bubbles. Be warned though, once you start playing they get addicting and you may be at it for hours on end.
