If you're looking for a different type of balloon busting game, iSplume might just be the game to try out next. Originally offered for sale, the game is now available as a free download on the Mac App Store. This cool puzzle game from Flash Bang Studios has gained quite a lot of fans since its release. Unlike regular puzzle bobble types, this one makes use of quirky little creatures called splumes. The objective is a bit similar to the original though. You have to position at least three similar colored splumes in order for them to pop. Of course, there are additional sets of rules that help make this one a little bit more interesting than its counterparts.
