Bubbles is the Palm Pre version of the popular and addictive bubble bursting game. This version is quite beautifully done and offers a relatively complete version of the game, with four different varieties for you to try your hand at. Bubbles is a product of the same developers as Spades for the Palm Pre, but this is a more polished and cleaner app. The bubbles icons are satisfyingly beautiful. Like Spades, it has a finger-width area at the bottom of the screen dedicated to advertisement. You can chose between smaller and larger bubbles. The game comes in four variants: Normal, Continues, Super, and Super-Shifter. All of them are pretty enjoyable and can keep you coming back to beat your own high scores which are tracked for each variant. 

There are no controls or major interface elements near the bottom so tapping an ad by accident is nearly impossible. Tapping the ad will launch the browser in a separate card and keep your game uninterrupted. The ad changes every time you tap a bubble, which can be a little distracting. You can turn off sounds for the game in case you’re playing in a library or other place with a need for silence. Unfortunately you can’t save the state of a game, you’ll just have to keep a card running if you are interrupted mid-game and need to come back to it at a later time. Overall, Bubbles is clean, simple, and relatively well-implemented. A worthwhile download that compares well with other implementations of the game on other smartphones.
