Bubble Burst from Z-Games has been available over at the Windows Phone Marketplace for some time now. Bubble Burst is an entertaining version of the classic bubble burst games where you try to find combinations of two or more of the same colored balls in an effort to clear the screen. The larger the groupings, the more points you earn.

Z-Games has recently released the sequel to Bubble Burst, aptly named Bubble Burst 2, that brings a few more features to the mix.

Bubble Burst 2 retains the three game modes of the original (Classic, Rush, and Marathon) as well as the weekly challenges. Bubble Burst 2 adds a multi-player mode where you can challenge players from the online leader board, friends or find an opponent at random. There's also new themes to the game that become unlocked as you earn achievements.

All in all, the new additions to the game look good and add to the appeal of a pretty decent Windows Phone game. Bubble Burst 2 is a free game which you can download here (opens Zune) at the Marketplace.
