The next Gubble game, Gubble Vacation Rush, is coming for mobile platforms in the spring of 2014. Check out the blog for more details.
Gubble for iPhone and Gubble HD are available at the Apple Appstore! You can go to the order page for a free demo or the full version of Gubble HD here . The Gubble sequel is happening. It will take some time to finish. We are porting some of the old Gubble code to Unity, and making all new graphics using Blender. Thanks to all the fans out there for your patience. We'll announce a release date when we're a bit farther along.
