Looking for an extremely casual yet challenging game that you can pick up and play whenever you've got a few minutes to kill? UltraFlow 2 will fill that void nicely.
The gameplay mechanic is somewhere between shuffleboard and miniature golf, where your goal is to launch the puck to the goal with a limited number of bounces. As you advance through the game, the stages get more complex and puzzling, but there's no penalty for failure. You're free to play around and tweak your shot until you figure it out. It's a free game, with an in-app purchase to upgrade and remove ads. The ads aren't intrusive, and only pop up when you're moving onto a new section of levels. Plus, if you love UltraFlow 2, you can always double back and play the first UltraFlow which is also free.
