Today's Free App of the Day is Riptide GP2
Originally $2.99

This was previously the Free App of the Day on March 23, 2014 and again on January 1, 2015. While I don't really mind repeats, this seems to be a little soon for a three-peat. !!! Anyway, it's a good-enough racing game using jet-skis. I get easily frustrated with these, but if these types of games appeal to you, I think you'll like it. Ran well on my Fire HDX.

So we have a bonus pick: ULTRAFLOW.

I recently found this for my iPad and enjoyed it so much I went to see if it was available for the Fire. And it was, yay!!! It's an arcade game. Kinda-sorta. Each level, you get an increasingly complex obstacle course of dots, bars and arrows which may or may not be moving and which sometimes have special attribues. The goal is to flick your playing piece, a small circle, through the obstacle course, bouncing off or passing through the course to the target, where it will be sucked in if it gets close enough. You have to get there within a set number of bounces. I found this quite enjoyable--I'm up to level 45 now. Some of the levels are quite challenging--it's often just the matter of a degree or so in the angle you choose to flick your playing piece.
