We will start off easy with FunkyBall. The object of this game is easy, just get your pink ball into the pink box. You move your ball left and right with the arrow keys. The key to this game is to always keep your ball under control because once it starts bouncing around all willy-nilly it is all over. On the easy level I finished up with a time of 14:54.
After you have warmed up a bit it is time to move on to The Eyeballing Game. The point of this game is to get as close to the actual geometric answer as possible. The tasks involve making a right angle, picking the center of a circle and bisecting an angle. I actually had a good time playing this game. My overall average was 7.97.
To round out the three-pack we have These Balls Are Made for Hiding. In this game you direct a laser that bounces around on hidden spheres. The point of the game is to not let any of the spheres reach the bottom of the screen, while trying to get a high score. The more spheres you hit in one shot the more points you get (click the mouse to take the shot). Every 15 shots or so the level changes and the spheres get a bit smaller and different walls are available to bounce the laser off of. This one is oddly addictive. I got to level 4 (the second red stage).
