Geometrix Review

Geometrix is a simple collection of 3 games based on various permutations of collisions between circles, stars and squares. The three games include Chain Reaction, Star Chaser, and Orb Assault.
In Chain Reaction, the player taps on small squares to initiate a "chain reaction" which looks like a series of small bubbles. Each chain reaction garners points, Timed and free play modes are available.
In Star Chaser, squares are moved around a grid by taping the screen. The object is to collide with stars, garnering points, while avoiding red circles, which end the game. Options include Free Play, Timed mode in which a clock is continuously counts down to zero and is restored through gathering stars, and Challenge mode which challenges the user to obtain a specific amount of points. Three difficulty levels (Easy, Normal, and Hard) are available.
In Orb Assault, the square is moved along the screen by tapping at the location where you want it to go. Four color options are available at the bottom of the screen; the user chooses a color for the square, and then must collide with the corresponding circles of the same color while avoiding circles of a different color. Three difficulty levels (Easy, Normal, and Hard) are available.
Eight electronic songs options are available.
I found the games to be very challenging and not seem terribly responsive to my taps. My 4-year old got the hang of it much faster than I did (so what else is new?). The graphics are reminiscent of the 1980's Atari, but this is a solid game with enough depth to engage and maintain interest.
