App description: Play the first 9 levels for FREE!

"Definitely fun...Fans of Angry Birds should like this because it has a fair amount of trial and error." -Tom Cutrofello, gottasolveit.blogspot.com

Fourbar is a game that tests your mechanical intuition. It's inspired by the four-bar linkage, one of the fundamental components of mechanical design. Players use simple gestures to manipulate the geometry of the fourbar and draw shapes that are presented on the screen (represented by yellow stars).

Fourbar includes 48 levels of varying difficulty split across 3 groups. In the first group, Freestyle, no restrictions are placed on the fourbar configuration or path. In the second group, Grounded, one or both ends of the fourbar are locked in place. In the third group, Redstars, obstacles are placed in the path and must be avoided.

Best times are saved for each level.
