Tri 2: Tri Again for Mac

From Day Late & Dollar Short Software:

CAUTION: You're about to enter the Three-Spin Zone.

Con-TRI-ption --the unusual tri-geared contraption-- traverses a triangular game area by feeding a single loop of chain through three large motorized gears and three small pulleys. The challenge is to master the gearing system to make the Con-TRI-ption go where you want, accumulating fuel and points while avoiding deadly tri-pedoes.

Adding to the challenge in Tri 2 are new spinners that temporarily change the positions of the color-coded gears ... and triple the value of the point targets.

Note: Until registered, the game displays scores using Trinary Numbers.
