* Flip Side *

* Designed by Ferdinand Lammertink, copyright ThinkFun 2005. *

(plastic, 3 inches by 6.25 inches with 1.5 inch diameter wheels)

Two tracks, each with five squares, can slide horizontally to three positions
(*left*, *center*, and *right*).
Each square has the same number on both sides, A pair of wheels on either side of the central 2 by 3 array of numbers can be used to flip them.
The basic goal is to make the pattern 0 to 9 (i.e., 0 to 4 on the top row and 5 to nine on the bottom row).
The directions also challenge you to make other patterns.
