Over-and-Under is a moving-balls twisty puzzle. The puzzle was inspired by
Devin Montes' Chain Puzzle. However, where Devin's puzzle has only a single viaduct, Over-and-Under has two of them. The puzzle is scrambled by moving the balls and clicking the two halves between their six states. The two parts are held together with magnets: twelve 3x3-mm cylinder magnets, and two 5x8-mm. The balls are 10-mm-diameter delrin balls. The puzzle is easy to solve, just systematically sorting color by color.
