Another counter sorting puzzle for iPad, Android and IWB along the lines of the Two At a Time puzzle. This is very similar as you must arrange the pattern of shapes so that there are 4 octagons followed by 4 stars with the 2 blanks on the far right. The twist with this puzzle is that every time you move the two shapes they flip relative positions. This makes it a bit harder to visualise your strategy and offers a simple to understand, but challenging to solve, puzzle.
The top blue bar lets you select which two shapes to move the lower blue bar will move the selected two shapes. You must always move two shapes.
