Oktagon is two separate puzzles. In one, from our shareware game "Uncle Julius and the Anywhere Machine", you must rearrange a set of irregular shapes to form an octagon. In the other, you must correctly orient six linked, nested octagonal rings. Oktagon comprises two separate octagonal puzzles. In the first, you must rearrange a set of four to eight irregular shapes to form an octagon. This is based on a puzzle in our shareware game Uncle Julius and the Anywhere Machine. In the second puzzle, you must rotate six concentric octagonal rings until all have the same orientation. The catch is that the rings are linked, so that rotating one also rotates one or two others.
