Might be easier than it seems given that there are only '6 faces' to the object, Just rotate to the right 4 times, then check the top and bottom. Right?
Nice idea - except each of the six faces has four possible orientations (imagine a compass on each face, N, S, E or W could be pointing upwards), so it's more like 24 possibilities? Might be wrong. Either way probably much harder to keep track of mentally.
