Is a rotated solution valid in Q-Bitz?
I don't know the game well, but looking it up it looks like there is nothing that specifically identifies an orientation for the player boards, nor is there anything on the pattern cards that show what part of the pattern is up. When playing a game like this, players are probably sitting around a table, each of them will see the pattern card from a different direction then, from their perspective a different direction on the pattern card will be &quot;up&quot;. Given these things, I would say that there is no directions in the game, that as long as the pattern card and/or players tray can be rotated to match, then the pattern does match.
Though it's not conclusive (the rules are pretty short) on the MindWare company website page for the game they show an image of a game in progress with the player boards in all different orientations, most of them roughly 90 degrees rotated from the pattern card, see here:

This suggests even more that rotation of the board does not matter.
