In de (originele en de) Nederlandse spelregels staat alleen de verticale rij genoemd. Ook de Special case staat niet vermeld. Dit is later door Plan B Games ter verduidelijking toegevoegd.
Dit is wat er nu extra bij staat:
Citaat:
Also keep in mind that in each horizontal line, no color may appear more
than once either.
Special case: In the wall-tiling phase, it may happen that you are
not able to move the rightmost tile of a certain pattern line over
to the wall because there is no valid space left for it. In this case,
you must immediately place all tiles of that pattern line in your
floor line (see Floor line).
