Square Up - How to Play

About Rubik's Race, from BoardGameGeek:

A real time game reminiscent of Alex Randolph's Square Off but using Rubik's cube colors as a basis. In this game players race to complete a puzzle. Each player has a 5x5 slide puzzle with one tile missing. At the beginning of each round, the "Scrambler", a device that looks like a 3x3 Boggle grid with the cover on -- but using colored cubes instead of letters -- is shaken. Players then try to make the 3x3 center of their puzzle match the Scrambler.
