«Quble – A Twisting, Turning, Fun Word Game!»
Quble was shipped with a timer and instructions for a variety of word games. The number shown by the consonant letters are used for scoring the words.
It can also be played like a solid color cube.
Many thanks to Hendrik Haak and André Boulouard for providing descriptions of the Quble faces and informations about the Game Book.
