Cuby - level 3 discontinued now
Price: £9.50 / €10.45
This cube, designed by a Dutch man called Oskar can be defined as a maze through which a loop has been interwoven. The position of the piece trapped inside can be changed by moving it in certain unique ways. When first invented, the start point at which the piece can be removed was not fixed. However, following a suggestion by the Japanese inventor - Nob Yoshigahara, a clear start point was created by adding two eyes and a mouth.
