Brainstring Advanced - Brain Teaser
Serious Item Code: 424
Brainstring is today's most fascinating 3D puzzle. Based on a uniqe concept, Brainstring calls for a new way of thinking. Combine intuition with structured thought, and experience the fun of unimaginable possbilities!
By nature, man likes to unravel knots.
Any string inside Brainstring's unique 14-sided shape can be moved without creating a knot. It sounds impossible, because itís exactly the movement of a string that creates a knot, after all. Embodied in this contradiction is the mystery and surprising aspect of Brainstring!
Building on the original Brainstring, Brainstring Advanced is enriched with coloured strings. The shape and position of the strings (who do not touch) is 100% symmetric.
So how do you play Brainstring Advanced?
Move the coloured buttons from hole-to-hole and from surface-to-surface to position:
1) Any three different colours on each surface but finish with no entangled elastic strings.
Three of the same colour on each surface but finish with no entangled elastic strings.
2) Any two of the same colour on each surface but finish with no entangled elastic strings.
3) While moving the buttons from surface-to-surface the strings get entangled creating a knot inside; to finish,
you must untangle the knot so all elastic strings go straight through the middle of Brainstring Advanced and
they do NOT touch each other.
