We couldn't put this down at toy fair!
Just as knotty as the original, Brainstring ‘R’ features an internal sphere with 360-degree spin. Twist, turn, stretch and slide the colored buttons in every direction to unravel the twist of strings in the centre. Congratulations, you’ve solved the puzzle — but now can you re-tie the ‘knot’? This one will have you on the ropes!
