The popular Brainstring has been turned inside out! Brainstring 'R' is just as knotty as the original, but features a movable ball with a 360° spin that will have you on the ropes. Twist, turn, stretch and slide the puzzle in all directions to unravel the tightly wound knot. Once the strings are completely separated, the puzzle is solved – no strings attached.

I enjoyed this puzzle immensely, the only issue is that you have to be careful with how many times you let someone form the knots because the strings can pop due to the tension. I don't think this is a Level 9 more like 5 but this is still fun.
Watch video review!
