Three Brainstrings in one box! The Brainstring 3-pack consists of the games Brainstring 'R', Brainstring Advanced and Brainstring Houdini for triple brainstring-fun.
Brainstring Houdini: The greatest escape artist of all time is tied up and needs your help to break free. Harry Houdini has been known to break free from jails, handcuffs, chains, ropes, and straitjackets. But he’ll need your brain power to wiggle out of the Brainstring knot.
Brainstring Advanced: This puzzle will tie your brain in knots! Getting a solid color on each side is easy, but you'll get tangled up trying to remove the knot in the middle. Stretch your imagination to find the solution.
Brainstring 'R': 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 degree spin that will have you on the ropes. Twist, turn, stretch and slide the puzzle in all directions to unravel the knot. Once the strings are completely separated, the puzzle is solved - no strings attached.
