A challenging and beautiful puzzle devised in 1883.
Can you move the tower to one of the other 2 pegs without ever placing a larger ring over a smaller ring?
Originally called Tower of Brahma, and designed by French mathematician Édouard Lucas.
To solve through any layer requires a minimum number of moves of 2 to the N power minus 1, where N is the number of rings. Solving this 7 ring version of the Tower requires 27-1 — a minimum of 127 moves!
This is not an "all or nothing" puzzle. Whatever layer you solve though is a measure of your proficiency!
Requires focus and concentration and the ability to recognize and remember patterns.
Comes with wood box that encases all the pieces, and measures about 8.25 x 3.25 x 1.375 inches when packed away.
Difficulty: 3 out of 5.
Recommended for ages 6 and up.
