Do you have enough brain power to complete the Tower Challenge? Invented by a French mathematician in the 1800s, Tower Challenge is a puzzle consisting of six silver discs. The concept is simple. Move each disc one by one from Tower A until all discs are located on Tower C. However, you can't put a larger disc on top of a smaller disc.
You can make the puzzle as simple or as challenging as you want by playing with anywhere from four to six discs at a time. Depending on how many discs are in play, and how many moves you use to solve the puzzle, you are rated as a sharp thinker, expert or genius.
