Tower of Hanoi
Can you move the coloured discs from one peg to another?
You can only move one disc at a time and you can not put a bigger disc on top of a smaller disc. If you need any help click on the hints window.
The minimum number of moves you will need to make to move all five discs from one peg to another is 31.
Make your own
You can make your own tower puzzle at home using coins. You will need five coins of different sizes. For Australian coins you need a 5¢, $2, 10¢, $1 and a 20¢. Draw three circles on a page to represent the pegs, then put the coins on one of the circles.
This puzzle is just one of the 500 puzzles in the Tenix Questacon Maths Squad — an outreach program which travels around Australia making maths fun for everyone!
