How To Play

You start with three crosses on a bit of paper.

On one cross you put a pile of different sized coins

or counters with the biggest on the bottom.

(You can use as many different coins as you like.

The puzzle is quite easy with three coins, but with

more coins it gets trickier!)

The idea is to move the whole pile from one cross to another but:

- you can only move one coin at once
- you must never put a larger coin on a smaller one.

## Here's how to start with 3 coins. |

If you've had trouble understanding how to do it,

you can see the puzzle actually being solved

in front of you on the screen below!

Choose how many coins you want to start with

(or "random" if you're feeling a bit crazy)

then click START to watch it work.

You can also choose how fast the "coins" move.

If "C" = number of coins, then moves = (2 |

PARTY TIP: if you're having a particularily dull evening, why not invite some friends round for pizza and select "8" coins and set it going on the slowest speed and all sit round and watch?
