The E Puzzle

These moving coin puzzles were popularised by the great English puzzler Henry Dudeney. They can be played with coins or counters and a grid or any objects that make two distinct sets.

The aim of the E puzzle is to reverse the positions of the Green and Red counters in the bold grid.

There are rules of course to make it a challenge:

*There is no passing or jumping.

*Only one piece at a time can be in the same square.

There is an A4 grid that you can print out if you like, download here.

You can use counters, coins, buttons anything you like.
