Diamond Coins

Diamond Coins

Rules can get in the way of finding solutions. Demonstrate how this works with a few coins and a flat surface.

Guide lines
Ready, Steady, Go!

Arrange four coins into a diamond pattern.

You:

The challenge is to start from the diamond pattern and end up with all the coins in a straight line.

Lend me your ears

Now explain the rules.

You:

You can move one coin at a time, but every time you move it and let go of it, it has to end up touching two other coins.

Seal the Deal and Reveal

Give the person time to try out a few moves, until they acknowledge that they can’t figure it out.

You:

Ready for how to do it?

Reveal the moves in 4 steps, as seen in the photos.

You:

You don’t have to have them all touching at the same time, but when they’re touching it has to be to two other coins. There’s no rule for non-moved coins.

Some extra lines you can try

  • You created rules in your mind that I never mentioned.
  • It just takes some out of the diamond thinking.
  • Diamonds can be ‘hard’ to figure out.
Alternative ending

Try going the other way, from a straight line to a diamond pattern, using the same rules.
