The Card Pentagon

Make a rough pentagon on a large sheet of paper.

Then throw down the ten non-court cards of a suit at the places indicated in the diagram,

so that the pips on every row of three cards on the sides of the pentagon shall add up alike.

The example will be found faulty.

After you have found the rule you will be able to deal the cards into their places without any thought.

And there are very few ways of placing them.
