- 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.
