convert the suit into a number

When you look at a pack of cards, you need to convert each suit to a number. If you count the points on each suit (mostly at the top) then this becomes easier.

SPADES

SPADES equals ONE because there is only one point at the top. A digging spade hits the ground at one point.

HEARTS

HEARTS equals TWO because there are two points at the top. There are usually two hearts involved in love.

CLUBS

CLUBS equals THREE because there are three points at the top. They look like a three-leaf clover.

DIAMONDS

DIAMONDS equals FOUR because there are four points around a diamond.

SUMMARY

SPADES = ONE

HEARTS = TWO

CLUBS = THREE

DIAMONDS = FOUR
