Twenty pieces are used in this game, with the double ace and all blanks being removed.
The game is played the same as regular poker and is governed by all of its rules except that the hands rank differently, in the following order:
One Pair - any two doubles
Flush - any five of a suit such as six-one, six-three, six-four, six-five, six-six
Three's - and any three doubles
Four Straight - a sequence of fours such as four-six, four-five, four-four, four-three
Full Hand - three doubles and two of any suit as six-six, three-three, two-two and two-four and two-one
Five Straight - a sequence of five such as three-one, three-two, three-three, three-four, three-five
Fours - any four doubles
Six Straight - a sequence or rotation of sixes
Royal - five doubles
When none of the above hands are out, the best is determined by the rank of the highest piece.
