Since 20 is a multiple of 4, the dreidel works exactly like a regular dreidel. 

It is reminiscent of the dice in Dungeons and Dragons. 

The dreidels come in packs of six: three are white with black lettering, three are blue with gold lettering. 

Includes a card on the package explaining how to play.
