You may play a card in your hand by discarding it in the [Play Pile] if the card is 1 number/value higher or lower. (e.g. 5 can be played on a 6 or 4, a Queen can be played on a King or Jack)
A 2 may be played on an Ace and a Ace may be played on a 2.
You may have up to 5 cards in your hand at a single time. When you have less than 5 cards in your hand you may draw from your [Draw Pile]
First player to play all of his/her cards wins!
