Also included is a guide for helping to explain game play to new players and a prototype "Card Value System" which can be used to enhance solitaire play of the game. Inserted into the card sleeves along with the cards is a small piece of cardstock with numbers printed on them to be used with the "Card Value System". This in not way damages or effects the cards and can be easily removed (although leaving them in the sleeve will not impact normal play of the game)
