This simulation centers around a special deck of cards: in addition to the standard deck of fifty-two cards there are four one (these differ from aces) of each suit and four jokers.
The deck is shuffled every time a team begins its turn at bat. Each card flipped represents a pitch and results of a pitch depend on what card is revealed.
An intermediate level game adds play options such as the bunt sacrifice and the squeeze play. The advanced level of the game uses statistics of real players. For the pitchers the players will need the ERA, the pitching arm and the strike outs per inning ratio. A batter's batting average, slugging percentage and speed rating for base running in needed to play. A device called the Raymond Dial helps the players figure out what each card flip means.
The game has rules in French and English.
