One of the most extensively played card games of relatively simple nature, Casino, or Cassino, is of Italian origin, derived from Papillion, a game that is described in a book published in 1768.
Casino is a game for two, three, or preferably four players who play partners, two against two.
A standard pack of 52 cards is used, face cards having no numerical value, aces one, and the others their pip values. Hands of four cards are dealt to each player, and four cards are placed face up on the table. Then, in turn, each player tries to take as many cards as possible by matching the cards in his hand with those on the table. A combination may be taken in when a player holds a card in his hand of the same denomination as a card on the board; for example, if there is an eight on the board and a player holds an eight in his hand, he may play it and take both cards, piling them face down in combinations involving more cards.
For instance, an eight played to the board will take all other eights and any other cards that in combination total eight, such as seven and an ace or six and a two. If a player prefers, he may build combinations instead of immediately taking in cards. That is, he may place a card from his hand on one or any number of cards on the table and announce the combination that he is building; if he says 'building sevens', for instance, he may place a seven on top of a three and four, or an ace on two threes with the hope of taking in the pile on his next turn by playing another seven from his hand.
Since the face cards have no numerical value, they cannot be built. A player takes a risk in building, because if an opponent holds a card of the same denomination as those being built, he may take in the cards himself. The original builder, or any other player, may continue the build or change it by adding other cards instead of taking the pile. When a player can neither build nor take in any cards, he must discard from his hands by playing one card face up on the table.
Following disposal of the first deal of four cards apiece, the dealer deals four more cards to each player but none to the table, and play resumes as before. Upon making the deal of the last remaining cards the dealer must announce that it is the final deal; on the last deal, the player who takes the last trick takes in all cards remaining on the table. When the last trick has been taken in, the cards are counted and scored according to the following point schedule: Greatest number of cards--- 3; greatest number of spades--- 1; each ace--- 1; Big Casino, the ten of diamonds--- 2; Little Casino, the two of spades--- 1.
Normally, 11 points may be scored during each run through the pack, but if 'sweeps' are counted, the scoring is higher. A sweep, for which one additional point is given, occurs when a player takes in all the remaining cards and leaves the boards clean. If there is a tie for greatest number of cards no points are awarded in this category. Game consists of 21 points, a score that usually is not reached in fewer than three or four runs through the deck.
