Casino is a card game played by two players. The aim of the players is to score points by taking cards. Casino is played with standard 52-card deck. The dealer deals four cards to each player and four cards faceup on the table and keeps the rest of the pack handy. Non dealer plays a card first; players then alternate until the round is over.
You can combine the card you play with cards on the table in many possible ways.
Matching: If your card matches by rank a card on the table, you can take the pair immediately. Place the two cards facedown in front of you on the table. Face cards can be taken only with other face cards and only in pairs -- if two queens are on the table and you hold another queen, you can take only one of the queens. However, if three matching face cards are on the table and you hold the fourth, you can take all four.
Combining: If your card equals the combined sum of two or more cards on the table, you can take those cards immediately.
Building: If at least one free card on the table, plus the card you play, totals the number of a card in your hand, announce this build number and pile up the build to take later. For example, if there is a 6 on the table and you have a 3 and a 9 in your hand, you could play the 3 onto the 6 and say Building 9s. On your next turn, if your opponent hasn't taken it, you can take the build with your 9.
Your opponent can change the value of a build by playing another card. In this case, opponent can play an ace on the build and say Building 10s. This tells you he or she has a 10 with which to take the build.But if your 9 build is still there and if you have two 9s in your hand, on your next turn you can put one of them on top of the build and say, Still building 9s, intending to take the build with your remaining 9. This creates a double build. Players can't change the value of a double build.
Once you have made a build, on your next turn you must take the build, add to the build, or make a new build. Leaving a build untaken runs the risk that opponent will take it, but you may leave a build behind as long as you can add cards to it or make another play. Nothing prevents you from taking opponent's build; you can do so if you have the right card. On the other hand, nothing prevents your opponent from taking your build!
Trailing: You may also play a card by trailing it -- placing it on the table without building it onto another card. You can't do this if you have made a build that's still on the table. You must trail a card if you can't do anything else on your turn. For strategic reasons, a player might want to trail a card onto the table even though it matches the rank of one already there.
After the first round of four cards, dealer deals another round of four cards each and nondealer again plays first. Continue dealing four-card rounds until the pack is depleted, with dealer announcing last on the last round. Whoever makes the last take of the last round gets any cards left on the table.
