Casino is a game I was introduced to as a kid, a game popular among the Jewish community. It's a great game, quick, fun, and I recently introduced it to my nephews and now they regularly wipe the floor with me when we play.
It takes a bit of explaining so here goes.
Ideally for two players only; the dealer gives two cards to the opponent face down, then two to himself face down, then two face up in the middle, and then repeat. So four each and four face up as discards.
Each turn a player must play a card, if no trick can be made you just add one to the face up discards. Tricks are made by matching or building. Each time you do this you must announce what you're doing, this will become clear later.
So; if there's a 4 on the table, and you have a 4 (suit is irrelevant) you say " four" and you take the 4 with your 4 and place them next to you as your earned cards. Next player goes, the dealer, and he can do likewise. All 13 ranks including pictures can be taken in this simple way.
Now building; if there's a 3and a 6 on the table and you have a 9 you can take all three. You place the 3 on top of the 6 or vice versa, say" nine" and take them with your 9. Now if there's a 3 and 6 and you have two 9's in your hand you can take all four but only over two turns. Turn 1, move 3 + 6 together say " nine" put one of your 9's from your hand on top , and wait your next turn.
Your next turn, take with other 9 . BUT if the opponent has a 9 too , thanks pal! he can take the 3+6+ your 9 with his 9. Tough luck. Or if you , going back to previous example, added the 3+6 and had an ace and 10 in your hand, you say "ten" and place the ace on top , ready for your next move to take them with your 10, if the other guy has a 10 too, tough luck again, he'll have them.
Double building; if there's a 2+4 on the table, and you have a 1(ace) and a 7 , you can place 2+4 together place your ace on top saying " seven", but if your opponent has 9 in his hand , and there's another 2 on the table, he can place that two on top of your 2+4+1, say" nine" and play his 9 and capture all five cards.. Very tough luck for you!
Matching ranks can be built upon, without increasing the aggregate i.e. a 3 on the table, and you have two 3's, place one on top of the the one on the table, say "three" , that's why you need to say what you're doing, you're matching 3's , not adding to make 6.
Next turn you take with your other three, as they are two of target total i.e. two threes, no building can be done adding to the total. In other words the target is " three" , there's two of them on top of each other, the other player can't add a 4 and say " seven", because 3+3+4 doesn't equal 7!. Of course if he has the other 3 then he can take them.
Picture cards obviously are not used in building, just removed in matching pairs.
After the initial hand , four goes per person, the dealer deals another four face down cards to each player , two at a time, the single game is over when all card dealt,whoever takes the last trick in the last hand, takes all the remaining discards to add to their pile.
Now the points; certain ranks , and cards have special value, so during the whole game you're trying to capture these if possible.
There are 11 points per game to play for;
Whoever has most cards 3pts
Whoever had most spades 1 pt
Each Ace is worth 1pt
2 of Spades is known as little casino and is worth 1pt
10 of diamonds is Big Casino and is worth 2pts.
So after first game the score might be 7 to 4. Usually the first to 21 win.
Money is often gambled big time. Ten pounds or dollars per point, so 7to 4 score means one player is up 30 pounds after one game. My dad and great uncle used to play this , incredibly quickly, five minutes for one game, 15 minutes to reach 21 points, one of them always stormed out of the room " hell! Just lost 100 quid stupid bloody game!"
