The key to the game is picking your hand and remembering what you threw away. Shuffle the deck, place upsidedown on the table. Each player takes turn, two cards at a time until you go through the whole deck. Then the bidding is the same as Spades where a 1 bid means you will take 1 trick. The scoring is 10 point per trick bid and 1 point for every overtrick.
Some people play sandbags.
If so, everytime you get 10 sandbags, you go back 100 points. 500 points is game. Sandbags are where you make more tricks than you said you would have. Let's say you bid 3, but took 5. You get 32 points, but you also get 2 sandbags.
