Generally speaking for a single deck, 5, 10, and k together are a minimum bomb, and the rest of the 4 are 1 bomb, based on the previous player's play. If the player plays a single card, he has to follow it with a single or no card, or a bomb. The singles from smallest to largest are 3-k, ace, two and king. At the end of the game, the first player to play gets 25 points, and the last player to finish gets 25 points. Lots of the same color are in a set, and the cards indicate how many lots of the same color are needed for a set. For example, blue requires 2 cards, yellow requires 3 cards, black requires 4 cards, and so on.
