blackjack
the players' object is to win money by creating card totals that turn out to be higher than the dealer's hand but do not exceed 21 ("busting"/"breaking"), or alternatively by allowing the dealer to take additional cards until he/she busts. on their turn, players must choose whether to "hit" (take a card), "stand" (end their turn), "double" (double wager, take a single card and finish), "split" (if the two cards have the same value, separate them to make two hands) or "surrender" (give up a half-bet and retire from the game). number cards count as their natural value; the jack, queen, and king (also known as "face cards" or "pictures") count as 10; aces are valued as either 1 or 11 according to the player's choice. if the hand value exceeds 21 points, it busts, and all bets on it are immediately forfeit. after all boxes have finished playing, the dealer's hand is resolved by drawing cards until the hand busts or achieves a value of 17 or higher (a dealer total of 17 including an ace, or "soft 17", must be drawn to in some games and must stand in others). the dealer never doubles, splits, or surrenders. if the dealer busts, all remaining player hands win. if the dealer does not bust, each remaining bet wins if its hand is higher than the dealer's, and loses if it is lower. if a player receives 21 on the 1st and 2nd card it is considered a "natural" or "blackjack" and the player is paid out immediately unless dealer also has a natural, in which case the hand ties. in the case of a tied score, known as "push" or "standoff", bets are normally returned without adjustment; however, a blackjack beats any hand that is not a blackjack, even one with a value of 21. wins are paid out at 1:1, or equal to the wager, except for player blackjacks which are traditionally paid at 3:2 (meaning the player receives three dollars for every two bet) or one-and-a-half times the wager. many casinos today pay blackjacks at less than 3:2 at some tables; for instance, single-deck blackjack tables often pay 6:5 for a blackjack instead of 3:2.

match-three games are np-hard when generalized to an n × n playfield and played such that the player knows in advance all the tiles that will appear, with no random chance involved. in particular, it is np-hard to determine:









































bullet::::- is there a sequence of moves that allows the player to match a specific tile?









































bullet::::- can the player get a score of at least x?









































bullet::::- can the player get a score of at least x in less than k moves?









































bullet::::- can the player cause at least x tiles to match?
