Blackjack

Blackjack is a text-based card game made in 2003 for the TI-83 Plus calculator by Cleod9 Productions and published by McLeodGaming. It is based on Blackjack, the popular card game of the same name.

Gameplay
The gameplay is virtually identical to that of the regular variant of Blackjack. The player faces off against a single computer-controlled opponent, and each player holds a hand of cards that only the holder of the hand can see. Each card has a numerical point value given by its number, where a two (2) card is worth 2 points, a three (3) card is worth 3 points, and so on. The three face cards, Jack (J), Queen (Q), and King (K), are each worth ten points. An Ace (A) card is worth either 1 or 11 points, and the player can choose which value to assign it. The player's total score is the sum of each card's point value, and the player with the most points at the end of the game without exceeding a total of 21 is the winner. If both players have the same amount of points at the end, or if both players' scores exceed 21, the game ends in a draw.

At the start of the game, the player is dealt two cards that display in their hand as their symbols. If the card is an Ace, the player can change its value from 11 to 1, or vice versa. Up to seven cards can be held in the player's hand, and only the first four of them display on the first screen, as the rest can be displayed by selecting "Rest of hand". In the Options menu, the player can then choose to perform one of the following actions: stay, which ends the player's turn with their current score; fold, which ends the player's turn and cancels their hand; and hit, which draws a new card into the player's hand.

After the player's turn ends, the computer player will perform their turn. Their hand is not revealed until after they end their turn, and both players show their scores. After the winner is revealed, the game ends.
