Picture Poker

Picture Poker is a single-player minigame in Super Mario 64 DS and New Super Mario Bros. In the former, it is classified as one of Luigi's minigames; in the latter, it is classified as a Table minigame.

Gameplay
This minigame is a casino-style card game in which the player automatically bets coins that their five-card hand beats Luigi's. After being dealt their hand, the player can bet more coins and/or have some or all of their cards replaced with random cards from the deck. Luigi then, if need be, replaces cards in his hand (which appear face down to the player) with random cards from the deck. The hands are then shown. If the player's hand is better, they win a set number of coins based on both the rank of their hand and the number of coins bet ranging from a Pair (2x) to Flush (or five of a kind) (16x). If Luigi's hand is better, the player simply loses the coins bet. In the rare occurrence that a draw happens, the player gets their coins back.

The player is awarded Stars with each victory and is deducted Stars (if they have any) with each loss. The minimum bet is determined by the number of Stars in the player's possession; the bet increases by one for every five Stars, with a maximum of four at 15 Stars. If the player runs out of coins, the game is over and must be restarted.

If all opponents have the same hand, then these ranks determine who wins, in order from worst to best: Cloud, Super Mushroom, Fire Flower, Luigi, Mario, Super Star.

Multiplayer
The player can choose between three, five, or seven rounds. The player who goes first is chosen randomly. There is not any betting.
 * The winner (whose hand is the strongest) takes that many coins from the other players.
 * Flush/Five of a kind: 16 coins
 * Four of a kind: 8 coins
 * Full house: 6 coins
 * Three of a kind: 4 coins
 * Two pairs: 3 coins
 * One pair: 2 coins
 * With four players, the winner can receive up to 48 coins taken from other players, and for three players, it is 32. If none of the players have the above hands (Junk), then no coin exchanges occur.
