The game features a ‘Picture Poker’ mini-game, in which the player bets against Luigi in a casino setting. It provides a guide to the ranking of different cards (which feature pictures rather than a real-life deck) and hands (three of a kind, full house etc.). The player has the opportunity to bet more coins and swap cards before the hands are revealed. There is also a roulette game, in which the player receives simple instruction on how to play and bet on the wheel.
Other issues
The majority of the game is not represented by this casino gameplay. It features cheerful environments, child-friendly characters and cartoonish reactions when Mario and co. run into obstacles and enemies.
