Nintendo usually releases a Mahjong video game for their consoles, and the DS is no exception with two versions. This new entry in the series is the first to have Mario characters, but other than that the game doesn't bring much to the table in terms of new content. For beginners, a Lakitu will explain to the player how to play the game. In it, you try to have to get a suit that is better than that of your opponents.
There are a variety of playable characters all from the Mario universe. From the start, you'll be able to play as Mario, Luigi, Yoshi, Toad, Princess Peach, and Donkey Kong. As you progress through the game, however, you'll unlock more characters including Wario, Waluigi, Bowser, Princess Daisy, Petey Piranha, Bowser Jr., and Toadsworth.
The game features even more opponents to face off against. The enemy characters vary in difficulty, and among the opponents are all of the above playable characters. The opponents that aren't playable include Goomba, Shy Guy, Koopa Troopa, Boo, Diddy Kong, Birdo, Hammer Bro., and Toadette. It should be noted that a character will not be an opponent if it's the character the player has chosen to play as. For example, if you choose to play as Mario, you will not be able to face off against Mario.
