Mario Undōkai

Mario Undoukai (マリオ運動会, Mario Undōkai, lit. "Mario Sports Festival") is a Mario arcade game released in Japan only, in 1993. Like Buzzing Mario, very little is known about it. It was published by Banpresto. The game is a dancing game geared toward small children. It is one of the only two dancing games in the Mario series and is very similar to the other one, Dance Dance Revolution: Mario Mix, but there are 2 neutral foot spaces and no 2-player mode.

Gameplay
Once a coin has been inserted, the player must choose from one of three games, all of which require the dancepad and the lone button. The left selection appears to be a simple flag matching game, while the right selection is unknown.

The top selection is a more athletic based set of games that involve Olympic style events. The first of these is a 100m sprint against Ludwig, Morton and Bowser. Koopa Troopas are the judges, while Monty Mole holds the sign or the events. The second event is a Yoshi race against Luigi and Peach. The 3rd event is a 110m hurdle race against Ludwig, Roy and Larry. The results screen appears to be randomized, as Wendy appears even though she didn't compete.

After the results, a trading card is distributed from the machine, while Mario invites you to play again some time.
