Mario's Memory Madness
From the Super Mario Wiki, the Mario encyclopedia
Mario's Memory Madness was a browser game that was playable on the official Mario Party website. Unlike future promotional web games published by Nintendo, both Mario's Memory Madness and Wario's Whack Attack were made in Adobe Director instead of Flash and required the Adobe Shockwave 7.0 plug-in.
The gameplay is based on a memory game where the player has to flip and match pairs from a group of cards owned by Mario, depicting playable characters from Mario Party. The game is spread across several rounds; each round, the number of cards increases, and starting with the second round, cards occasionally change positions. The player earns five coins for matching a pair of cards and has a time allotted to finish each round. Coin Box-like mushrooms sometimes appear temporarily and move among the cards; while they are on the screen, the player earns ten coins for every match instead of the usual five. If the time runs out, Bowser steals Mario's cards, ending in a game over.
