Mickey's Ultimate Challenge is a puzzle game for the Super NES, Game Boy, Sega Mega Drive/Sega Genesis, Sega Master System, and Game Gear. The Master System version, released in 1996 was the last game ever released for that console. All other versions were released in 1994. It was rated for all ages, aimed toward younger children, and was designed for only one player. The design is simplistic as Mickey can only perform three things: walking, jumping, and going through doors. There are five major challenges, a segue, and a final challenge. It has met with mixed reviews from gaming magazines.

Mickey's Ultimate Challenge is a puzzle game where players must complete challenges to beat the game. Players must go through a series of challenges in various rooms of the castle in order to collect magic beans and items.

In Sorting Books, Books are floating up and down in the library of the Beanswick castle and Mickey must sort them in alphabetical order by jumping on them. Depending on difficulty, there are various numbers of books to be sorted and different patterns for the books to float in. Only a portion of the alphabet must be sorted. Once the books have been sorted, players receive an item from Horace Horsecollar. In Moving Potions, Mickey is transformed into a tiny size and placed on a chess-like game board. Potion bottles are on this board, as well as block obstacles that must be maneuvered around. The potion bottles are to be pushed into a magic mirror on the board. In harder difficulty games, there are more boards to play in increasing difficulty. Once all potions have been collected, you return to normal size and receive your item from Donald Duck (dressed like a wizard).

Picture Matching is a timed, memory challenge. Mickey must dust off portraits hanging on the castle walls in matching pairs. Basically, it's the matching card game. He must complete this task before the lights in the castle dim to darkness. Depending on difficulty, there are more or less pictures. For challenges with more pictures, more time is given. He is armed with a feather duster and sliding ladder. Match up all the pictures before time and light run out to receive item from Daisy Duck as a princess.

Playing the Pipes is another memory game. Several pipes light up and make different noises in a pattern that builds every turn. Mickey must listen, remember, and repeat what he heard. He can do this by jumping on the top of the pipes and playing the notes back in the proper order. The pipes only play one melody, adding one note after every time Mickey successfully completes the previous one. Difficulty of game play determines the length of the melody. Players must play all the right pipes to receive the item from Huey, Dewey, and Louie. In Guess the Tools, Goofy wants Mickey to guess what tools are in his toolbox. Mickey has seven attempts to successfully guess the tools and their order inside Goofy's toolbox. After each guess, a clue appears telling players how many and which tools you guessed in the correct order. In easier games, the tools turn red or green to denote correctness. In more difficult games, a small quartered square of red and green pieces tells Mickey which ones are right. Players must correctly guess what is in Goofy's toolbox to earn an item from Goofy.

Exchanging Items is the segue of the game. The items Mickey collected were of no importance to their previous owners, but would serve useful to others in Beanswick. Mickey must go back to all of the others in each challenge and give them the item that suits them. In return for each correctly placed item, Mickey receives a magic bean. Only after retrieving all five beans can Mickey use them. After returning the items to their respective owners, Mickey visits the well. The annoying rumbling occurs again and Mickey throws his beans near the well. Suddenly, a giant beanstalk grows straight up into the clouds. A curious Mickey climbs the beanstalk into the clouds and encounters a giant. The giant is sound asleep and snoring. This massive snoring is the cause of all the trouble for Beanswick. There is a scrambled picture of an alarm clock floating next to the giant. Mickey must unscramble the picture by sliding the pieces and wake up the giant. After Mickey wakes up and talks to the giant, the troubles in Beanswick are solved.
