Mickey's Ultimate Challenge is a puzzle game released in 1994 by Hi-Tech Expressions. The game was released for Game Boy, Game Gear, Sega Genesis, Sega Master System and SNES.
One night, when Mickey (or Minnie, depending on which character you choose) was reading a book, he wondered what it would be like to live in a distant land. When he fell asleep, he woke up in the Kingdom of Beanwick, which is constantly plagued by earthquakes. Then he offers help in solving the mystery of earthquakes. Each quest is a different puzzle. After completing all quests, Mickey or Minnie must exchange the acquired gifts for the appropriate characters. Giving the right items to the right characters will give Mickey or Minnie access to the last puzzle and character.
