Mario vs. Donkey Kong is a video game series that is a spin-off of Mario and Donkey Kong and focuses on puzzle-solving. This series marks the return of Pauline and continues the competition between Mario and Donkey Kong. The naughty gorilla stole all of the Mini-Mario toys from Mario's toy factory, and it is now your task to retrieve them from the six different planets where they were hidden. In certain stages, you'll be scratching your brain over the puzzles, and then in the next level, you'll be responsible for guiding the Mini-Marios to safety; the final level of each planet pits you against Donkey Kong himself!
