Mini Mario & Friends: amiibo Challenge

Mini Mario & Friends: amiibo Challenge is a downloadable game for the Wii U and the Nintendo 3DS systems. It was released in Japan on January 28, 2016, and will be released in April 2016 internationally, making it the only installment so far in the Mario vs. Donkey Kong series to not be released in North America first. In North America, it will be available for early access between March 25, 2016 and April 27, 2016, with the purchase of any amiibo figure at Amazon, Best Buy, or GameStop. It is the seventh installment in the Mario vs. Donkey Kong series and the first to feature amiibo support. New toys are featured in the game, such as Mini Rosalina, Mini Bowser, Mini Bowser Jr., Mini Yoshi, Mini Diddy Kong, and Mini Spek, while returning toys include Mini Mario, Mini Luigi, Mini Donkey Kong, Mini Peach, and Mini Toad.

Gameplay
The main game is largely similar to previous installments in the series, in that the player controls a Mini Toy trying to reach the end of the stage. By scanning a compatible Mario series-related amiibo, the player can receive the corresponding toy to play as, while the Mini Spek is received by scanning any other amiibo. Each Mini Toy (with the exception of the Mini Spek) has a special ability that allows it to clear stages easier. At the end of each stage, players are given a score based on their performance, and by clearing it with a high enough score, the player earns a Gold Trophy for that stage.

Within certain main stages are amiibo Doors, which can only be accessed by the corresponding character on the door and unlock special stages themed around that character. Some stages also feature amiibo Tokens, which don't work in any other game and can only be obtained by using the abilities of the amiibo on the token.

Mini Toys
Unlike in previous games, each of the Mini Toys have their own unique special abilities corresponding to them.

Trivia

 * Mini Pauline is the only mini not present in this game, as there is no Pauline amiibo.
