Test your speedrunning skills in over 150 challenges. Each challenge relives a memorable moment from one of 13 NES games, including classics like Super Mario Bros. 3, The Legend of Zelda, Donkey Kong, and Metroid.

See how quickly you can blaze through the first level of Super Mario Bros. or how fast you can gobble up an enemy in Kirby’s Adventure. Hone your skills and see if you have what it takes to be a champion!

Jump into World Championship Mode and see how your best times match up against those of other players of varying skill levels. No need to master entire games – anyone can become a Nintendo World Champion if they can conquer these “byte-size” challenges! Record your best time in the five weekly challenges and see if you can emerge as the fastest player of the week.
