In smash bros, turn the launch multiplier all the way up and turn on sudden death mode so everyone starts at 300%.

Go to one of a few levels (the underground area of Hyrule Temple works, the underground area of Skyworld is better, but it’s best if you make a custom stage)

Getting hit once will send you bouncing around the screen! You only ever loose if you get unlucky. It’s hilarious, and we call it “Pinball Mode”. I’ve made a couple custom stages to improve on the experience.
