Which Characters Should You Unlock First?

If you just want to play casually, unlocking characters through regular matches is your best bet. Diddy Kong and Birdo are solid choices that you’ll get naturally.

But if you’re after the more unique characters like Dry Bowser or Petey Piranha, be ready to put in some serious time with the challenge modes.

The tournament unlocks are pretty simple too. Just pick your favorite partner for doubles and work through the cups one by one.
