Nintendo is holding open tournaments for its two major competitive games, and they’re open to players of all skill levels (who are at least 13 years old). Those who make it through the qualifying online rounds will participate in the finals at PAX East.
To participate in the Super Smash Bros. Ultimate tournament, you can head here to register. To participate in the Splatoon 2 tournament, you can head here to register.
The Smash Bros. qualifiers are spaced out by region and begin on February 2. Splatoon 2’s tournament is a little simpler as it takes place on February 10 with a follow-up qualifying round happening on March 2. You can find more details here.
