With just over a month until E3, Nintendo revealed their plans for the week of the expo, which include special events, game demos, and a return of a major competition.

The Nintendo World Championships will return for the first time in 25 years. Previously held in 1990, the Championships were a Nintendo-promoted competition of games including Super Mario Bros., Red Racer, and Tetris. Starting May 30, consumers can visit select Best Buy locations for qualifying tournaments. Alongside competitors from Nintendo, winners from each regional qualifier will meet on June 14 in Los Angeles for a Nintendo game competition to determine who will be crowned the 2015 Nintendo World Champion. Can you beat Reggie?

The company also revealed their major news will again be revealed via a digital event on Tuesday, June 16 at 9 a.m. pacific. Nintendo will show off details about various games and experiences (at the same time as Square Enix. Awkward?)

Nintendo Treehouse: Live at E3 2015 will give fans a closer look at products shown off during the event. Gaming experts will be available for those on the floor, and live streams will be available for those watching from home

The upcoming Wii U exclusive, Mario Maker, will be available for fans to try out at participating Best Buy locations on two days during E3 week. On Wednesday, June 17, players can try their hand at the game from 4-9 p.m. and on Saturday, June 20 from 12-5 p.m. Those who attend will receive a 30th anniversary Super Mario Bros. pin while supplies last.

“Whether you’re tuning in online or joining us at the show, we want to include fans of all ages this E3 with an innovative and nostalgic focus on fun,” said Reggie Fils-Aime, Nintendo of America’s President and Chief Operating Officer. “I’m especially eager to bring back the Nintendo World Championships and to crown the 2015 Nintendo World Champion.”
