This eight-hour livestream event benefiting St. Jude Children's Research Hospital features 30+ top YouTube creators with a collective of nearly 300 million subscribers taking part in hours of games and fundraising challenges to support the lifesaving mission of St. Jude: Finding cures. Saving children.®

Creators from around the world will join The Game Theorists throughout the day including titans of YouTube giving Markiplier, MrBeast, ZHC, Mark Rober, Marques Brownlee and many more. The massive and growing list of talent will participate in a huge array of games and challenges, from Pictionary to "Let's Make a Deal" with a live virtual studio audience. Fundraising milestones will be marked with over-the-top stunts performed by MatPat and Stephanie, including receiving a "2020 haircut" from a robot, participating in the world's hardest workout, and performing larger-than-life science experiments. 

"We miss seeing our audience and creator friends so much in 2020, so we pulled out all the stops with the event this year to get as many of them together as possible," said Stephanie Patrick of The Game Theorists. "This community is so incredible and this year more than ever shows what a giving spirit there is with all these creators. We think we're creating a show unlike anything anyone has ever seen and the whole purpose is to raise as much as we can so that St. Jude can continue to provide world-class care for kids. These are the most important patients out there and childhood cancer doesn't stop for anything, including a pandemic."

The stream will be featured on YouTube's homepage and begin at 10 a.m. PST on The Game Theorists channel. Viewers can donate directly to St. Jude while viewing the livestream and fundraising totals will be reflected in real-time. Secret donation amounts will trigger special in-stream events and the completion of major fundraising milestones unlock activities for the creators or special appearances from important guests, including YouTube CEO, Susan Wojcicki.

"This year's show is 10 times the size of the one we put on last year when we raised $1.3 million for St. Jude," said Matthew Patrick of The Game Theorists. "We know it's been a tough year for everyone, but we have ambitious goals for this stream and want to make it a day everyone will be proud of, all to benefit the best of the best of causes, St. Jude. And yes, along the way, I'm going to get dunked, pied, slimed - you name it - every time we hit a donation milestone. That means the more you donate, the more ridiculous and fun everything gets."

The event is presented by YouTube Originals and brought to you by State Farm®, as well as an all-star lineup of sponsors: Ocean Spray®, Wizards of the Coast, Green Giant®, BarkBox, Blackhawk Network and American Airlines. 

GivingTuesday aligns with St. Jude Thanks and Giving, an annual holiday campaign that brings together corporate partners, generous consumers and celebrities to raise funds that help ensure no family receives a bill from St. Jude for treatment, travel, housing or food – because all a family should worry about is helping their child live.
