Markiplier is one of the most popular games channels on YouTube, with 18.8 million subscribers and 8.4bn lifetime views. Founder Mark Fischbach is using that position for good, too.

His latest charity livestream, on YouTube for Save The Children, more than doubled its $200k target. The event raised $422k according to industry site Tubefilter.

The livestream saw Fischbach playing physical games like Jenga and Cards Against Humanity, with a twist. Fischbach and his collaborators played Jenga while wearing muscle stimulators; did yoga while blindfolded; and hunted for Easter eggs while wearing a shock collar.

The videos proved popular: 747k views so far for the final Cards Against Humanity game, which was made available on-demand after the initial live stream. The other videos from the event are also comfortably into the mid-hundred-thousands views-wise.

It wasn’t Fischbach’s first charity fundraising event. In 2015, for example, his GoFundMe campaign raised $82k for the Depression and Bipolar Support Alliance.
