Humble Bundle has once again partnered with YouTubers The Yogscast to bring back its pay-what-you-want Jingle Jam game bundle for the holiday season.

While most of Humble Bundle's limited time offerings let purchasers decided how their cash is split between Humble, charity, and game developers, this festive bundle instead donates 100 percent of its proceeds directly to charity.

Working alongside Humble, game developers have come together to offer 25 total games for the month-long charity bundle, with each game being revealed advent calendar-style between the start of December and Christmas.

No matter the size of the donation, bundle purchasers are able to choose which of the eight supported charities their cash will benefit. The funds raised through this year's event will support SpecialEffect, Wallace & Gromit's Grand Appeal, Whale and Dolphin Conservation, Mental Health Foundation, Save the Children, International Lesbian, Gay, Bisexual, Trans and Intersex Association, and Cancer Research UK.

Last year, the Jingle Jam sold 86,589 bundles and raised $2.6 million for charities like the Mental Health Foundation, ILGA, Whale and Dolphin Conservation, Cancer Research UK, GamesAid, and SpecialEffect.
