A free browser-based flash game inspired by the Dungeon Crawler Carl book series, titled "Mama's Night Off," has been released online, marking the franchise's first playable game. It arrives during a busy period for the series, which recently had a live-action television adaptation confirmed and a tabletop role-playing game due for release in December 2026.

The game, created in collaboration with confectionery brand Maeve Chocolate, features the character Princess Donut firing magic missiles at falling cherries, with sound effects voiced by audiobook narrator Jeff Hays. It launched roughly a week ago and was announced on the Dungeon Crawler Carl subreddit, primarily to promote Maeve Chocolate's new "Virgin Dirty Shirley" bar, itself inspired by Princess Donut's favourite drink. The forthcoming tabletop RPG, developed with Renegade Studios, has proven highly popular, having raised significant funds through a Backerkit crowdfunding campaign and remaining a strong seller on pre-order via Amazon.
