Angry Birds Space hit 50 million downloads in 35 days, making it the fastest growing mobile game yet, according to developer Rovio.
The bird-flinging title is currently available on iOS, Android, PC and Mac, with ten new levels recently released for the mobile platforms as part of a free update.
"We extend our deepest gratitude to all fans of Angry Birds everywhere," Rovio said on its blog.
"While numbers like this certainly say something about the popularity of Angry Birds, for us the main goal is to keep creating fun new experiences that everybody can enjoy."
The studio went on to tease "plenty more surprises", adding: "There's only one conclusion to draw: something even bigger is on its way."
Earlier this month Nintendo design legend Shigeru Miyamoto said he wished he'd invented Angry Birds.
