Announced as part of Ubisoft's financial report for FY16, the company has revealed that Hungry Shark World has done 10 million downloads in six days.
The latest game in the popular Hungry Shark franchise from wholly-owned studio FGOL, it's a simple arcade game which has players unlock big and bigger sharks as they munch their way through creatures of the sea.
Previous game Hungry Shark Evolution generated over 80 million downloads.
Can it sustain?
But more than the downloads numbers, Ubisoft will be encouraged by the game's top grossing performance.
In the US iPhone chart it peaked at #34 and currently sits in the #50 position.
Of course, given the lack of long term retention mechanics currently in the single player game, what will be interesting to see is how long the game can maintain this position.
More generally, Ubisoft said it mobile and handheld gaming according for 6% of its FY16 sales - around $95 million.
