It added 450,000 new users on Christmas Day alone - the largest day in its history, and up 184% on its daily average. Over the four days, OpenFeint signed up 1.4 million new users.
"We always expect a spike in downloads over the holidays as more people put games on new mobile devices,” says CEO Jason Citron.
"This year showed an impressive increase as our user acquisition increased almost twofold around Christmas. New devices and free time make for more mobile gaming over the holidays."
