A new “Only on the App Store” promotion has made a number of top iOS apps and games free from iTunes. Infinity Blade II, Where’s My Water?, Badland, Tiny Wings for iPhone and iPad, Superbrothers: Sword and Sorcery EP, Day One, Over, Barefoot World Atlas, Traktor DJ for iPhone and iPad and more are all currently free — Traktor DJ notably normally sells for $20.

The apps have likely gone free to mark the upcoming fifth anniversary of the App Store. It’s unclear how long the apps will be available for free, or if other apps will be made free at some point. [via The Verge]
Update: Apple has noted the apps are free for a limited time as part of “5 Years of the App Store.” A timeline of App Store milestones can be viewed within the App Store. The promotion also includes How To Cook Everything for free, in addition to the apps listed above.
