Amazon is celebrating the fourth birthday of its Appstore by offering Android apps worth $130 for free until March 22. All the apps that have been made free are listed under ‘Free App of the Day Bundle’ category.

At the Amazon Appstore, 34 paid apps are now available free of cost. It includes 16 games, and various apps for productivity, utilities, photography and more. The apps can be downloaded and installed on Android smartphones and tablets, Kindle Fire devices and the recent BlackBerry smarpthones. Even though Amazon has not released an official statement about the date on which the offer will expire, NDTV assumes that offer will finish on March 22.

The games section includes various free games that are usually priced from $1 to $10. Some of the listed games include Five Nights at Freddy’s 2, Cut the Rope, World of Goo, Kingdom Rush Origins, Ruzzle, The Hidden World, Unpossible and more. Some of the other freed up apps include Reading Trainer, Atomus HD, Cross DJ Pro, G-Stomper Studio, Business Calendar, HanDBase Datebase Manager, OpenDocument Reader, Folder Sync and more.

Amazon Appstore usually includes those apps that are banned from the Google Play Store. Hence, the apps listed above are unavailable there, reports Phone Arena. However, in order to install the apps, users will have to sideload them on their devices. Amazon has a link that explains how to install the apps on Android devices.
