We are no longer supporting any new updates for Brainium games running on Fire OS / Kindle devices and have removed most Brainium games from the Amazon store. This means that Brainium games cannot be downloaded or transferred to any new Kindle / Amazon devices. If you are playing on an older Kindle / Amazon device with any Brainium games already downloaded, those games will remain playable as long as the app isn’t reinstalled or deleted.

* Please note: Due to Amazon rolling out new updates, some Brainium games may not be compatible with these new Amazon updates. If you purchased an ad-free version of the game, we are unable to issue a refund on our end. For all refund inquiries, please reach out to Amazon Support directly.

Thank you for understanding and we apologize for the inconvenience this may have caused!
