Chain reaction APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is Chain reaction free?

The APK is free to download, but the game offers in-app purchases through Google Play.

Is the Chain reaction APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 4d772d8aec6c7451248595593f7b2575.
