Description

From the listing uploaded by “catappult”.

Catch bubbles, reach new highscores, annoy your friends. Easy. Open circle is very simple. Click on the screen, and the circle changes rotation. Try to catch as many bubbles as you possibly can. This app contains advertisment so I can buy beer, lock myself up in my room and make more app's like these, where you are going to hate yourself as a player for playing it. Thanks for playing Open circle!

Open Circle 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 the Open Circle APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Unknown. After downloading, check that the file's MD5 is 53e733818e17118c2f3380894fd3a69c.
