Make your circle as big as you can without hitting any of the moving orbs. Once you’re done inflating, try to destroy all the orbs by capturing them within your circle in as few clicks as possible.

Cirplosion is one of the latest games posted to addictinggames.com. The game happens in two parts. In the first part, the strategy is to get your circle to be as big as possible. If your circle hits an edge or an orb, you lose a life and have to start over. Once you’ve stopped inflating your circle, it becomes the marker for the second part, where you have to destroy all the orbs. Wait until the most amount of orbs are inside your circle and zap them. Through all of this, you have a time limit to complete the cirplosions within.
Each level has more orbs, and allows you more cirplosions to capture them. I found the game pretty simple, but it can get difficult in the higher levels. Good luck!
