Sometime in February 2016, Miniclip added a new functionality to Agar.io. It will allows you to win a few coins without paying. It can be accessed by clicking the green "Free Coins" box on the left side of the screen, under the level bar. You have three ways of winning free coins:
- Hourly Coins: the first option, clicking it will immediately add 20 coins to your account. However, you can only select it once per hour.
- Video Coins: the second option, clicking it will show you a video (usually an advertisement or a film trailer), you'll win 10 coins after watching the video. No time limits.
- Offer Coins: the third option, clicking it will lead you to a window containing link to various offers. The reward is very variable, most offers will gain you 100 to 5,000 coins.
