There are millions of free apps available on the Play Store, and many of them are pretty great. But there are also millions of paid apps that don't always get the attention they deserve.

Now, Google wants to highlight a few of those paid titles by offering a free app or game of the week. The first one is Card Wars — Adventure Time, a lighthearted card trading and battle game that usually runs for $2.99, but this week is going gratis.

Like Apple's version of the same, it appears Google will highlight a single title each week, and chances are it will be a paid game that also has in-app purchases. That benefits both Google and the developer, since it gets a chance to add millions of new users and ramp up revenue.

This isn't the first time Google has given away paid apps for free. It started the practice in its then-nascent Family section back in 2015, but that particular enterprise seems to have faded away for this more broad version.
