Amazon's Prime Day kicks off on Monday, but a number of deals are already available right now on Amazon. If you're a gamer, the best deal is all the free PC games Twitch (which is owned by Amazon) is giving away for free between now and July 18. All told, 21 free games will be available for Prime members in July.

The availability windows vary depending on the game, but today you can download 10 games for free. Don't put off grabbing them, because one game goes away every day this week. If you haven't gotten them yet, you've already lost out on games like Pillars of Eternity: Definitive Edition and Battle Chef Brigade. But even if you've missed some of the free games, many more lie ahead.
