Amazon is gearing up for Prime Day, a major sale event for Prime members. Prime Day doesn't officially begin until July 16, but a number of deals are already available right now. If you're a gamer, the best deal by far is the truckload of PC games Twitch (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. Make sure to grab them quickly, because one game goes away every day this week. Yesterday, for instance, was the last day to download Q.U.B.E. 2. But even if you've missed out on some of the free games, many more lie ahead.
