Dear Esther (opens in new tab), survival roguelike The Flame in the Flood (opens in new tab) and indie shoot-em-up Downwell—which was so good that the creator was promptly hired by Nintendo (opens in new tab)—are among the games that Twitch Prime subscribers can claim on their accounts this month, Twitch has announced.
Pikuniku (opens in new tab), a delightful dystopian puzzler that came out last month, is also currently free for Twitch Prime susbcribers, and has been since last week. Like the other games, you have until the end of February to claim it here (opens in new tab) (and judging by Philippa's review (opens in new tab), you really should).
Anyone with a Twitch Prime subscription, included with Amazon Prime membership, can also grab the Draknek & Co Puzzle Collection, which contains a trio of clever puzzle games: Sokobond (opens in new tab), A Good Snowman Is Hard To Build (opens in new tab) and Cosmic Express (opens in new tab).
Once you claim the games, they'll be waiting for you on the Twitch desktop app, which you can download here (opens in new tab).
If you're already an Amazon Prime member, you can link your Twitch Prime account here (opens in new tab). As well as free games, Prime membership gives you one channel subscription to use every month, exclusive emoticons and in-game loot.
