Sonic CD, considered by many to be the best Sonic game, is free for today only. The last time this game was free was in January. It has a great 4 star rating with over 800 reviews. It’s compatible with both the Fire TV and Fire TV Stick, but does require a game controller to play. If you haven’t picked up this game yet, this is a no brainer. Go grab it quick before it goes back to $2.99 tomorrow!
