Asphalt 6: Adrenaline (Kindle Fire Edition) ($6.99). For old-school purists looking to log serious hours behind the virtual wheel, this app is worth its above-market-average price. The graphics alone are stunning, proof that the Fire is capable of riding alongside, if not quite exceeding, the iPad and Sony’s PSP. What you get in Asphalt 6 is plenty: dozens of car and track options (more of which open up as you rack up victories), escalating racing challenges (some races cut the laggard after each heat), and multiplayer options (either against online opponents or other Fire-owning pals).

Your Fire serves as a steering wheel—tilt it in the direction you want to turn. Acceleration is managed automatically by the app in the factory-set steering mode. Or, to handle acceleration (and other controls like braking) manually, switch by opening up the onscreen Options menu. One sizeable downside is worth noting. After the app’s initial 2.4 MB download, the opening screen informs you that another 514 MB of graphics need to come on down to make this thing fully functional. Oddly, there’s no mention of that on the game’s Appstore page. If you’re up for carrying such a big load, by all means spend the money, and the 20 minutes it takes to download those extras. Then grab your driving gloves and hit the track.
