Google’s celebration of 10 Billion Android Market downloads marches on, and just like the last four days. there’s plenty of vastly reduced premium apps on offer. Google’s chosen some of the most loved apps on the Market and droped them to a ridiculous 10 cents/pence price. Today’s highlights, spotted early by the keen-eyed folks over at Reddit, include The Sims 3, quirky shooter Age of Zombies and SlideIt Keyboard, AKA “I Can’t Believe It’s Not Swype.”

The full list is as follows: Apparatus, The Sims 3, SlideIt Keyboard, Snowfall Live Wallpaper, Asphalt 6: Adrenaline HD, Season Zen HD (live wallpaper), Pano (panoramic camera), Drop7, Age of Zombies and Kids Connect the Dots. As usual the banner on the Android Market home screen isn’t up yet, so just use the links above as needed. Yesterday’s deals are still in effect at the time of writing, but they won’t last long!

The flurry of amazing price reductions has put a serious strain on Google’s payment servers, and a lot of Android users are experiencing problems getting their apps to register to their accounts. Luckily Google is feeling generous, and if you can’t purchase the apps right away, the company might just give them to you. If you’d rather avoid the whole mess, wait until the evening to download your new apps – it’s worked for me so far. While you’re waiting, be sure to check out Google’s graphical breakdown of its app achievement.
