Xbox is celebrating the holidays with a 99 cent sale on several popular Xbox LIVE games for Windows Phone. And given that I actually own all of these games already, I can tell you that there are more than a few top-notch titles here. This is the time to buy.

Each of these games runs on Windows Phone 7.x as well as Windows Phone 8. And they’re all kid-friendly, too, so they’re ideal choices for Kid’s Corner, which I wrote about recently in Windows Phone 8 Tip: Share Your Phone Safely with Your Children.

Here’s the list:

Contre Jour

Blurring the lines between games and interactive art, Contre Jour welcomes you to a hauntingly beautiful world shaped by the interplay of light and darkness.

Doodle Jump

Leap from platform to platform, finding your way higher and higher using brilliant power-ups like springs, propeller hats, and jet packs.

geoDefense Swarm

With dizzying vectorized visuals, vexing challenges and highly kinetic gameplay, the thinking man's tower defense game returns.

iStunt 2

Hit the slopes for some serious shredding and perform impossible stunts, dodge deadly saws and do incredible jumps in a world where gravity laws have been broken.
