For those not familiar with Red Stripe Deals, every week three Windows Phone titles will be discounted and identified by a red stripe around the icon. You'll have one Xbox Live title, one game, and one app discounted. The discounted pricing only lasts a week.
Monster Pinball HD is now $.99 (no trial version) and you can find it here in the Windows Phone Store. Sonic CD is discounted to $1.99 (you can find it here) and Polyglot, a language translator, is now $.99 (you can find it here).
