For Pi Day, Microsoft doesn’t want you to spend all your money eating only pies or geting mind blown because the sequence is cooler this year (3.14.15 at 9:26:53 AM is same as 3.141592653 = π). To celebrate Pi Day which also happens to be Albert Einstein’s birthday Microsoft wants you to get the new digital gift cards with the Pi Day theme by downloading the Digital Gift Cards app for free from the Windows Store and Windows Phone Store. To top the icing on the cake, for 24 hours today, you’ll be able to buy a 12-month pass to Xbox Music for just $31.41 (regularly $99) from the Microsoft Store. The offer is good for new subscriptions and renewals of existing subscriptions. While you eat you pie in honor of Pi Day, you can grab the new Einstein Brain Trainer HD app that comes with 30 activities to stimulate your mind. The app is on sale for half-off at the Windows Store for $2.99 and $1.49 at the Windows Phone Store.
