Microsoft marks 25 years of Solitaire with a tournament

Microsoft Solitaire, aka Windows' biggest productivity killer, is turning 25 this year -- and the team in Redmond is going to mark the occasion in style. The company is starting with an internal tournament this month that will determine who rules the roost within its own ranks. You'll get to participate in June, when the company releases the tournament's challenges to the public through its Solitaire Collection. If you've spent years mastering the art of ordering cards, your finely-honed (if not exactly practical) skills are about to pay off.
