To celebrate the Windows game's 25th birthday
Microsoft has challenged the world to a Solitaire tournament that will pit the company’s strongest players against the game’s biggest fans.
The tournament will launch on June 5 to mark the 25th anniversary of the game, which has long remained a permanent fixture of the Windows operating system.
The battle begins with an internal match among Microsoft’s employees. The winners will then lead a worldwide match against the general public, or as Microsoft put it in an official post: “you’ll be challenged to bring your best to defeat our best.”
