Solitaire has changed a bunch since it was first released on May 18, 1990. In addition to the classic game, there are now others like Klondike, FreeCell, Spider, TriPeaks, and Pyramid.
These games, along with their cousins, Minesweeper and Hearts, have long been known as productivity wasters.
Solitaire was actually removed from Windows 8 - you had to download it from the Windows store.
But it's making a come-back in Windows 10, along with Minesweeper.
Plus, Microsoft is also giving Windows 10 one of the most addictive, biggest productivity waster games of all time, Candy Crush
