Last week saw the arrival of Xbox Music and Xbox Video to Windows Phone 8; this week brings some games. If you're a Windows Phone 8 user yearning for some addicting time-sinks, three games every Windows user is probably very familiar with has just arrived: Solitaire Collection, Mahjong, and Minesweeper. I'm sure every person with an office job has ignored work at one point or another for a game of Solitaire or Minesweeper, right?
Not only are the games redesigned for touch controls, but since they're also "Xbox games", you can earn achievements and compete with friends and on leaderboards. They also have the ability to be paused and resumed on any Windows Phone, PC, or Tablet.
