Can anyone tell me how people can complete 30 puzzles in the microsoft solataire collection...

Hi there,

Many thanks for your reply and I think you are right with your suggestion

They might be using exploits in the game to complete the puzzles, just a guess.

If all of the puzzles are completed at once it's possible that it was completed on another computer or installation of Solitaire, or even on a Windows Phone previously. Then, once the user logs into Solitaire on a new machine, it transfers the achievements
over.

Hi there,

Thanks for your reply, only thing is I have been practicing for nearly three years and still only reach number 4

If the completions are not legitimate then I would recommend taking up your concerns with the developers of the game. http://microsoftcasualgames.com/casualsuite/support/default.htm
