I'ts not a question of cheating because there is nothing to win, you only get the bracelets for achievements within your group and not for being in the top hundred. To understand what's going on here you should make a list of the top twenty and their times over the past two or three months, also visite the FaceBook Site for Microsoft Solitair Collection because there you will find the answer.
Of course there is stilll cheating even though there is nothing to win! People like to see their name in the top 10 or whatever their goal is. If it wasn't a big deal people wouldn't CHEAT and make bots to get ridiculously good times! If there is ANY ranking in a game, then using bots or multiple accounts is CHEATING. And it can take away from the fun for SOME people, while others just don't mind at all. BOTH reactions are fine, and I believe that microsoft could absolutely show SOME interest in resolving this problem by grouping players together by skill level. People who regularly score under 30 minutes for 30 games should be in groups together and away from other players. People who regularly beat the Events in under 1 hour can be grouped together, and so on. How hard would that be?!
