Here's another idea: give them some kind of "anti-medal":D - let them be happy:smile04:. You could deduct a huge number of points in the rankings - especially in a permanent one. Or, if not an anti-medal, at least just a huge label: I CAN CHEAT - when playing against me, save every day!:)

P.S. Although I must admit:o, I cheat regularly... in single-player, testing the map after completing the game:D :D :D - by the way, this is also a good way to develop some game skills (fair ones!), in particular, with the help of infinite turns, you can quickly clear the entire map and practice a lot of difficult battles, which you either haven't had time to do in online mode, or haven't done correctly!
