I have played several of the arcade games with no problems except with Simon. The game plays as it is supposed to until I made a wrong move. Upon making a wrong move the game switches me to the Undercroft sign in page. I played four consecutive games all with the same result. Using the back button returns me to the start screen of simon. I also tried logging out and then back in, with the same result.

I just tested it and got the same results, it is not compatible with the system. I have removed the game. Thank you!

It seems the "Weapons of mass destruction" high scores actually are the highest... time spend to get to the end of the game. In other words, the slower you are, the higher your number of seconds; the slowest player gets the highest score and wins the trophy.
