Hello,
Thanks for your taking part!
The correct answer was 603 games.
I can see that most of you were optimistic. Here was a simple way to get close to the answer:
At any given time, there are about 2 games of Lost Cities running in the inn. Each game takes about 4 minutes. It means there are about 30 games of Lost Cities per hour or 720 per day.
Congratulations to Vreni S. that wins a week of Magic Potion. I hope you will enjoy it, Vreni!
Have fun all! We will certainly be back with these contests some day. Watch this space!
