I think this was a great event.
I managed to get a level 10 world's fair in all 12 live cities where I did the event, even though I missed logging in for free scrolls on 4 days during the event due to work.
Luck played a very minor part in getting the idols, in nearly every world I collected almost identical numbers of them.
The only part that luck played was in the number of daily specials I collected, which did vary considerably from world to world.
With this event inno gave us a game of skill and tactics to play, where efficient use of tools was enough to ensure the full main prize if that is what you chose to concentrate on.
Can we have more events along these lines please.
