@rsmallwood it is a server side setting so they don’t need to update the client in order to change it.
As best I can tell there are multiple versions of the tower, i.e.
* Some users can access the tower once per day, whilst others seem to be able to access it once every 12 hours and even some that can access it every hour
* Some users have a max floor of level 30 where they can win a fancy hat, yet others have to reach level 90 in order to get a fancy hat
* Some users only have 3 cards in the tower, whilst other users have 4 cards
Now I can only guess that they are breaking players into groups based on where they live. So as I live in Australia I get a 90 floor tower, that I can only play once per day, and it contains 4 cards per floor….where as someone in the US may have a variation of that, and someone in Norway may have a different variation again.
Again I am guessing, but I imagine they are trying all of the different options across all of the different groups/regions to figure out which options get the users (you/me/everyone that plays AB2) playing, and most importantly for Rovio spending money.
