There is also an FAQ stickied at the top of this forum.
Yes, that is a walkthrough, but it does not contain a list of castle upgrades and what you get at each level.
I see that my links were removed. Just do a google search for "Tapped Out Clash of Clones wiki"
Castle Levelling Up
When the player taps on a castle they are presented with that interface. It tells them what level the Castle is currently on, and how much Elixir it will cost to level it up. It also shows the amount of nerds it generates per 2 hours. Upon levelling up, all castles display fireworks.
After a certain decoration for a castle is unlocked after levelling up, it is available in the store to buy for TO Elixir.pngElixir and Donut Tapped Out.pngDonuts. (Prior to a small update on August 27, 2014, Walls, Towers and Gates for a castle would be available after the castle surpassed Level 10.)
