The web3 mirror is an official version of Castle Age that allows player to play through a browser without needing to be on Facebook. To use this version of Castle Age, the player must sign up through the new Crusaders of Castle Age form, and create a Castle Age Universal account.

Accessing Web3

The URL for the web3 portal is Here, you may log in with your universal account.

Signing Up for a Universal Account

No matter what platform you register on, a Universal Account requires the player to have an email address.


To sign up for Crusaders through Facebook, your Player's LV need to be at least Level 3. Once you reach that level, the Crusaders link will appear under the Home submenu on the navigation bar. For convenience, it is also linked here. Note that you must be using https in order to sign up (though Castle Age should be forcing https use at this time). Once there, sign up with your email address, and create a password that you will be able to remember. You will be sent a confirmation email, and upon confirming, you will be able to access web3 with your Universal Account.


To sign up for a Universal Account through iOS, select the More menu from the bottom toolbar, and scroll down to the Castle Age Account button. From there, you can create your castle age account by signing up with your email and creating a password. Once you receive a confirmation email with a code, you can enter that code and activate your account.

Benefits of Web3

Playing through web3 (or the similar mirror, web4) allows players to avoid many bugs that come up because of Facebook issues, and generally has fewer problems than the Facebook version. It is also the only way to play the full version of Castle Age on a mobile phone, as attempting to play through Facebook will redirect the player to the iOS version otherwise.

One benefit of using the web3 interface is you can invite other facebook players using army codes instead of having to add them to your friendlist before you invite them.

For iOS players, web3 is the only way to participate in several features, mainly Conquest Duels and all Festival activities (Feats, Towers, and Duel Champion).
