First of all, you have to make sure you are logged in with the right account. Use the "Login" button located in the "Settings" screen (the mechanics room inside the station).

After that, go back to the play area and use the map selector.

On iOS only: if your maps are still not unlocked, use the "Restore Purchase" button.

You re-installed the game and would like to restore your expansions (iPad or iPhone)

First of all, make sure that you are using the same Apple ID as before. Apps and expansions are tied to your Apple ID, so it is important to use the right one. This can be verified by going to Settings » Store: your Apple ID will be displayed there and you can switch to another one if you need to.

Ticket to Ride users: we also strongly advise that you connect with your Days of Wonder account in the app. Since version 2.1, this will save a backup copy of your expansions activation in your Days of Wonder account, which will avoid headaches in case of problems with the App Store. To do so, go to the Settings screen (on the main screen, click on the top right to access your account screen) and push the Login button. Then follow the instructions.

Restoring your expansions:

1) Start your Days of Wonder game and find the "Restore Purchases" button:

2) Push the "Restore Purchases" button and enter your Apple ID password. This will restore your expansions.
