To play with the same Wynn Slots account from multiple devices, you need to connect your Wynn Slots account to the same Facebook account on all the devices.

While connecting to Facebook, please connect the Wynn Slots account where you started playing first, and then all your progress on that account will get saved to that Facebook account. After that, when you connect the same Facebook account to your Wynn Slots account on different devices, it'll fetch the same progress from the first Wynn Slots account.

Please note that the game doesn't support spinning from multiple devices simultaneously. So always close the game on one device before you start spinning from another one.
