To play with the same Wynn Slots account on multiple devices, you need to connect your Wynn Slots account to the same Facebook account or the same email address on all the devices.
When connecting to Facebook or an email address, please connect to the Wynn Slots account where you started playing first. This will save all your progress on those accounts. After that, when you connect the same Facebook account or log into the same email address in the Wynn Slots game on different devices, it will fetch the same progress from the original Wynn Slots account.
Please note that the game does not support spinning from multiple devices simultaneously. Always close the game on one device and remove it from the background before you start spinning on another device.
