You can play the game on multiple mobile devices using Facebook login.

Note: this option is not available on Windows and Mac.

There are a few things you should know about synchronization when you play on two or more devices:

• You must have the latest game version on both devices
• Both devices must meet the minimum system requirements.
• Don't play the game on two or more devices simultaneously. Don't play the game if it's open on your other devices. Don't switch between devices quickly. Otherwise it may cause serious issues with saving and transferring your progress across devices.
• Make sure you go to the city view before you exit the game (it won’t sync correctly if you close the game on match-3 levels, in the Friends menu, etc.)
• Exit the game correctly: Close it to your multitasking bar and then swipe it away from the multitasking bar. (Don't lock your device with the game running or don't leave your device with the game running as the device will lock and the progress you’ve just made may fail to be saved.)

To save the game correctly you need to make progress. To make progress means to improve one of the parameters below:
1 - XP points
2 - The number of the earned anchors, shovels, keys
3 - The number of the earned pieces of the Mysterious diagram, Gold Runes, Skystones
4 - The number of the completed levels in the Ship, Cave and Pyramid

Attention: Gifts, Taxes, Resources, Crystals, Portal, Lotus, Wheel and other items can't be saved and synced on their own if you do not improve any of the parameters above when you switch between devices. For example, when you collect taxes, or gifts, but do not make progress, it won't be saved and transferred across your devices.
