There are two ways of saving your game in MMX Hill Dash, you can either save it straight to your device using 'Local Save' or using your Facebook login details using 'Cloud Save'. To Cloud Save via Facebook you need to connect to Facebook in game which can be done via the Results screen after any race.

Only the Cloud Save option is capable of letting you transfer your game across multiple devices and platforms, so please think carefully about how you choose to save your game.
