Multipliers are essential in getting high scores in Subway Surfers. They can be increased permanently by completing a set of 3 Missions. The higher your multiplier, the easier it is to get highscores. For example, it is easier to get a certain score with a 10x multiplier than a 5x multiplier.

Snap is adding a multiplayer version of Subway Surfers to the Games platform it launched back in April. The company created Snap Games to give you a quick way to play with friends from within the chat window -- all you need to do is tap on the "rocket" icon on the chat bar to launch it.
