Like any endless runner or similar casual arcade games, you cannot expect to instantly break records on your first set of runs in Subway Surfers. Despite having simplistic controls and game mechanics, Subway Surfers is a type of game that is easy to learn, yet hard to master. There are plenty of nifty tips and trick to know, but spending time to actually engaging in practice runs will always yield better performance.
Even if you have spent time on other endless runner games, it is best to get a full grasp of the control sensitivity of your device relative to Subway Surfers. This is especially important especially considering that the pace of run continues to accelerate the farther you travel. You may opt for the conventional single finger hold on your device, although using 2 fingers can greatly improve reaction times. In any case, trying both methods to discover which one works for you better is recommended.

The initial tutorial will only run you through the basic swipes, from switching lanes by swiping left or right as well as swiping down to slide under barricades and swiping up to jump over other obstacles. There are, however, some simple tricks that you need to learn and it is not just for a much better performance, but sometimes to save yourself from disaster as well.
To start off, you can switch lanes in midair. Your sense of physics and logic might tell you that you are confined to your lane whenever you jump. In Subway Surfers, however, being able to swipe left or right during a jump is perfectly normal and should be utilized fully even in your starting runs. In the same manner, you can also swipe down any time within the jump to quickly fall back down on the ground or platform. There are instances when you have to time your jump perfectly just to nab all the coins in-between trains and if you jumped a bit off the mark, swiping down at the right time can earn you more coins. This can also be helpful in some situations where obstacles come one after another and you have to make a quick jump or landing to be able to slide through a barricade.
