One of the headline-grabbing new features in Temple Run 2 is the ability to enjoy a roller-coaster-like mine cart ride. The play is essentially the same as when you are on foot, as you still have to avoide the obstacles strewn across the path ahead by jumping and ducking. However, you also have to steer the cart along the track. If a bend approaches, you need to lean with your device to tilt the cart around it, otherwise it will derail.
TIP: In these sections be sure not to tilt your device entirely to the left or right. You want to be making slight tilts to merely guide the cart round the corner, rather than any aggressive or sudden changes in direction.
When the track splits into multiple routes, you will have to make a decision over which direction to go, left, or right. Be sure, when exploring the mines, to check these routes before you take them. The wrong turn will lead you quite literally into a dead end.
