Drag your finger (or mouse) left and right to steer. That is the entire control scheme. The game handles your speed, you handle the carving.
Ski between the paired gates to score points and grow your combo. Missing a gate resets the combo. Hitting a tree, rock, or pylon ends the run. Tap once to instantly go again.
Stay ahead of the yeti. If he catches you, you get knocked off the trail into slow deep snow and lose your combo.
Grab snowmen for currency, knock out missions for bonus snowmen, and unlock skins in the shop. The real objective is simple: ski past the flag from your last best run and plant it a little further down the mountain.
