 As the player races down the hillside, they can successfully complete tricks to earn points as well as to build up an ever-depleting boost meter.When the boost meter is full, the player is then able to execute special "Ubertricks", which require the player to draw a specific shape in the air, such as a heart or a treble clef.While the player knows some Ubertricks at the start of the game, additional ones can be discovered in career mode by collecting icons for that Ubertrick hidden across the various courses.
