In iStunt the player controls a snowboarder, helping him to get to the
finish of the level. In-between are hills, slopes, half-pipes, gabs and other
more or less dangerous obstacles the player has to navigate while scoring
additional points by making stunts. More points are earned by collecting gold
stars hanging around the levels. The player can force the snowboarder to
increase speed by holding him down with his finger, make him jump by sliding
over the screen and tilt the device to produce back and frontflips. If the
snowboarder lands on his head, falls down a hole or is killed by saw blades,
the game is over and it restarts at the last checkpoint.
The game also plays with gravity, turning it upside down when the player
drives over a yellow arrow and flipping the screen while doing so, forcing him
to turn the device 180° in order to continue.
