This achievement requires that you play in-game for one hour straight. The achievement is a little glitchy in a sense that it needs to be one hour in a single level. Then head to Insane Hills Level 16, called A Little Push. Here, you can get the snowboarder stuck right at the beginning by doing nothing. Once stuck, just lkeep tapping your screen ever so often to keep it from timing out. If you are lucky you may also be able to go into your phone's Setting>Lockscreen>Screen Timeout and set it to "Never," in which case you wont have to do anything but wait. Thanks to Tricky1976 for this location!
