"Twisty flip":
Choose any one that can do a front/backflip. Then do it and hold left/right for a "twisty" flip.

Glitches:
Get out of Roswell:
Enable the "Slow motion", "Perfect balance", and "Different restart points" codes. Go through the blue restricted access tunnel with the alien in it, then immediately grind the rail after the exit. Jump over the gap, then grind the next rail. Then, jump onto the next rail and jump up and keep grinding until you get to the end of the rail. After you are done grinding, if you stay to the far left instead of heading up the ramp, you should be able to go through the wall and escape Roswell. After you get out, skate towards the helicopter, and you should fall underneath the level. You will not be able to move, but can jump and do tricks. You then have to restart the level. Start the Roswell level enable the "Slow motion" and "10x multiplier" codes. Just after starting, do a Fastplant and Impossible to get your special all the way up. Keep going forward and do a trick off the quarter pipe. Wait until you are about to fly off the part you started at, then just before then, do a Nollie and any special. Press Left or Right to spin your special the entire time that it lasts. You should go through the ground and leave Roswell. Restart and try again if it does not work the first time. If the spotlight hits you, you will fall under ground and can do simple tricks, but the game will have to be restarted.

Invisible boarders:
Begin game play on the School level and get big air on the bowl with the diving board by it. Get a lot of speed so you go over the sign. The camera will zoom into the bowl, and your boarder will be there but he/she will be invisible. They will remain this way until you fall.

Pass through glass:
On the San Francisco level, when you go straight ahead from the start and go down the levels parallel to Lombard Street, slow down and keep to the far right before you fall into that glass on the last level. If you are far enough to the right, you will go through the glass without breaking it.

Light particle:
Enable the "Slow motion" and "Random restart locations" codes. Go to the metal half pipe and do any trick in the middle of the pipe. Come down and go straight into the bowl. The tunnel that can be entered should be black and will not change color when you hit. Keep jumping until you are inside. Once you enter, it should spit you out as a particle of light. You cannot move around but you can jump and do tricks.
