Grind 5 Rails In 1 Trick Challenge

This really isn't that hard. On the first level (Movie Lot), go to the right side of the level from where you start. There will be 5 rails. Jump up to the rail and grind it, then jump to the next rail after that one, and so on. If you can't jump that far, then when you hit the ground do a manual.

Perfect Handplants

At the Cheats Menu, enter Justin Bailey as a code. On Career Mode, Free Skate, or Multiplayer, you will have perfect balance when you do a handplant. (to do a handplant, when you go up a quarter pipe, hold TRIANGLE.)

Backflip 180

Press L1,R1, hold Circle.

Rapid Fire Rocket Grabs

You'll need a decent jump (at least 5) to pull this off effectively. Get onto a half pipe, and jump as you would normally do. Now do a rocket air (Down + Square, in case you're not sure) four times. On higher jump levels you can do more, but four is a safe number to start. Then as you land, do a cess slide and manual trick, then jump again. do another three or four and Slide + manual. Rinse and repeat as much as you like. Rocket Grabs are executed much faster than other tricks, which means that 5 to 7 of them can be pulled off if you press square quickly (and timingly enough. Remember, you only have so much air, even at max juice). Your multiplier will skyrocket in about a minute, taking out a bit of the difficulty in timed runs. The best score I got from that kind of trick was about 2 million. (One last thing; you can always spice up the RFRG with combining other tricks, like front flips and abstract bio flips, and it can boost your score greatly than to just do nothing but rocket grabs). Skate Straight!

Get Big Points On The Boardwalk

To get a lot of points on The Boatdwalk go near the tunnel with thes skull (The one that the rollercoaster goes into) and grind the side of it when your mutiplyer gets to about 60 and jump off. Note: Make sure not to fall or just put the perfect grind code on.

High Trick Score

First you need to find something that you can grind for a while, then grind it. As you're grinding, just do combos with the grinds, all you have to do is hit triangle when you fix your balance and you switch up, and you can add some extras in like spins, grabs, cess slides, transitions, manuals and fakie. It's really not that hard, all you need is to be able to balance. My highest trick score doing this is something like 537,000 on the coping of a bowl. Just remember grabs/manuals/fakie/spins help your multiplier. Have fun.
