Hint: Handgrind:
Press Down(3), Triangle during game play.

Hint: Boardwalk: Hidden grind:
When on the roller coaster track, press Up(3), Grind to do a "double grind". You need to be near the tracks, since you are grinding both tracks at the same time.

Hint: Boardwalk: Easy points:
After you have unlocked the secret area, you can go to a tall spiral lighthouse. Go inside this lighthouse. The bottom is hollowed out. Get some speed up from the halfpipes outside the entrance then go into the lighthouse and hit one of the walls at an angle. Start wallriding up the middle, continually jumping and wall riding again around the inside walls. When you get about half-way up the inside, slow down your jumping so that instead of climbing up you are just wall riding around in an endless loop. You can get your multiplier up to 199X and do a trick worth 30 million points. This is also good for getting up your Wallri, Fakie, and Speed stats. Go to the roller coaster and jump on the track. Grind either the two middle rails or the rail on the far right. Jump up and down continuously until you decide to jump off. This allows you to complete some objectives on that level and also get a massive amount of points in case you run out of juice. At the area boardwalk with the shark ride, you can grind the outside lights for a near infinite time, jumping every time you reach one of the straight segments. It is possible to get over 1.5 million points.

Hint: Flatland: The curious lookround:
While blading on Flatland, make sure you are not pressing X then press L1 + R1. Your character will peer over their shoulder and turn, however it is not however a Cess Slide.

Hint: Movie Lot: Grind the third traffic light
One of the challenges is to grind two traffic lights. After you do this, a new challenge "Grind the third traffic light" will become available. In order to do this, vault over the bike rack and onto the traffic light. From there you should be able to jump to the third traffic light.

Hint: Movie Lot: Secret bowl:
There is a secret bowl in the scientist lab. To get in the secret bowl, grind the top of the test tube towards the joint on the top. When you get close to it do not jump off, just continue grinding until you hit it and crash. When you crash you will end up inside the test tube in a bowl. You cannot get a big combo inside the bowl, but can do a tweaked look back judo with only a small amount of air.

Hint: Museum: Ark Of The Covenant:
The Ark of the Covenant can be found in the back area. Go up top the set of three quarter pipes hanging from the ceiling. Handplant the Ark to get a better view.

Hint: Museum: Hidden grind:
When on the display cases that are somewhat pyramidal, press Up(3), Grind to do a "double grind".

Hint: Extra points:
To rack up a huge rotation combo, go into a wide bowl or any place where you can do a continuous grind without jumping to a different track. Grind, then jump. Hold either L1 or R1 to do a rotation, then land back into the grind. Keep doing this in the same direction (L1 or R1). This will make it possible to get very high rotations accumulated. Just watch your grind meter -- it goes haywire with more tricks. To do a near-infinite handstand combo, go up to a quarter or halfpipe in any level. Do a normal handstand, rocket, abstract, etc. Hold Down to make the meter go down, causing your handplant to end, but the trick is to keep pressing Grind repeatedly. As you get better, you can do up to a 50 trick combo. Note: This does not always work. You can do the following trick fresh. You do not need to use a cheat, and you can do it with all your stat levels at zero. Find a rail. Straight, level, and long ones work the best, such as the long benches between the purple octopus and the water in the Boardwalk level. Stand still at a 45 degree angle from the bench and press Triangle. You will start grinding very slowly. You may have to jump if you try it elsewhere. While grinding, rapidly press Triangle and press Left and Right (D-pad recommended)to keep your balance. As long as you keep pressing Triangle and keep yourself balanced, the game will count lots of grinds; each increases your multiplier. You will be making a lot of tiny adjustments to keep your balance, so the multiplier will increase quickly. It is important that you go as slow as possible, so that you do not run out of grinding surface. When you feel that you have gotten enough points, press X to jump off and land the trick. With practice, you can get well, well over 1 million points. Go up any quarterpipe and do any desired tricks. Do the Cess Slide after your wheels hit the ground and try not to combo it with your tricks. Find a half-pipe or a bowl and do some tricks. Before you land, do a Cess Slide into a Manual. The trick keeps going, and if you have enough skills, you can do it as long as desired.

Hint: Flying Handplant:
When going off a ramp, hold X. Once you approach the top, do a handplant and at the same time release X.

Hint: Hand Grind:
Jump, press Down(3), and grind.
