Olympic Trick track:-  When on the Olympic Trick track, begin with the jump directly ahead. You have to turbo to make the jump. Press Left or Right and L1, R1 while jumping to do a roll. This should result in extra points added to the coins collected on the jump. When performing a rail slide, go a little slow and on an angle when you reach the rail jump so you slide down. Extra points are gained with the coins on the rail.

Fly:-  Use Capt. Billiard on any level. Repeatedly press Circle. The more you press Circle, the higher you will go. Note: To move forward, you will have to use boost.

Stunt mode points:-  When in the first level of stunt mode, note the very big holes. There is one hole that is by itself and is not  connected to the others. Enter that one and find the tunnel at the bottom. Enter it and collect the yellow 100,000 point coin at the end of the tunnel. 

Grapple stunt points:-  There are three yellow 100,000 point coins that can be collected in grapple stunt mode. To get them, go up the spiral object and when you jump off, use the grapple to launch up on top of that big object directly ahead of you. Once on it, use your turbo to boost yourself up. There is a grapple when you get on the straight up and down section. Go up on top of it and fall down the hole at that location. The middle of the hole contains three 100,000 point coins. 

Secret chamber:-  There is a jump directly ahead as the game begins. Use some turbo in order to make the jump. After the jump, go  to your right. There should be a hole where you can do tricks. There is an opening in the hole. You can go around the top if you use a turbo. After that, slow down at the end to find the coin. Note: It is very hard to get.
