1. Starting Boost
Description: Change from the stopping position to accelerating position on the word "GO!"
Gamerscore Worth: 20G
How to Earn: At the beginning of every race you start in the stopped position which is just standing facing the screen.

The counter goes 3, 2, 1, GO. You need to time your launch to jump from the stopped position to the forward position right as it changes to GO. So as it is counting down, right after saying "1", quickly jump and land sideways placing your right foot forward and left foot back (or left forward and right foot back). This may take a couple of races to get the timing down but it is not too hard. You will be doing a bunch of races before you are finished the game so you will have countless opportunities to try this.

2. Item Attack
Description: Stomp your front foot when you have an item.
Gamerscore Worth: 10G
How to Earn: As you are going down the hill in the races you will occasionally see a glowing line between 2 small objects. Ride over the line to gain a random object. Once you have it the announcer we say something like "You got an item" or "What did you get?". To use it, simply pick up your front foot and then stomp it back down while on a ground surface.

3. T Glider
Description: Spread your arms wide to the left and right while in the air.
Gamerscore Worth: 10G
How to Earn: Ride or jump off a ramp and simply spread out both arms while you are in the air.

4. Landing Boost
Description: Perform an air trick and stick the landing.
Gamerscore Worth: 20G
How to Earn: Ride or jump off a ramp and perform any trick you like. Just twist your body for a simple spin. Land it by bending at the knees slightly and you will have this finished.

6. Triple Air Trick
Description: Twist your body while in the air and perform at least 3 air tricks.
Gamerscore Worth: 30G
How to Earn: This is probably easiest to do with 3 consecutive spins. Jump off a big ramp and just twist your body from side to side to spin. If you need more air time to perform the trick, the biggest ramps are in the "Fly Distance" event. You can also try spins with grabs.

7. Front Grab
Description: Raise your front leg while in the air and perform a front grab.
Gamerscore Worth: 10G
How to Earn: Ride or jump off a ramp. Now while standing sideways, just kick your front foot out to the side and hold it for a few seconds. If you need more air time to perform the trick, the biggest ramps are in the "Fly Distance" event.

8. Side Grab
Description: Raise your back leg while in the air and perform a back grab.
Gamerscore Worth: 20G
How to Earn: Ride or jump off a ramp. Now while standing sideways, just kick your back foot out to the side and hold it for a few seconds. If you need more air time to perform the trick, the biggest ramps are in the "Fly Distance" event.

9. Air Trick Sideway Combo
Description: Perform an air trick with 2 consecutive horizontal revolutions and land.
Gamerscore Worth: 40G
How to Earn: Basically just ride or jump off a ramp and do two spins. Jump off a big ramp and just twist your body from side to side to spin. If you do three you will also get "Triple Air Trick" upon landing. It has to be a clean landing too. If you need more air time to perform the trick, the biggest ramps are in the "Fly Distance" event.

10. Air Trick Vertical Combo
Description: Perform an air trick with 2 consecutive vertical revolutions and land.
Gamerscore Worth: 40G
How to Earn: Just ride or jump off a ramp and do two flips. The easiest flip is the front flip, so just jump off a ramp and lean forward to start flipping. You need to complete 2 flips and score a clean landing for this to work. If you need more air time to perform the trick, the biggest ramps are in the "Fly Distance" event.

11. Boost Max
Description: Make a clean landing with your boost at max.
Gamerscore Worth: 80G
How to Earn: Your boost meter is at the bottom of your screen and you increase your boost meter by doing tricks. The more tricks you do while in the air the more boost you gain. You need to max out your meter while airborne and then make a clean landing. To land, just slightly bend your legs at the knees before hitting the ground. It is almost automatic.

12. Riding Trials Complete
Description: Complete all the Riding Trials.
Gamerscore Worth: 30G
How to Earn: The trials are where you will start the game. Trial 1 is the Riding Trials and you will be tasked with completing the basic move set here. The board and character selection does not really matter for the trials so just pick what you like. Prior to starting the event the game will run you through each task and give you a diagram of how to do each of them. In Trial 1 you need to do the following in a single run:

1. "Face your feet sideways to go."
2. "Face your feet forward to stop."
3. "Lean forward to speed up."
4. "Tilt your body to the left and right to pass between the flags." You only need to make it through a couple of them.
5. "Raise your front foot and stomp to activate your item." First, you need to ride over one of the glowing lines to actually pick-up an item, then you can use it.

13. Fly Distance Trials Complete
Description: Complete all the Fly Distance Trials.
Gamerscore Worth: 30G
How to Earn: Trial 2 is the Flying Trial. The board and character selection does not really matter for the trial so just pick what you like. Prior to starting the event the game will run you through each task and give you a diagram of how to do each of them. In Trial 2 you need to do the following in a single run:

1. "Just jump up if you want to catch some air."
2. "Use a ramp if you want to catch some serious air."
3. "Spread your arms while in the air to glide." While standing sideways and in mid-air, hold both your arms straight out to the sides.

14. Air Trick Trials Complete
Description: Complete all the Air Trick Trials.
Gamerscore Worth: 30G
How to Earn: Trial 3 is the Air Trick Trial. The board and character selection does not really matter for the trial so just pick what you like. Prior to starting the event the game will run you through each task and give you a diagram of how to do each of them. In Trial 3 you need to do the following in a single run:

1. "Do tricks by twisting your body in the air." Just twist around a bit while airborne to do different tricks.
2. "Raise your front leg while in the air to do a front grab." While in the air and standing sideways, kick out your front foot and hold it for a second or two.

15. Jib Trick Trials Complete
Description: Complete all the Jib Trick Trials.
Gamerscore Worth: 30G
How to Earn: Trial 4 is the Jib Tricks Trial. The board and character selection does not really matter for the trial so just pick what you like. Prior to starting the event the game will run you through each task and give you a diagram of how to do each of them. In Trial 4 you need to do the following in a single run:

1. "Keep your balance while you're grinding, or you will fall." If you are having trouble, an easy way to do this is to just start the event and get out of the camera's view. You should land right on the first rail and ride it the whole way to get your check mark.

16. Free Race Master
Description: Finish a "Free Race" race with Rank A.
Gamerscore Worth: 50G
How to Earn: I recommend trying to do this with the following settings:

Race: Lv.3 - Shellfish Stairs
Character: My Avatar or Krystale
Board: Rare Board - High Top
"A" Rank reference time: 1'08"759

This is just a straight race to the bottom and the fastest time wins. Play the course a few times to get a feel for it and then get to the bottom as fast as you can by using whatever paths and shortcuts get you to the bottom the quickest. Don't forget to use your Boost start and lean forward during the entire race to go faster. Initially I was trying to get this on the Lv.1 race and could never come close. I was about 10 seconds away from the "A" rank reference time. After switching to the Lv.3 race, I got it on the third run. You can cut off huge sections of this race by just going off course and splitting the "S" curves in half with a straight line. Even though there are more racers in this event, they stay on the course and are never even close to you. Do a mini jump and spin to get boost which will help you blast past the off course sections. Then just be sure to aim your landings so you are facing the right direction when you get back on course.

17. Downhill Slalom Master
Description: Finish a "Downhill Slalom" race with Rank A.
Gamerscore Worth: 50G
How to Earn: I recommend trying to do this with the following settings:

Race: Lv. 1 - The Snowfields
Character: My Avatar or Krystale
Board: Rare Board - High Top
"A" Rank reference time: 1'10"891

You need to get down the mountain as fast as possible while navigating through the gates at the same time. For every gate you miss, you will receive a 2 second penalty. Again, just keep replaying the first race until you memorize the locations. By the time I got my first "A" rank I was able to hit 31 of the 32 gates without too much trouble. Remember to pretty much lean forward the whole time for more speed and there are a couple of turns where you will need to make a sharp slow turn to get between the gates. Other than that it is straight ahead with some slight directional adjustments.

18. Balloon Buster Master
Description: Finish a "Balloon Buster" race with Rank A.
Gamerscore Worth: 50G
How to Earn: I recommend trying to do this with the following settings:

Race: Lv.1 - Adrenalin Peak
Character: My Avatar
Board: Rare Board - High Top
"A" Rank reference score: 3000 points (Thanks Terrin)

The big trick here is to try and keep your combo going. For every balloon you get, your combo points increase and the next balloon of the same type will be worth the new point value assuming you can collect it before your combo meter runs out. For example, the first yellow balloon is 10 points, then 20, 30, 40, 50 and finally 60. Once you hit 60 each yellow balloon after that is also 60 points assuming you can keep your combo going. Once you break your combo you are reset back to 10 points per balloon. There are also red balloons and they start at 50 points.

19. Fly Distance Master
Description: Finish a "Fly Distance" race with Rank A.
Gamerscore Worth: 50G
How to Earn: I recommend trying to do this with the following settings:

Race: Lv. 1 - Triple Cascades
Character: My Avatar, Glopee or Pestor
Board: Rare Board - High Top
"A" Rank reference score: 1404 points

This is possibly the easiest "A" rank to get. All you need to do is stay in the air as long as possible. To help achieve this always hold both arms out to glide as long as possible and as soon as you land, jump again. On the Lv.1 race you have 3 large drops where you can get a ton of distance from. You can jump 3 to 4 times before the first big jump. These small gains will get you over 60 yards before the first big jump and if you keep doing the small jumps throughout the entire event they really add up. Jump and glide on the first large drop for a total around 300+ yards. Keep doing mini jumps all the way to the second large drop and you will be close to or past 600 yards. Now keep jumping to keep your score rising all the way to the third large drop. You can get a huge 300+ yards off this one jump if you nail it just right. You will be around 1200 yards at this point. Finally, keep doing the mini jumps until the finish line.

19. Trick Score Master
Description: Finish a "Trick Score" race with Rank A.
Gamerscore Worth: 50G
How to Earn: I recommend trying to do this with the following settings:

Race: Lv.1 - Adrenalin Peak
Character: My avatar
Board: Rare Board - High Top
"A" Rank reference score: 11968 points

This one is also pretty simple. As you go downhill, just keep jumping and doing quick spins for 300 to 400 points. Then as soon as you land, jump and do another spin. You don't even have to really worry about the other racers or even steering for that matter. You are just going for the most spins you can get before crossing the line. Repeat all the way down the hill and you should easily get the "A" rank.

20. No Crash Ace
Description: Finish a race in 1st place without crashing.
Gamerscore Worth: 20G
How to Earn: Again, this will get easier to achieve once you have played for awhile and unlocked better boards. I did this on the Lv.1 Downhill Slalom with Sabre and the Grim Reaper board. Just get out in front as fast as you can, be careful to navigate through the gates so you don't get a time penalty, and then don't take any unnecessary chances.

Alternately, you can also do this easily on the Lv.1 "Fly Distance" event. All you are going to do in this event is jump straight up with your arms out at a "T". It is almost impossible to crash.

21. Star Trick
Description: Get a star in a race while performing an air trick.
Gamerscore Worth: 80G
How to Earn: While you are playing the Balloon Buster event, you will notice a few star shaped balloons on the courses. These are very rare and on the Lv.1 event I have seen 2 of them. One is off a jump in the middle of the track and the other is off the middle of the big jump at the end.

What you need to do is go fast enough so that you get the distance and height to actually reach the star. To slightly complicate this a bit more, you also need to be doing a trick when you make contact with the star. I suggest doing a basic spin as these are easiest to pull off consistantly. So pick either a speed or all-around character, your best board and work your way down the hill. Try to complete a trick prior to reaching the jump that leads to the star so you will have the extra boost from a clean landing. Then lean forward to be going as fast as possible, line up and jump off the ramp toward the star. Start twisting to spin and keep your fingers crossed. This will probably take a couple of tries but you will know when you get it because the achievement unlocks before you even hit the ground.

22. I Can Fly!
Description: Get big air in a race.
Gamerscore Worth: 80G
How to Earn: You need to fly over 200 yards in a single jump. The easiest place to do this is found in Lv. 1 of "Fly Distance". You have three huge drops in a single run of the event so that equals three chances to get it. Lean forward to speed to the ramp and jump. While airborne, spread out both arms and just hang there until you land again. I got 261 yards off the 3rd big ramp in this event the first time attempting it. I used Pestor and the Overdrive board but you should be able to do it easily with anyone.

23. Jib & Switch
Description: Perform a switch riding while jibbing.
Gamerscore Worth: 40G
How to Earn: Get on a grind rail, and while riding it, quickly jump and spin to switch your feet locations from right foot forward and left foot back to left foot forward and right foot back (or vice versa). I find it easiest to do on the curved rails for some reason.

24. Only One Winner
Description: Win a multiplayer challenge.
Gamerscore Worth: 20G
How to Earn: You need another person to stand beside you for this one. Just select the first race level and get to the bottom before the other person.

25. Intense Rivalry
Description: Crash hard into another player.
Gamerscore Worth: 20G
How to Earn: You need another person for this one. When the race starts, stay in the stopping position and let the other person go down the hill a bit. Now have them enter the stopping position in a nice open straightaway. Once they are stopped you just ride downhill and guide yourself to crash straight into them.

26. One-Two Finish
Description: Finish a race in 1st and 2nd place with a friend.
Gamerscore Worth: 50G
How to Earn: You need another person for this one. First place gets easier to obtain the more you play and as you unlock better boards. As long as you can always get first, the other player just needs to be good enough to come in second. I did this with my 8 year old daughter on the Lv.1 race. We were both just using our avatars and Lv.3 "Special" boards.

27. World Debut
Description: Get your score registered in the world rankings.
Gamerscore Worth: 30G
How to Earn: Once you complete your first race and your score is uploaded to the leaderboards this will unlock. You will need to be signed into Xbox Live for this to register.

28. EZ Jump
Description: Jump while you are boarding.
Gamerscore Worth: 10G
How to Earn: Most likely this will be your first achievement. As soon as you start riding for the first time just jump straight up and this unlocks.
