here is a list i have created from various people, so dont give me the credit. there are 19 here
Here is clearly written instructions for 15 of them, from my own experience in getting them. And the locations of two more that I haven't actually got yet. Condensed in one easy to read format for all those who don't want to rifle through all the posts.
Level 1) “Learning to Roll”: Very easy to see… after you make all the small jumps up the “steps“ there is a ledge you will need to boost jump to (near the middle of the map). From there just roll along it and boost jump (or take the wood plank) across to the egg.
Level 3) “Introduction to gems”: Go to the highest point you can roll to and there is a gem there. Right near it is a ledge you can boost jump to. There is a gyro copter there get it and move out of the spot where it was just a bit. Across from this gyro copter is a taller ledge you can get to with the gyro copter. Do these steps in order. Activate the gyro copter, move backward a bit to get the gyro copter again, then boost jump to the higher ledge. Wait for your “boost” to fill back up but while you wait, notice the very tall pillar across the way, the egg is on top of there. Once your boost is full… activate the gyro copter, boost jump, and guide it to the top of the pillar.
Level 9) “First Flight”: On the second platform down, if you are looking straight at the goal from the start, it‘s on the left side of the platform, underneath it, under the glass block wall. (if you creep over there an rotate the camera you should find the little hole it’s in. If you can’t find it gyro copter down to the lower platform and turn around and look back at the one above you, you’ll see one side (now the left since you turned around) is hollow. The easiest way I have found is to be on the platform it’s above… roll right above it as close as you can get, drop off the edge and then activate your gyro copter, you should float in easily.
Level 17) “Ramp Matrix”: Right above the goal. (The goal in this board is not the one at the top but the level below). Don’t collect the gems first as this will activate the goal. Get the super jump right near the goal, wait for your boost to fill up. Then jump, boost, and lastly activate the super jump, you’ll run right into it.
Level 20) “Upward Spiral”: Right above the goal. Don’t have it yet so clear instructions will come ASAP.
Level 21) “Mountaintop Retreat”: After the first set of steps get to the corner on the flat area. Stop you ball on the “inside” corner and rotate the camera until you can see it far below you on a brown ledge. The best way is when you are on the platform above it back your marble into the “V” and back off the ledge, immediately pushing the stick back up toward the pillar it’s resting on. About halfway down if you use your boost it will give you the little extra “push” you need to make it as you are falling.
Level 22) “Urban Jungle”: From the start, go down the right path (the left one goes up, the right one goes down) and grab the super jump power up. There are several big brown pillars on this map. Roll to an area that gets you the closest to the lowest pillar. You will need to use your jump, then super jump, then boost to reach the top of the lowest pillar. There is a gyro copter on top, get the gyro copter and jump safely back down to the blue surfaces. Next you need to get on the highest pillar off in the “corner” of the map (the one where you can see two time travels on it) and you do that by going over by it and finding the super jump, but don’t pick it up as it will replace your gyro copter. Back up and line up the super jump with the tallest pillar. Start rolling and activate the gyro copter on the ground (don’t jump yet). As soon as you roll over the super jump, use it. You’ll be flying up nice and high but you still need to use your boost to go a bit higher (if you use full boost here you will overshoot, half boost is just about perfect). I usually don’t make it all the way up, but instead kind of bounce off the pillar and that takes me high enough to land on top. On top of that pillar there is yet another gyro copter, grab that. Now line up with the highest pillar from there and back all the way up to the edge. Wait for the gyro copter power up to respawn. Activate the gyro copter and roll through the respawned gyro copter (picking up another as you are using one), jump and then immediately boost to start flying toward the pillar… this is where the second gyro copter can come in handy if you don‘t quite make it and the first one is going to run out. This one you will also “bounce” off of initially but try to land on top, where the egg is. On these types of jumps and gyro copter landings, it helps greatly to push up on the right stick (with the default control scheme) to rotate the camera above you so you can see where to land. This is one of the tougher eggs to get so far, at least for me.
Level 32) “Obstacle Course“: Make it down to the ice area but don’t go onto it. There is a ramp that leads down (on your right if your facing the goal), take that down and you will see six black trap door blocks. It’s under the middle set, the one farthest from you, just jump on it and let the trap door open and you’ll fall to it. You should see the egg floating under there before you jump if your in the right spot.
Level 33) “Fork in the Road”: It is resting underneath the lowest part of the “U” shaped channel you can “ride” in. You should see it from anywhere on the map that gives you the vantage point to look under there. Up by the 3 time travel hourglasses there is a gyro copter. Use it from anywhere on the map that is easiest for you to fly under there to get it. (every place I tried it from was just as hard, so I don’t have any recommendations for you).
Level 35) “Black Diamond”: High in the air, midway down… you have to ramp to get it. Don’t have it yet so clear instructions will come ASAP.
Level 38) “Whirl”: Go all the way up to the goal but if you turn around from the way you came you’ll see the top of the loop that brought you here. Wait until your boost is full and boost jump to the top side of that loop and roll (don’t jump) right down the center and you’ll hit it on the way down, just after you start to fall vertical.
Level 39) “Hop, Skip & a Jump”: Very easy to see, just go to the gyro copter and rotate the camera up and to the right. Just line up with it between the pillars, activate the gyro copter, don‘t roll at all, jump and then use boost and head towards it. Only minimum boost works here, if your boost meter is full you’ll easily overshoot it. Around minimum is perfect. You have to pretty much fly right through the opening to get it though, it will take a few tries.
Level 43) “Ordeal”: Just past the three things that try to push you off by moving side to side there is a gravity modifier switch. You have to go over the edge slightly to trip it, when you do there is some dark brown floor to your left. Go all the way across that and then look down. You’ll see two ledges drop down to the bottom one and then use the camera along the edges to find the egg that you must drop down to get.
Level 44) “Daedalus”: It‘s at the very top under the goal. The easiest way is to have a gyro copter ready. Get right on the edge and activate the gyro copter. SLOWLY back off the edge while pushing forward toward the egg once you fall. Right when you “slip” under the ledge you need to use your boost to jump up and grab it.
Level 48) “Scaffold”: It’s on a brown ledge right under the goal. Make sure you have boost and back off the edge right over it and when you “slip” under the ledge try to boost toward it.
Level 51) “Battlements”: Go all the way to the goal. Get inside the “tower” that the goal is in. You can boost your way on top of the block that held the two fans to get a look at the egg if you want, but unlike some methods of jumping from there, my way is much easier. The “tower” is square and if you put the way you just cam in on your left then boost jump to the low ledge in front of you. There are three blocks here that make up this ledge, the egg is under the middle one, under the lip as you fall. Fully charge your boost and get right in the middle of the middle block and “back” off, as soon as you start to fall push forward (meaning into the wall) and as soon as you “slip” past the lip, fire your boost and you’ll grab the egg. If you go to the top of the fan block you can see where the egg is, and you can even try to jump from there. Either way, it’s not too hard.
Level 54) “Will o’ Wisp”: Under the large platform the goal is on. There is a gyro copter hidden under one of the little ramps you roll around on where one passes over another. You need to take the gyro copter to the top and you’ll probably have to die once to at least see where the egg is located. (hint: aim camera up as you are falling). Once you know where it is go to the closest corner on the platform above it and activate the gyro copter and “back” off the ledge. Once you fall under the ledge (you should be pushing forward towards the egg) activate your boost and you’ll fly towards it. It may take a few tries but if you have your gyro copter at the last checkpoint, the re-tries won’t be too bad.
Ok on level 59 go all the way to where you have the super jump thingie not the first one while on the platform, but after climbing a few stories. Go to the right side of the big box there should be a super jump thing right there. get one wait for another fill you blast and double bounce and blast to the tallest pillar in front of you.
From the start on 52 look down to the bottom on the right hand side of the grip ramp with 2 gravity you should see a gyrocopter. Jump down to there. Make your way back up the grip ramp right next to it and follow the road down the other side and there should be some more gravities which will switch you to the green side. follow the right road or the road right in front of you and there should be a checkpoint and a jewel. turn left go up the grip ramp then another and one more with 2 gravity thing hit the gravity thing and you should be right back at the start. Now when you start the level you are facing the grip ramp but instead turn right and look up you should see the jewel that was at the checkpoint that means dont get the jewel.Look to the left of it you should see a grip ramp you just came up from. Use your gyro, Jump,Blast and jump on the grip to get a little higher. Follow the straight path forward from the way the grip ramp you hit. It should be on a corner edge right where that path ends. If you fall just checkpoint back and make your way back up the grip ramps.
