****not my solution, pulled it from a PS4 guide to help on here**** This Achievement requires you to land each trick at least once, but there is more to that than you would think. While the grinds are very straight forward, you will need to complete each of the other tricks in all of the four difference stances. Please see below for an explanation of each.

Standard
As it sounds, this just means completing the trick normally. You will probably end up doing this naturally while playing through the three difficulties.

Switch
The switch stance is triggered by landing a 180 spin using either or . Once you do this, all tricks you complete until you perform another 180 spin will display with "Switch" before the name. The best way to work on getting these it to just immediately land an ollie with a 180 degree spin when you start a level, and then do not do any more spins for the rest of the level.

Nollie
A trick in nollie stance is performed by holding down both and briefly before executing your trick. This takes some experimenting, but practicing will help get a hold on it. This does work for tricks that require you to have a specific trigger held down as well. So for a Nollie Frontside Spin, you would need to hold down and to start, then right before you want to execute the trick you would just hold down and press . If done correctly, you will see "Nollie" at the beginning of the name.

Fakie
The fakie stance is the most complicated to pull off. After getting into the switch stance, you will need to hold down and briefly before doing a trick for it to count as fakie. So, to start, you want to trigger a 180 spin, and then you would hold down and before your trick just as you did with the nollie. If done correctly, you will see "Fakie" at the beginning of the trick name.
As stated in the road map, it is best to save this trophy for last since you will have performed many tricks up until that point. You can go to any level such as 1-1, and just complete each trick until you get this achievement. You need to actually land the combo that you performed the trick in, or you will not get credit. It is important that you don't restart the level until you either get to the crowd or bail, as progress sometimes does not save until the level is flagged as finished.

It's better to start with the fakie tricks and work your way backwards through nollie, switch, and then standard as you are least likely to have fakie and nollie tricks completed.

Actually the tricks on stance mode are not hard at all to perform. You DON'T need to hold RB and LB before executing a move in order to perform a "nollie" or "fakie" maneuver.

To enter the "switch" stance simply turn the skateboarder 180 degrees while in mid-air by pressing RB or LB. He'll have his back turned to you on this stance. ( If done correctly the name "switch" will appear before the name of the trick, for instance: "switch" kickflip).

To enter the "nollie" stance simply PRESS RB and LB simultaneously once while on standard position, then execute the trick as you normally would in standard position. ( If done correctly the name "nollie" will appear before the name of the trick, for instance: "nollie" kickflip).

To enter the "fakie" stance simply PRESS RB and LB simultaneously once while on "switch" position, then execute the trick as you normally would in standard position. ( If done correctly the name "fakie" will appear before the name of the trick, for instance: "fakie" kickflip).

If you hold the buttons you'll execute a stance trick just fine but it will be harder to manipulate the left stick and pull off the stunts while holding these buttons. I did 99% of the tricks holding the buttons before I found out you can simply press them instead of holding and I must say my life got much easier and I managed to pull off every trick faster as well using this method.

Regarding knowing if the trick counted for the achievement, as long as you don't get a sloppy or sketchy landing the trick will be valid, you don't necessarily need to finish the level by reaching the crowd or face planting yourself on the ground. The achievement unlocked for me immediately after pulling off the last remaining stunt, I think I didn't even land on the last trick and it popped. I do recommend you get a perfect landing after every trick though, just to be sure.

Remember, you must pull off every stunt in the "trickcionary" at least once on the standard position and on the 3 stances as well: "switch" "nollie" and "fakie". I'm not sure if the grinds are also required for this achievement but they are pretty straight forward and unlike the tricks they don't have a stance mode, you'll probably end up executing all of them more than once just by playing normally trying to complete the objectives for each level and getting massive combos.

Well, I believe I covered up everything about this achievement. If something is still not clear enough and you need further info please PM me and I'll gladly reply asap.

Good luck to everybody who might try to complete this game and happy hunting!
