Unlock any 20 arcade stages by collecting tokens.
As you collect tokens in one arcade machine, future stages on that machine are unlocked (by default, only the first stage is unlocked). You can scroll over to the locked stages to see how many tokens you need for them to be unlocked. Note that unlocking stages does not deduct any of your tokens.
This applies across the arcade. Unlocking 10 stages in one machine and unlocking 10 stages in another will give you the trophy.
Unlock a question block on any game grid.

Is Keep Respawn
Collect every arcade token in a single game type.
In other words, this trophy is asking you to get a total of 111 tokens from any one of the arcade machines - which, in other words, is asking you to complete EVERY challenge in one arcade machine.
The best way I found to do this was to do each of the challenges one-by-one without paying attention to the others. For example, in one of the Alter Ego stages, I would first finish the stage concentrating on getting all of the Sly masks. Then I'd replay it to get all of the Ion Bits, then I'd replay it for the other missions (such as not getting damaged, finishing with full health, etc.), and the final replay would be for the high score challenge. I believe this is the most efficient way, as you're not stressing about a ton of challenges at once. Slowly but surely, you'll knock each challenge off the list, and that 111 will be achieved in no time!
Climbing the Ladder
Beat 10 high score challenges.
See Get the Spread Gun!
Get the Spread Gun!
Beat 40 high score challenges.
So this trophy is specifically asking to complete 40 high score challenges. You don't need to complete 40 on one machine - it's not even possible. This will most likely be achieved along the way to other trophies, but if you're really looking to knock this one out, complete the first few high score challenges on each of the machines until you hit 40.
For the System Cracker high score challenges, it will be very beneficial to not lose any health - you get a bonus when taking out enemy drones with full health. Destroying all of the blue and pink gems, as well as taking out every single enemy drone, and finding every Sly mask will definitely boost your high score up there as well.
For Alter Ego's, take out as many goo enemies as possible. Destroying an entire group of them will grant a bonus score. Also, don't waste time on destroying all of the purple barriers; they don't even award any points. Collecting all of the Ion Bits and Sly masks will definitely help a ton, and whenever possible, attack the Score Bones (the blocks with a treasure chest icon) to get more bonus points.
Spark Runner's is probably more difficult to get a high score in since there's very few sources of points: time boosts, atoms, and Sly masks. All I can really say here is to collect ALL of them. Nothing more to it, really.
Beat 30 Sly mask challenges.
Similar to the previous trophy, you'll have to complete 30 challenges asking you to collect those ever-elusive Sly masks. This trophy can only be achieved by completing the challenges on more than one machine, because there aren't 30 challenges on one machine!
The Sly Masks are hiding absolutely everywhere. There isn't much to say other than to check every single part of the stage you're playing in before moving on. You may have to replay the stage a couple of times if you skipped over that one part where there was a Sly mask and you knew it. One notable place to be wary of, in System Cracker, there are sometimes paths that seem blocked by the wall but still attached to the wall. This wall can be destroyed by the purple Panzer code.
Collect a total of 100 tokens.

Unlock every question block on all three game grids.
Question blocks are unlocked by unlocking the block above it, below it, and to the left and right of it. To unlock every question block on all three game grids, you'll need the following: 52 tokens in System Cracker, 47 tokens in Alter Ego, and 55 tokens in Spark Runner. You'll definitely get this trophy while going for the others, so there's no need to worry.
Collect a total of 300 tokens.

Unlock 50 prizes in the Prize Gallery.
As you earn more and more tokens, you'll be eligible to unlock prizes at Dimitri's Prize Gallery. The tokens are not used up, and the prizes are nice little tid-bits from Sly
If you don't unlock any of the prizes in the top-middle row (which are obtained by unlocking the question blocks, see Bites and Bytes
for more information on that), you'll need a total of 260 tokens to unlock the first 50 prizes in the Gallery (the 50th is the Temporal Sprocket (right shelf, second row, farthest prize on the right)). This is on the way to the 311 tokens for the following trophy, so keep unlocking those prizes as you go!
Rock out with The Cooper Gang!
This trophy is code for "Collect a total of 311 tokens and unlock the last prize in the Prize Gallery."
311 tokens is a huge task (especially considering the highest amount of tokens possible in the game is 333). There's no easy way to say this, but you've got to do amazing in each of the arcades to accomplish this difficult task. My suggestion would be to stick with the starting stages and work your way from there, but only after you've achieved all five challenges in the stage.
Once you've hit 311, go to Dimitri's Prize Gallery and unlock that last prize on the very bottom-right: the Special Arcade Key. Now that that's open, hit circle, go right, activate the secret fourth arcade machine, and enjoy your new gold as well as the epic rock show!
