A better sliding 15 puzzle solver

[AWildMimikyuu]

The previous forum post also links to a solver, but I've found a method that's faster and easier to follow

 

1. Open this page
2. Upload a 4x4 number grid image (the one in the trophy guide will work)
3. Increase the row/column counts to 4
4. Click "Crop Image"
5. Press the right arrow in the middle of the page to set the goal arrangement
6. Click the bottom-right tile on the Start grid to set it as the blank space
7. Click "Tile Selection Mode" in the bottom right
8. Open Welcome Park, select the puzzle minigame, line up the camera with the grid and take a photo
9. Start the puzzle on the 15-piece option
10. Once it finishes shuffling, memorise the bottom row (it'll be obscured by the "Continue" button) then press the PlayStation button to pause it
11. Drag the tiles on the grid to match the shuffled puzzle
12. If you have a red banner stating that the puzzle is unsolvable, unpause Welcome Park and shift 1-2 entire rows (towards the direction indicated by the wavy lines), then swap the tiles on the solver to match
13. Click "Solve" at the bottom of the page
14. The puzzle will solve itself and log all moves made into a new "Solution" box at the bottom
15. Memorise moves 1-4, then unpause Welcome Park and complete those moves (you'll need to flip the directions - e.g. "left" means that the piece on the left moves into the empty space to the right)
16. Use the PlayStation button to repause Welcome Park then repeat the last step for the next moves

 

I got the trophy on the second try with this method (30 seconds)

 

OPTIONAL: if you're using the solver on a PC, you can make the solution box bigger using Inspect Element

1. Right click the grey bar at the top of the "Solution" box
2. Click Inspect Element
3. Find the line that starts with '<div class="card-body"'
4. Right click it, then click "Edit as HTML"
5. Find the section 'style="max-height: 15vh;' and increase the number 15 (I chose 300)
6. Click outside of the text box th confirm your changes, then the X in the top right to close the inspect tools

This thing goes so fast how do you even follow that ? And the tiles are not shown in the solution, just step numbers.

 

Edit : Nervermind I'm just an idiot, its always the blank space that moves.

 

Got it now, thanks, my small brain would never finish that on its own.

Thank you! It worked for me! 

 

Also, I took a slow-mo video of the program solving the puzzle so I could follow along by video. I kept confusing myself when just reading it.

 

Again, thanks!! Definitely earned the upvote.

This was really helpful, thank you! Slide puzzles are the bane of my existence lol.

At first your steps seemed like nonsense but it was just getting down with the basics of the website made. Big thanks to whoever coded it, as it does a better job than other puzzle solving alternatives out there. And of course, thanks to you for sharing such valid information with us. I had to do some tweaking to the main image to get the other puzzle trophies but it's all about getting the best RNG combination with these puzzles. Making sure that the small numbers are mostly on top and big ones on the bottom, that way you have a lot of time to solve them. Welcome Park is probably one of the worst in-game console tutorials one could sit through. No wonder why the Vita died, all these useless features were never asked for in the first place.

The slow-mo video did the trick for me. Thx. Now i just need a solution for the 14 piece puzzle. My brain is unable to figure it out myself. Anyone got some tricks or tips? 

 

EDIT: Nevermind, just got it after 2 more trys

Thank you stranger,
You saved me from a 6 hours grind

Thanks for the picture, it was impossible to do it this way, but the picture worked for me. After struggling for half an hour, I was able to solve it with my own efforts.

 

I started the game with this first, I wouldn't continue if I didn't get the trophy. That's why this is the first trophy unlocked   Now I can finish it quickly
