One time my friend made a 15 puzzle in Desmos and I solved it in 6 minutes. Other than that I have absolutely no experience with speedsliding.

At the top level, is 8 puzzle just all about finding the optimal solution, and systematic methods are irrelevant?

Edit: my question was already answered elsewhere. “Yeah, pretty much, at high level you can just see optimal / or +2 / +4 solution for most scrambles without thinking” - dph

I got a sub-5 8-puzzle single on slidysim! 4.546

Edit: sub-3 lmao

Edit 2: I might make a progression thread. I don’t wanna clutter up this thread too muvh

Solid solve!

Did you use any color coding?

There really isnt any colour coding needed. The 99 puzzle is special, the rows same the same ones digit, and the columns share the same tens digit.

It’s easier to see colours than numbers imo, #freeclock

Also sorry for the double post, but because of this I got inspired to do a solve! Very close to sub-20

I accidentally invented an N-puzzle method (this is not the “advanced 8-puzzle method” that I said I was working on a few weeks ago, I already abandoned that) while I was trying to sleep at 10 PM. Here’s an example of the method used on 8 puzzle:

1. Make the top 3 tiles say “412”
2. Put 7 directly under 4
3. Put 3 directly under 2
4. With the blank square in the bottom right, do D2 L2 U2
5. Trivial last 3 tiles

It might be better for bigger sliding puzzles tho, #freeclock

this is just redux but worse
what method do you use (redux user)

What’s redux? (We’re talking about n-puzzles right)

anyway I use LBL, #freeclock

(If 8-puzzle is the general N-puzzle)
Step 1: Solve 1 in slot 1
Step 2: Solve 3 in slot 2
Step 3: Solve 2 in slot 5 and empty space in slot 3
Step 4: Do the alg " U R' "
Step 5: Solve 7 in slot 4
Step 6: Solve 4 in slot 5 and empty space in slot 7
Step 7: Do the alg " R U' "
Step 8: This puzzle is reduced to a 3-puzzle, which can be done intuitvely

This method reduces the puzzle into smaller version, for example, .....24-Puzzle->15-Puzzle->8-Puzzle->3-Puzzle.

It’s called fringe. I just use LBL cuz it works better for my brain, but if I want to get good at bigger n-puzzles I’ll learn and get used to fringe. (My main n-puzzle event is 8-puzzle)
