Fifteen puzzle

[KrazyFK]

István has done it BLD.

I'm jealous. Someday I'll have to do it too.

I've done this BLD too, using an absolutely awful 3-cycle method (although I started with an 8-puzzle before working my way up). I'm sure you'll come up with a better way of doing it than I did when you try it.

I've done it BLD too, took about 6min iirc. I used a 2-cycle method

Well, I never thought of doing it blindfolded
I guess I'll have to buy/make one, it would not be possible on a computer.
I'd like to see someone solve a 5x5 or bigger square blindfolded.

How do you guys go so quickly? What method do you use?

At the end I solve the third "layer" and hope the last three are in place. If they aren't I have to use this awful three-cycle I made up. Does anyone do anything different?

I'll make a tutorial on my method later.

Hah, how do make an alg for the 15 puzzle??

I kind of put the 13/14/15 tiles in a square on their own in the bottom left by scrunching up 9/10/11/12, switch them around however I want, then un-scrunch the entire thing.

It takes a long time, but it is a set sequence.

After first two rows, I put 9 and 13 in, then there is just a 3x2 block in the corner. Then I put 10 and 14 in, and thanks to parity, the rest will be solved.

I first solved a 4x6 version at age 11. I learned how to place the 9-15 tiles of a fifteen puzzle by poking around with it. I can solve a fifteen puzzle in under 60 seconds.

I haven't played with one of these since i was a kid. I loved that thing, no idea how long it took me. I want one now. I want a bigger one though.
