The goal is to get same side pairs of the 6 tiles,

enter image description here,

to fit into a $2\times 3$ grid, so that all touching sides match like so (excluding the red part), for example:

  • $\begingroup$ Are we allowed to rotate the tiles? Also, is 2x3 two wide or three wide? $\endgroup$

  • $\begingroup$ You can rotate, and if you can rotate, whether it's $2\times 3$ or $3\times 2$ doesn't matter. $\endgroup$

    $\begingroup$ Dang, but I gotta say: If the solution is not unique, what's the point? I feel like the puzzle suddenly has much less value since little effort is actually needed to construct such puzzles... $\endgroup$ Aug 29, 2017 at 21:25

I found this by hand. I don't know if this solution is unique.

     4   2
   1 X 5 X 5
     2   6
   6 X 3 X 1
     5   2
   1 X 1 X 3
     4   4

I'll draw a picture of it later.

  • $\begingroup$ @JanIvan Sorry I just beat you to it. It is interesting that you found the same solution as I did. Maybe it really is unique. $\endgroup$ Aug 29, 2017 at 11:10
  • $\begingroup$ Yea found second, and it is very similar honestly $\endgroup$

There are exactly

8 solutions, or if we don't count rotations, the answer is 4 solutions, or if we count $3\times 2$ table, 16 solutions.

solutions!

How did I find them?

Programming :P

Where are the solutions?

And?

And??

  • $\begingroup$ Only 4 if you don't count rotations. $\endgroup$

  • $\begingroup$ Yes but we're allowed to rotate. $\endgroup$
    – MCCCS
    Aug 29, 2017 at 14:48
  • $\begingroup$ In that case there are 16, since you can also rotate 90 degrees. $\endgroup$
