A spreadsheet is attached that may make solving <!post=this puzzle,642003>this puzzle<!/post> easier...

2. ## Shapes & Numbers

Can you divide this large square into four identical shapes, each composed of sixteen squares, and each containing four different numbers? To assist in solving, I've included the Excel edition <!post=here,642004>here<!/post>.

The final and correct solution is attached.

That was a bit too tricksy for me. Nice puzzle though.

Thanks. Do you have some kind of algorithm for solving such a puzzle (other than endless trial and error)?

6. ## Re: Shapes & Numbers

No tricks, no algorithms. A bit of trial & error is needed but you would begin by drawing lines between identical numerals (knowing that they belonged in different segments. Also helpful, is knowing that the resulting shapes are the same size (and of the same "shape"). Symmetry certainly enters the equation.

Yes, assuming that the shapes can be obtained from each other by rotating over 90 degrees round the center of the square (which is not a priori true) helps.
