One Tɍough – Ditch

Ditch was designed by Alexander Magyarics and entered in the Nob Yoshigahara puzzle design competition at the 41st International Puzzle Party (IPP).  Although it did not win a prize, it looked like an interesting concept worthy of spending time on.  And spend time on it I did!

Ditch consists of 12 bi-color pentomino pieces where each piece is comprised of a tetromino of one color and a monomino of a different color.  The goal is to make a 4x4 square outline with the 12 monominoes.  The problem is that all those tetromino bits get in the way of accomplishing this.

The first Aha comes early on to get you started followed by a long period of learning how the pieces can interact with each other.  Some off these relationships will help form the solution while others will lead you astray.  There were some relationships that I was unwilling to ditch that kept me from finding the solution for quite a while.  I found myself reluctant to divorce myself from these poisonous relationships and I found myself in rut with Ditch.

I eventually gained the willpower to break off some of those relationships, giving me the freedom to engage in some new, healthier relationships.  With something old and something new, I successfully managed to extract the solution from the Ditch.

There were many times where I had one piece leftover that would not fit in the available space. The natural reaction is to start moving pieces around to see if you can change the space to something more receptive.  I can certainly attest to that.  However, if you end up with the same troublesome pieces multiple times, it's worth taking some time to find them a good match and treat them as a couple.

Much nicer versions of Ditch in a selection of exotic woods are available at Wood Wonders if you would like to acquire your own copy.
