Ditch one was one of several of Alexanders Magyarics' IPP Design Competition entries in 2024. I found this one to be quite challenging and was not able to solve it, I had to look at the solution in the interest of efficiency! You must arrange the pieces to form a 4x4 square with the single tile pieces. An instruction sheet is included showing the objective. Good luck with this one.
The pieces have a nice soft felt pad on the bottom for a nice feel when sliding them around on a table.
