Gurami

is a new combinatorial puzzle. Although on first glance Gurami looks like Sudoku with triangles instead of squares, it offers a whole new riddle experience.

Prof. Dr. Hans-Friedrich Bauch has been analyzing mathematical triangle and hexagon puzzles since 1989. Dr. Klaus-Peter Rudolph develops board games since 2007. At the beginning of this book they outline construction, analogies and differences between different number-placement puzzles. The research on these shape puzzles by Hans-Friedrich Bauch inspired Klaus-Peter Rudolph to create the Gurami puzzles.

This book contains 60 brainteasers and a few introductory hints on how to take advantage of the unique triangle structure of Gurami. It's in German language and can be ordered online (German site)
