Infernal Triangles
The definition of a great puzzle is simplicity - with many permutations.
John Dore has developed just that - based on combinations of 4 colours in sectored triangles. Building on the work of great recreational mathematicians of the past, Infernal Triangles presents the puzzler with a set of 24 triangles.
The challenge is to use those sets to match the shapes – and colour patterns - presented in the book. Some puzzles are simple, some are not.
For anyone who likes visual puzzles, especially mathematical ones, Infernal Triangles are fun and challenging.
