The big book of Trigons: 300 puzzles (Paperback) (ISBN-13: 9781535086660)

This is a NEW BOOK with 300 NEW TRIGONS PUZZLES!
Welcome to my second book with Trigons puzzles! First one, simply called "Trigons book" has received such a great reception that I had no choice but to publish a new one, this time with 3 times as many puzzles as in the first one.
Trigons are NOT SUDOKU. Your goal is to fill in each triangle so that the digits on the sides of the triangle add up to the sum given in the center of the triangle.

Possible sum combinations are listed below each grid.

Solving these puzzles will certainly sharpen your mind, but before that, make sure to sharpen your pencils!

Are you ready?
