The Big Book of Trigons - 300 Puzzles: Three Times the Original Collection
After the huge reception of the first Trigons book, this second volume delivers three times as many puzzles - 300 in total - in a bigger format for more comfortable solving.
Trigons are DJAPE's original puzzle invention: fill each triangle so that the digits on each side add up to the sum in the corner circle. They are not Sudoku - they require a completely different kind of numerical thinking.
What's Inside
- 300 Trigons puzzles across all difficulty levels
- 7.5 x 9.25 inch larger format for comfortable solving
- Thick, quality paper
- Solving instructions and all solutions
300 Puzzles. 3× the Original. The Triangle Challenge Grows.
By DJAPE - PhD in Computer Science, Washington Post puzzle contributor since 2006, and the creator of Trigons. A substantial and original gift for anyone who loves number puzzles and wants to try something genuinely new!
