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.
