The Book of Trigons: 200 puzzles, top quality paper, one per page, free bonus + 50 extra puzzles! (Trigons Puzzle Books)

I haven't done Trigons for a long time, back when I had a subscription to Dell Math and Logic problems. Just did a couple of this book and it seems to be pretty much what I remember. And still not very easy. One problem though. The cover of the book (and Amazon description) says + 50 extra puzzles. Well, there are 200 puzzles in the book and that's it, no extra 50 ! And a spiral binding would have been better.

Every thing the author promises,he delivers. Sturdy paper pages for lots of eraser. And though it wasn’t mentioned the puzzles are printed extra large so the numbers don’t give you eye strain. I only have one complaint. Wish the book spine was spiral. About the puzzles, I haven’t tried them yet as I’m busy with another puzzle book,but I’ve looked through them. They are not sudoku. I’m not good at sudoku and I think I will do better with trigons…. I hope…

I've loved trigons since I found my first one in Dell's Math Puzzles and Logic Problems. The trouble was, there were never more than three trigons in those books, and I couldn't even erase them to do them over again because the paper would smear and/or tear. This book has TONS of trigons, and if I ever do get to the end and want to start over, the paper is thick, smooth, and very erasable, not the newsprint-like paper in the Dell books.

Love love love these puzzles. They are tough too! First few pages, which you think would be the easiest, I was stumped for a bit. Granted I am a sleep deprived new mother so I’d like to think that had something to do with it. But the challenge aspect is great. Highly recommend and ask for new books to be made!

Great paper. Hard to complete these puzzles.
