Little book of Trigons puzzles

Thanks to your support and appreciation of the two Trigons book I've published, here is a new book with new designs and patterns of the trigons
This time, the book is smaller in size, so it's easy to carry around with you. It contains 67 puzzles, most of which (53 to be accurate) are standard size, 0 to 6 . However, there are a few 0 to 5 (10 of them) and 0 to 7 puzzles (4 puzzles). And of course, to spice things up a little, some of the puzzles are the so-called "Zero Trigons", which are even more difficult to solve
One thing is for sure - for it's size, this book surely packs a punch You will be challenged
