This is the fourth in Grabarchuk’s puzzle quizzes series. Every bit as enjoyable as its predecessors, it offers the reader 103 genuinely interesting and challenging puzzles. Whether your taste is for mixed-up shapes, similarities, word-games, number-games, sequences, matchsticks or more, there’s something for everyone here. The controls are well-explained and easy to use, and the grading system leads readers forward from simplest puzzles to the hardest. On occasion I found simple ones hard and hard ones easy, but that’s probably just because of the type of puzzle I solve most easily.
Solutions are easily accessible. Since the puzzles are all multiple choice, there’s no need for hints, and readers can quickly go through all the wrong answers to find the right one if they're stuck. Explanations are, for the most part, simply and satisfyingly given on the results page. Just once in a while I felt a little more explanation, or a simpler explanation might have been in order, but again, that’s probably just me.
In all, this is a great, fun collection, great exercise for the brain (I’m sure I’m getting better at these as I do more of them), and a satisfying way of filling time with a kindle when there isn’t time to read. My only complaint is I wish there was a more intuitive way to return to the contents page where nicely drawn icons make it easy to return to favorite puzzles with friends.
