104 Puzzle Quizzes HD is a book of visual (geometric, spatial, logic) puzzles. All the designs are original, and all the designs can be answered within your Kindle or other reader device. The answer is multiple-choice. A wrong answer invites you to continue trying, a right answer explains the answer.The puzzles range in difficulty from easy and fun for the kids to try all the way up to fiendishly difficult. For instance, in the super easy category, New Triangle Frame invites us to insert the right shape into a blank space. Something my grade-schooler can do, as I've asked her to give it a try. But on the other end of the difficulty scales, Triangles in Coins asks us to count how many isosceles triangles can be formed by joining the center points of circles (coins) in an image that consists of 13 circles. Sounds easy enough.I love these puzzles and have downloaded all of the Grabarchuk puzzle books. Once you work them, you can't work them again (you know the answers), so I'm thankful the Grabarchuks keep on producing more, and at a cost of just pennies per hours of entertainment.
