A colorful square, dissected into four parts, with hinges marked in black. If you leave the blue piece fixed and swing the others around their hinges, a new shape will emerge. Can you guess just by looking what it will be? This is just one of the tricky geometrical gems that will make a puzzler’s mind work overtime. Try drawing a set of variously shaped polygons using only a compass and a ruler (no measuring allowed!), figuring out which of two sculptures is bigger (logic alone won’t give you the answer), and lots more.

Download Loopy Logic Problems and Other Puzzles Book in PDF, ePub and Kindle
Calculate velocity; explain the Maltese cross mechanism that's the basis of the motion picture projector; and work out the ways different pendulums (including Foucault's famous version) swing. Every attractive page in master Ivan Moscovich's eleventh collection of brain-busters offers a tricky puzzle pleasure. Sixteen tiles show either a crowned frog or a crown prince: distribute them randomly on a game board, face down, and then see if you can come up with a configuration that will allow you to flip them so that all frogs or all princes will turn up. Discern the logic of a number pattern in a partially filled-out grid and discover the missing numerals. From gnomic expansions to infinity and limit, these dilemmas demand a smart solver.

Problem solving is a pleasure - when you can get rid of those mental blocks. That's just what this collection of puzzles helps you do, even as it offers hours of entertainment. There's advice on working through the tough spots and exercising those creative mental muscles. Start with a classic about The Man with No Eyes. He's gone to the woods to view the skies. He sees a tree with apples on it: he takes none off, yet leaves none on. How can this be? Or try the numerical St. Ives Riddle, from a rhyme first published in 1202. Decipher mystery signs, make symmetry folds, and do the Twenty-Five Point Connect.

Puzzlers will feel fit to be tied - Dog Tied: If Fido is tied to a 10-foot-long rope, and his bone is 15 feet away, how is it possible that he can reach and enjoy his bone without breaking or stretching the rope? (And yes - the rope IS tied to something.) There's fun in finding the answer to this and other cool number-based problems. Dust off your mathematics and get solving. The intriguing enigmas include questions on interstellar communications, ancient geometry (Pythagoras and Plato), and even traffic patterns in gridlock city. Or play the grasshopper jumping game. It's all fascinating.

Download Piano-hinged Dissections Book in PDF, ePub and Kindle
A dissection involves cutting a polygon into pieces in such a way that those pieces form another polygon; for a hinged dissection, the pieces must be attached by hinges. A piano hinge is "a long narrow hinge with a pin running the entire length of its joint." So, unlike regular hinged dissections, which swing or twist (around single point of hinge), piano-hinged dissections fold along an edge. This book discusses the history, methods, and variations of these dissections and is rich with illustrations that clearly depict the cuts of the dissections and three-dimensional simulations of the dissections in the process of being folded. A CD that includes video recordings of select dissections being transformed accompanies the book.

Download Cunning Combination Problems & Other Puzzles Book in PDF, ePub and Kindle
There's magic in these brainteasers. Most of them play variations on the magic square, among the oldest puzzles that exist. These cubes or other shapes are made up of groups of cells, each cell containing one of a set of numbers. The set generally corresponds with the number of cells, so, for example, a five-by-five magic square would contain numbers from 1 to 25. The trick: the sum of the numbers in any one row or column (and sometimes diagonal) must be the same. It's pure mathematical beauty. Examine and attempt to figure out the workings of a "diabolic" version created by D�rer, an early variation by Lo-Shu, and variants that use colors, different shapes, and hinged tiles.
