Here is a challenge that puzzle fans will find simply irresistible: a really smart, varied, and original collection of more than 200 contemporary brainteasers. Some are visual, others geometric, and still more are topological. They play games with words and numbers, and with matchsticks and coins. And many of them are of World Puzzle Championship level; in other words, really hard. Divide figures into their congruent parts, or rearrange the pieces of a patterned star so that the result precisely matches a checkered cross. Try a little puzzling origami: fold an origami square exactly six times to create the shape of a house. Do cubical inversions, shift coins around from shape to shape in a given number of moves, and much more.

Strimko is a logic number puzzle invented by The Grabarchuk Family in 2008. It is based on the idea of Latin squares described by a Swiss mathematician and physicist Leonhard Euler (1707-1783) in the 18th century. All Strimko puzzles are solvable with a pure logic, no special knowledge is required. Strimko uses only three basic elements: rows, columns, and streams. All elements have equal numbers of cells, and the goal is to make each row, column, and stream containing the whole set of specified numbers. Cells in the grid are organized into several streams of equal length, which often run diagonally and even branching. Such mechanics creates entangled patterns resulting in interesting challenges and unusual logic. This book contains a specially designed collection of 150 easy-to-master puzzles with 4 x 4 through 7 x 7 grid sizes. Puzzles are arranged from the easiest to the hardest ones so that you’ll progress in solving skills with each next puzzle. Strimko challenges were handcrafted by Helen, Tanya, Serhiy, and Peter Grabarchuk, and up to date hundreds of original Strimko puzzles were published in various forms and platforms.

Strimko 7x7: 150 Master Number Logic Puzzles

This book is Volume 1 of a wide puzzle-book-web project entitled Age of Puzzles. The entire project is intended to present the most original and interesting puzzles created by myself and many other puzzle folks, and to do this with a close connection to all historical achievements in the Puzzle World. Another, but no less important intention is to show to the readers all presented puzzles in such a way that they will be inspired to make and solve these puzzles. For this, many puzzles are supplied with large-sized drawings ready to be photocopied in color, black-and-white, or gray scale, and then to be cut out. Also, numerous clear diagrams allow the easy making of the chosen puzzles, with use of just some simple materials at hand.
