Sudoku (soo-doh-koo) is a 9x9 logic puzzle to superheat the very core of your brain and to challenge your numeracy, spacial awareness and problem-solving abilities. Warning: the five levels of "Penguin Sudoku Challenge: Volume 2" may leave you smugly grinning, scratching your head, sighing deeply, snapping your pencil - and you may even throw your book at the wall. But you also have permission to frame your most difficult completed 9x9s. Good luck!
Every one of the 365 word searches included in this mega volume has a theme, from "Carnivores" to "Winter Storms." But watch out: some are easier than others. Go for pop culture topics old and new like "Katy Perry," "Emmy Winners," or "Comedy Films" for an easier puzzle. Want something more challenging? Take a look at the list for "G Words." Every one begins with the letter "G," so it's nearly impossible to find what you're looking for. A perfect option for word-searchers of all ages and skill levels.
These 99 number-crunching puzzles are sudoku PLUS! Just like the familiar sudoku that solvers love, the grids go from one to nine, with each number appearing only once in each row, column and box. The twist is that you need to do a little arithmetic, too - multiplying, dividing, adding and subtracting, according to the signs in the grid. Its a fresh, challenging and mathematical take on the super-popular puzzles.
What's real? What's not? Reality is strange - and seeing isn't believing. When you look at an optical illusion, your brain tries to fool your eyes and what you expect to find on the page isn't what's there. Apart from being both endlessly fascinating and awe-inspiring visually, these illusions also force viewers to go outside their comfort zones, challenge the nature of perception, and think creatively. Their minds have to work overtime to become more flexible. That's what makes these 240 puzzles, ranging from simple scintillation effects to impossible staircases and concealed creatures, so absolutely addictive. See how Santa "measures up" to his helper; the scale doesn't seem to be telling the truth! Compare two lines: one seems longer, but can't that really be true? Look at a triangular sculpture and figure out if it's "impossible." Move a picture from side to side and watch it spin. Try to "remove" a magic glass from the plate, count the number of "F"s in a line (but only read it once!), and locate the main subject in the masterpiece "Las Meninas," painted by the artist Diego Velazquez. This collection of illusions will enable you to experience the impossible and marvel at the miraculous.
Offering 188 word searches, the newest Go!Games collection is a perfect option for puzzle enthusiasts of all ages and skill levels.
