Long before Sudoku hit the scene, there were Logic Grid Puzzles. Developed by Lewis Carroll, these logic puzzles rely on deducing a complex solution from only a few pieces of information. (Who knew the author of Alice In Wonderland was also a brilliant mathematician and logician? ) Now, you're probably thinking, "Whoa, that all sounds really nerdy " And you're right. But it's also really addicting. With only a few clues, you'll be able to fill in the entire 6 grid puzzle after you put your brain to work. The puzzles in this book were originally created for the 'Logic Grid Puzzles: Word Games for Brain Training' app and have been downloaded and solved hundreds of thousands of times. But the puzzles are now available for everyone who loves solving them the old fashioned way: with pencil and paper. So grab a cup of coffee, a pencil, and a comfy chair. 210 logic grid puzzles await
