In this third Hidato collection we offer challenging puzzles in five difficulty levels with practice and bonus puzzles included. Hidato® is a pure logic puzzle that is easy to learn and difficult to master, making it the perfect challenge. Each Hidato puzzle starts with a grid partially filled with numbers. The goal is to fill the grid with consecutive numbers that connect horizontally, vertically, or diagonally.  Hidato can be solved using 100 percent logic and requires no math or guesswork.  You need only careful thought and determination to solve Hidato® puzzles. Hidato 3 presents 200 brand-new Hidato puzzles for hours of summer puzzling.
