Richer than Sudoku, Hidato(r) is the perfect number puzzle to enjoy while you sharpen your mind.

"Now a new number puzzle called Hidato(r) is poised to steal Sudoku's spotlight." - Puzzle Master Scott Kim, Discover magazine.

"Beguiling number puzzles that offer a change of pace from Sudoku. . . . Amusing and engrossing." - Kirkus Reviews (on Hidato Fun 10).

"Instead of the arithmetical deduction of Sudoku, Hidato . . ., is more of a workout for spatial reasoning skills; the trick is to figure out the right path through points on the grid from among all the possible pathways." - Kirkus Reviews (on Hidato Fun 10).

Hidato is a pure logic puzzle that is easy to learn and difficult to master, making it the perfect challenge. Like Sudoku, Hidato features easy-to-follow rules combined with increasingly difficult puzzles. 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 reveal the secret!

Each volume of the Hidato fun series presents 203 brand-new Hidato(r) puzzles at five difficulty levels for hours and hours of fun and entertainment. New volumes will be available on the first of every even month (Feb., April, June, Aug., Oct. and Dec.).

Hidato is featured worldwide in magazines, newspapers, books, online, mobile and more.

Hidato helps develop logic skills. The Davidson Institute of Science Education in Israel, which is the educational arm of the world-renown Weizmann Institute of Science, recently granted Hidato puzzles to outstanding kids participating in their math and science online programs.
