During the day, Dr. Gyora M. Benedek researches and improves the security of computer systems. By night, he invents and develops games and logic puzzles, including the worldwide hits Lights Out and iTop. He is the author of the Hidato Fun puzzle book series.

Inspired by a colorful, fascinating, swift school of fish, Dr. Benedek invented Hidato while scuba diving in the Red Sea.

The aim of  Hidato is to fill the cells with consecutive numbers from 1 to the highest number (both of which are circled) so that consecutive numbers connect. In other words, 1 must be next to 2, which must be next to 3, which must be next to 4, and so on.

Hidato Tips
Tip #1: Each puzzle has only one solution.
Tip #2: Hidato puzzles can be solved using 100 percent logic.  No guesswork is needed.
Tip #3: The first and last numbers of a puzzle are circled.
Tip #4: It is not necessary to start from the first number. Sometimes it is better to start elsewhere.
Tip #5: Working backwards (counting down in numbers) can reveal key clues to solving the puzzle.

The following example demonstrates how to solve a Hidato puzzle.

These strategies can be used to solve all levels of Hidato puzzles.

We have 1 million entries/year to our website www.hidato.com. this is with NO advertising  - NO promotion of any sort. According to our statistics (google analytics report attached at the end of this Doc.), customers loyalty to Hidato is 84.7% . Hidato books are sold throughout Europe, China and the USA and are published as daily puzzle in "New York Times", the British newspaper: "The Guardian" and Israel's largest daily newspaper "Yediot Aharonot".

The main competition to Hidato? is Sudoku. Hidato? is currently sold as hard copy booklets and books, printed in newspapers and of course can be played on-line at www.hidato.com.

The overall business of puzzles is hard to measure, but revenues in America from magazines, syndicated newspaper sales, books, and online and phone services are more than $200M annually. The New York Times earns millions of dollars a year from its crosswords and hundreds of thousands from a special phone service that provides hints. Over 30,000 people pay $35 a year for the newspaper's e-mail version. The Japanese buy more than 600,000 sudoku magazines per month. Four (4) million puzzles solved during one week on websudoku.com.

Our intention is to create a Hidato? fever worldwide, convert Sudoku players to play Hidato? and position Hidato? as the mainstream puzzle. Keeping in mind estimated global annual turnover of approx. 1 billion USD, any % market share is a solid business case.

Please note that "Sudoku" is not protected by patent nor copyrights and is not a trade mark whereby our "Hidato" is proprietary and patented! This makes a very solid exclusive business case.

In 2016, with the support and blessing of Israeli government, ministry of trade and commerce and the Israeli consulate in Shanghai, both Companies, Doo-bee toys and Games (www.hidato.com)  and AnHui Science and Tech Pub.
