A challenge to all Sudoku enthusiasts: Have you ever thought of sliding out a Sudoku?

There is a new game combined from the principles of the popular Sudoku puzzle and the simple, yet deceiving, 15 puzzle of the 1880s. As such, the game is called Sudo15 (for the 4 by 4 size) but in general is called SudoSlide.

SudoSlide was invented by Kung-Ming Tiong, a lecturer at Universiti Malaysia Sabah, and its dynamics were analyzed together with a student, Yen-Peng Lee.

The idea for SudoSlide began around April 2006 and its analysis was completed in October 2006. The publication of the academic article on SudoSlide, which describes its game characteristics and some methods of play appeared in March, 2008 in the Game Journal http://www.gamejournal.org/game_journal_index_2008.php.

SudoSlide was also briefly introduced at a Science Carnival held at the School of Science and Technology, Universiti Malaysia Sabah in March 2008. And recently, one of the authors (Kung-Ming Tiong) talked to Mr. Balasingam of sudoku.com.my and was invited to write this short description on SudoSlide. » Read more
