Prepare for Futoshiki Puzzle Fever


Last Saturday there was an article in an English newspaper called The Guardian.

It is about a new Japanese puzzle called Futoshiki which can be linked to Sudoku Puzzles. I looked at their website but could not find any puzzle called Futoshiki, so probably it will only be in the paper version of The Gardian.

Feel free to e-mail a Futoshiki puzzle or related information to Passion for Puzzles, at this moment I cannot find information about futoshiki puzzles via search engines, flickr etc..

For those how are interested please read the complete article.

Sudoku Saver


Designers at GRID – part of the Innuendo Design team – have launched a new concept in Sudoku Books. Called the Sudoku Saver, the new book offers a range of options for saving, restarting or reusing Sudoku puzzles.

The concept couldn’t be simpler, a book of grids, predominately empty ones, that enable the Sudoku addict to either save a puzzle to solve later, from a newspaper, off the internet, or wherever. The saved grids can be completed at any time, and there is the option of copying one from a newspaper that you are doing today, and then do it [Read More...]


Suberi-Sudo for Mac


Suberi Sudo is a combination between a sliding puzzle, like 15 puzzle, and Sudoku.

Battleship Sudoku


Via Puzzle weblog Puzzlinks I found a few days ago a very nice variation of Sudoku, called Battleship Sudoku.

The first (and less preferred by the author) is to put a “minifleet” in a Sudoku grid and fill the empty spaces with numbers according to Sudoku rules.

The second method puts numbers on the fleet of ships so that a correct arrangement of ships will provide clues to solve the Sudoku.

The author prefers the last one. I really like them as already mentioned in a comment; Battleship Sudoku could be as famous as Sudoku. [Read More...]
