There's been a changing of the guard at Hudson Entertainment, the North American flavor of Konami-owned Hudson Soft, as president and CEO John Greiner will take his leave of the company on May 15. Hudson notes that it currently has no plans to look for new blood to bring in to replace Greiner, instead stating that the U.S. division's senior exec and chairman Seiichi Ishigaki will step in to fill his shoes.

Citing the reason for his departure, the 20-year exec noted plans to "spend time with his family and pursue personal interests," which knowing Hudson as we do probably means hemming them into a corner with a bomb before admiring the carnage from a safe distance. Once the smoke clears, we wish Greiner the very best.

When asked by the BBC what the next big Sudoku-like craze will be, puzzle guru Maki Kaji (whose business card reads "Father of Sudoku") points to Slitherlink. The grid-based logic puzzle has all the ingredients of another hit -- easy to learn, straightforward gameplay, and simple rules. Even though it doesn't have the broad appeal of Sudoku, Kaji says it could easily earn the title "son of Sudoku".

In Slitherlink you stare at a grid made up of dots and the numbers 0, 1, 2, and 3 scattered about. Your goal is to join the dots around the numbers using the same number of lines as the number they are next to. The line snakes around the grid like ... a snake. Hudson published Puzzle Series Vol. 5: Slitherlink in Japan earlier this year and the game has received high marks from reviewers, including a 10/10 from Eurogamer.

It isn't known if Slitherlink DS will make its way out of Japan, but thanks to the world wide web and the humans that populate it, a Slitherlink-inspired game has been crafted in Flash, cleverly titled Slither Link.

Hudson Soft is giving Wii owners its second dose of Bonk with Bonk's Revenge. The Turbo-Grafx 16 platformer is due sometime next month on the Virtual Console, according to the publisher's official list. Also on the list for next month are Dragon's Curse, Bravoman, Battle Lode Runner and Shockman. Bravoman stands as only the second TurboGrafx-16 game from Namco Bandai, and only the fourth title not distributed by Hudson Soft.

The first title to be released, Dragon's Curse, is scheduled for next Monday, April 2. All titles will be priced the usual 600 Wii Points for purchase. Also known for next month are three from Sega, including a 2-dimensional Virtua Fighter 2. No word on what classic titles, if any, Nintendo will release in April.
