Slitherlink puzzle
The author of many logic puzzles belongs to the Japanese company Nikoli, and the game Slitherlink is no exception. After its publication in 1989, it gained popularity in Japan and quickly spread internationally.
Today it is played in all civilized countries, knowing this puzzle both by its original name - Slitherlink (スリザーリンク), and by alternative ones: Fences, Loop the Loop, Takegaki, Ourboros, Rundweg, Suriza, Dotty Dilemma, Loopy.
Western interpretations of the game are not much different from the original: the basic rules remain unchanged. In different versions, only the design and size of the playing field changes.
Game history
The golden age, or rather, the golden decade of logical digital puzzles occurred at the turn of 1980-1990, when a special section dedicated to them appeared in the Japanese magazine from the publishing house Nikoli.
At first it was filled with classic Western and Asian puzzles, and then new ideas began to be introduced - with the help of the magazine's readers. This is how many famous games saw the light, including Slitherlink, which was based on letters from two readers: Yuki Todoroki (轟由紀) and Renin (れーにん, “Lenin” in Japanese).
Combining their ideas, the Nikoli staff published the first and final version of Slitherlink in issue 26 of Puzzle Communication Nikoli magazine in June 1989. It became one of the calling cards of the magazine, because until then the general public had not seen such puzzles in printed form.
It's worth noting that the original version of Slitherlink from Ranin's letter involved placing points around a field element and specifying the number of edges inside it. It was not necessary to close the ring around all the numbers. And when combined with the version from Yuki Todoroki, the game was changed, and it became possible to leave empty squares without numbers - with the only correct solution. From that moment on, it became mandatory to close the lines, that is, relatively speaking, to build a solid wall around the numbers.
Like most other puzzle games, Slitherlink has been ported to various digital platforms. The first version was Slither Link in 2000, released for the WonderSwan handheld console by Bandai. Already in 2001, Slither Link, along with such famous games as Sudoku and nonograms, was included in the collection Loppi Puzzle Magazine: Kangaeru Puzzle for Game Boy from Nintendo, and a little later it was released on cartridges for the Nintendo DS console.
In 2006, this game was also included in Nikoli's Brain Buster Puzzle Pak, and six months later, in June 2007, it was released along with other games in the United States.
Since then, Slitherlink, constantly undergoing visual changes, has been regularly published under different names on a variety of platforms: from computers to portable gadgets.
