Slitherlink
A few days ago I finished a second book of Kakkuro (aka Kakuro), "Kakkuro #20" containing 95 puzzles that lasted me almost 2 months. It's about then that I heard somewhere that people who like Kakkuro tend to like another Nikoli game called "Slitherlink" and that's the next book that I got ("Slitherlink 18").
Slitherlink is also a game of numbers based in a grid, but instead of filling-in numbers like Sūdoku and Kakkuro, you trace a line along the grid's dots. The rules are simple:
- cells with a number (0 to 3) must have exactly that number of sides touched by a line,
- crossing lines or "T" shapes are not allowed, and
- the resulting line must be only one continuous (looping) line.
It's possible to solve these by using some logic. For example, if there's a "0" (no lines around it) next to a "3" (3 lines around it), only the side of the "3" facing the "0" will not have a line, the 3 other sides will have one. See examples of the game's flow, see this introduction at Nikoli's site. The logic rules listed at Wikipedia.
I got the book yesterday and spent maybe an hour or two completing 10 puzzles or so, and so far it's a lot of fun! It's easy to get trapped in places where it looks like the line would go one way but actually it's heading elsewhere.
Nikoli has 18 Slitherlink books, available for direct online order (international orders via PayPal).
