Sudoku has become such a mainstay puzzle, a common find in newspapers and magazines, that it’s easy to forget that it wasn’t always this way. While Sudoku got its start as Number Place in the pages of Dell Magazines back in the late 1970s, it wasn’t until mid-2006 that the logic puzzle became an all-consuming worldwide fad, blowing up in a way no puzzle had since the crossword in the 1920s.

The fad has subsided a bit, but Sudoku is still with us, exercising the minds of millions of solvers. But for lovers of logic puzzles, Sudoku’s greatest impact is in how it inspired dozens if not hundreds of related puzzles, all with their own devious rules. If you love Sudoku but have wondered now and again what else there might be for you out there, read on.

A great place to start is at the blog of Grandmaster Puzzles, where Thomas Snyder and his crew of constructors post a new logic puzzle six days a week. It’s a great place to start, that is, if you can overcome the intimidation factor, which is significant. Take a look at that menu of puzzle types on the left! What *are* all those? Statue Park? Cross the Streams? Kakuro, Kurotto, Kuromasu?

Deep breaths. We’re going to give you a few good places to start, and then if you like what you see, you can branch out from there.

**Star Battle:** As simple to grasp as a logic puzzle gets, which is why you’ll sometimes see this type in other venues, notably in the *New York Times* under the (bizarre) name of “Two Not Touch.” All you need to do is place some number of stars (usually two) in every row, every column, and each bordered region so that stars are never right next to each other, even diagonally. Here are Grandmaster Puzzles’s easiest Star Battle puzzles, an excellent place to get started.

**Fillomino:** A step up in trickiness, but still a good type for newbies. You’ll need to divide up a Fillomino grid into irregularly shaped regions according to the following few rules: First, the area of each region must be equal to the numbers within it — so, for example, a region of three cells has to contain three 3s. (You’ll never have a region with different digits within it.) Second, no two regions of the same size may share an edge. Third… there is no third. That’s it, those are the two rules. See?

One thing newcomers to this puzzle type need to watch out for: Not every region in a completed puzzle will encompass one of the numbers given to you at the start. You might have a “hidden” region that is only logically revealed as you figure out the regions around it. Once you’re prepared for that possibility, though, this puzzle is reasonably straightforward. Here are the easiest Grandmaster Filliominos.

**LITS: **Looks a lot like Star Battle, right? Sure. But this time around you’re not placing stars. Instead, you will shade in *exactly* four spaces in each region, so that when you’re done, all of the shaded cells make a connected path through the grid. (That is, you can reach any shaded cell from any other shaded cell.)

There are only four shapes you can make with shaded cells: L, I, T, and S. (Hey, I think I figured out where this puzzle’s name comes from!) In the completed grid, no two shapes of the same type can share an edge. Also, no four shaded cells can form a 2×2 square. Those extra rules will definitely give you pause as you go about filling a grid. Try some easy LITS puzzles here.

**Masyu: **We’ll conclude with a slightly trickier puzzle to grasp — but only slightly. In Masyu, you’ll draw a loop that goes through some number of cells in the grid (not necessarily *every* cell). The white circles and the black circles obey different rules:

*Black Circles: *The path *must* turn here, and then the path must *not* turn in either adjacent cell.

*White Circles: *The path *must* go straight through these circles without turning. Also the path must turn in the cell just before and/or just after a white circle.

Not a ton of rules, but they can be a little confusing for the newbie. Still, this is a satisfying type. Try some easy examples here.

Nobody is going to enjoy every logic puzzle type. I personally will wave away all attempts to get me to solve the math-oriented Kakuro — even though I enjoy both TomTom (an improvement on KenKen) and Japanese Sums, both of which are also math-based. Why? Who knows? We are what we are. So go explore the puzzle types above and then dive into Grandmaster’s full list of logic types. Your next favorite puzzle is in there somewhere.
