If you've been reading this message for more than a second or two, then this WebAssembly puzzle doesn't seem to be working in your web browser. Sorry!
Most modern browsers should support WASM. I've had reports of success from:
More information
If this puzzle isn't working in one of those browsers (or a later version), check to see whether you have any local configuration that might have turned off WebAssembly completely, or some kind of blocking software that might have prevented the WASM code from being downloaded in the first place.
(For example, in Firefox, it's possible to turn off WASM completely
by setting javascript.options.wasm to false
in the about:config interface. If you've done that, or
something analogous in another browser, this puzzle won't run.)
In other browsers, the problem might be that WebAssembly isn't supported at all (for example, Internet Explorer 11), or that a browser update is needed.
If you think that your browser should support WebAssembly, but this puzzle still isn't running, then please report the problem, including as much diagnostic information as you can find.
In particular, try opening your browser's Javascript error console and then reloading this page, and tell me if it reports any error messages.
Also, if your browser has a network diagnostic tab, try the same
experiment, to make sure it is successfully loading both of the
auxiliary files solo.js and
solo.wasm.
Fill in a number in every square so that every number appears exactly once in each row, each column and each block marked by thick lines.
To place a number, click in a square to select it, then type the number on the keyboard. To erase a number, click to select a square and then press Backspace.
Right-click in a square and then type a number to add or remove the number as a pencil mark, indicating numbers that you think might go in that square.
When you master the basic game, try Jigsaw mode (irregularly shaped blocks), X mode (the two main diagonals of the grid must also contain every number once), Killer mode (instead of single-cell clues you are given regions of the grid each of which must add up to a given total, again without reusing any digits), or all of those at once!
