Guess

from Simon Tatham's Portable Puzzle Collection


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!

More information

Most modern browsers should support WASM. I've had reports of success from:

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 guess.js and guess.wasm.


Try to guess the hidden combination of colours. You will be given limited information about each guess you make, enabling you to refine the next guess.

Drag from the colours on the left into the topmost unfilled row to make a guess; then click on the small circles to submit that guess. The small circles give you your feedback: black pegs indicate how many of the colours you guessed were the right colour in the right place, and white pegs indicate how many of the rest were the right colours but in the wrong place.
