Thanks for the compliment. It predates the existence of WebKit on Windows and also my ownership of a Mac, so it didn’t get fully tested. Middle-click does work on IE and Firefox on Windows. I did do enough testing on the Mac at the time to find a bug in Mozilla where it misreports the mouse button in mousedown and mouseup events ( https://bugzilla.mozilla.org/show_bug.cgi?id=264922 ) and thought I’d worked around it. I’m sufficiently interested now that I will revisit the code and try and fix it.

Minefields are generated entirely at random. It does follow the winmine convention of preventing the first cleared space from being a mine but simply reassigns it to a random space on the grid, not the top left corner. That was a deliberate choice because I didn’t like the idea of it going in the top left, but I suppose it violates the aim of trying to be a proper winmine clone.

As ever with 5-year-old code, I’m slightly embarrassed by it but shall manage to resist the temptation to rewrite it all :)

That is by far the best web winmine clone I’ve encountered.

No mouse events at all seem to work in WebKit (not even left-click). I tried it in Firefox though and was really impressed. I did notice that it doesn’t capture middle-click (which, in Win 3.1 winmine.exe at least, performs the same action as left-right-click). That may be Mac Firefox specific? I do see middle-click code in the source.

Timing is of course an issue with any time-sensitive Javascript-based app, but I’m sure it’s accurate enough for this purpose—but I’ve also heard tell that the original winmine’s timing was itself inaccurate. I can’t find any sources to back that up now though.

I’m curious how you’re generating minefields. Do you follow winmine’s rules that prevent the first cleared space from being a mine (this seems to be the case from playing with it), and if it is a mine, move that mine to as close to the top left corner as possible?

I know that winmine also has only a limited set of predefined fields, but even as obsessed as I am I would never expect anyone to reproduce that.

Sorry for the nitpicky questions, I’m just really impressed and curious.

Very impressively done!
