It should be playable with any "6.x" browser or later (IE6, Netscape 6, and everything after).
So far, it has been tried with the following browsers:
- Firefox 2, Firefox 3.6, Firefox 4, up to Firefox 20
- Internet Explorer 6 (doesn't support <canvas>, but we can emulate it)
- Internet Explorer 8
- Iron 10.0.650.0 (a Google Chrome variant)
- MicroB (the Mozilla variant running on the Nokia N900 smartphone)
- Mozilla 1.2 (yes! from 2002! The only thing missing here is <canvas>)
- Opera 11.01
The formatting may look broken in IE6. Sometimes I fix it, sometimes I don't.
Some browsers (at least older versions of links, lynx) do not correctly handle our redirects ("post redirect get" pattern). Choose "no" when they ask you to submit a form for the third time.
Pre-"6.x" browsers (e.g. IE5, Netscape 4.01) are not supported. These browsers either lack required features, or claim to support them but fail when asked to actually do them.
