So does this sometimes reach an unsolvable state? I have a captcha whose digits sum up to 24, a condition that all digits should sum up to 25, and the best chess move is Ne6+ (accepted), but there's no way to get all digits to sum to 25!

m3588 is the captcha and Ne6+ is the chess move in the above

I've also tried putting something like -5 in the hope that it recognizes negative numbers, but no luck!



When you break the captcha rule, you can re-select the captcha. You want to keep re-rolling till you find a low number combo. There are a few rules where you can re-roll to get a better random number. In general, it gets harder and harder to stay under the 25 limit as you progress.


You can refresh the captcha to make it work.
