Have a look at the Captcha and Text Image modules. It would be very easy to implement a hook for the captcha module and then riddles are integrated into Captcha. No need to duplicate tons of work.

Thanks for your input and you are absolutely right. There is really no point in implementing all these form hooks again since the Captcha module itself is so simple.

I've updated the module to require Captcha. Those who prefer the old one can use the older version.

Also changing the name to "Captcha Riddler" - More informative :)
