Short Term Memory Test - Hard Version

I just copied the original and made it longer. There's no way to customise it at all other than number of answers.

This is just a custom quiz type which is only found in the original featured quiz. This functionality is only possible using this custom quiz type, and it uses â prebuilt list, which means the functionality only works (currently) with the short term memory word list embedded into the site's code.

I have considered adding the functionality separately, but haven't done so yet.
