really an awesome design! Agree with everyone - 5 shining stars for it. Thanks

Well-designed. I completed this yesterday, and I agree with the previous comments that the level gives away too much info. I tried some online calculators, and they're giving me an 8-digit code, so I just thought it was silly, so I tried another resource and I saw my mistake. And yes, the answer quite easy, but not too straightforward. Liked the words popping out when you input the right combination. I'd probably build one myself, as this looks fun to make.
