Hahaha, I just noticed that I managed to write the correct word in the guesses, instead of "circuit". xD But it seems like nobody actually noticed?
No one noticed because no one remembers it's there or can be bothered to go to the first post to find out the used letters. It's much more convenient for the user to see them every couple of posts down here. Though, if you would have done that, we would've noticed your mistake...
That's it! Besides my April Fool's joke, this is the least amount of rupees I've ever needed to pay after a round of this.
