We have a winner!

My associate Mr Curtis and I have performed our monthly random drawing from among all those who sent us the correct final answer to this Addendum, and the lucky winner is ...

Mr Robert Herceg of Parkersburg, West Virginia!
For his prize, Mr Herceg has received a free copy of the puzzle X Games, cleverly designed and manufactured by Mr Curtis!

Ada has published a book!

Yes, that's right: Ada has created a book collecting the first twenty-four of her ænigmas, along with author commentaries, full solutions, explanations of all of the Easter eggs, and a host of other fun features!

I pray you will not hesitate to contact my associate, Pavel Curtis (at pavel@pavelspuzzles.com) for immediate relief. If there is sufficient collective need, I am more than open to making available a page of pedagogical aids.
With sincere hopes that this Addendum will provide you with delight and edification,
