Conference Puzzles
I recently made some puzzles for the thirteenth Gathering 4 Gardner conference in Atlanta, and the MAA-NJ Rowan Burlington section meeting. When you build a puzzle around the specific title and/or date of the conference people see they're getting something designed for a single moment in time. Plus, the constraints on symbols can allow for some new innovation with the rules of the puzzle.
For the first of my G4G13 puzzles, incorporating the year 2018 was a natural way to get to the nine characters needed for sudoku. As there's only the one letter, we need not come up with an alphabetic rule. We can just allow the G's to fill in the remaining spots, which puts more pressure on the numeric clues, which are the distances between numbers. Including all the distances would make the puzzle way too easy, and thus I only included distances that were contained in the digits of the year.
High quality PDF for printing.
The other puzzles I created for this conference will be appearing in the G4G13 Exchange Book.
For the MAA-NJ puzzle, the alphabetic or numeric distance is given depending on whether adjacent cells contain two numbers or two letters. To make things more challenging, the distance is only given when it is less than or equal to 4 (for April.) Uniqueness is guaranteed by the "if and only if" statement in the instructions, as lack of a clue is a form of clue as well.
