Theme: Good Odds
Author/Opus: This is the 49th puzzle from our contributing puzzlemaster Palmer Mebane.
Rules: Place a digit from 1 to 9 into each empty cell so that, for each row above the bottom row, every digit is the sum or difference of the two digits immediately below it. Rows marked in gray cannot have repeated digits; rows in white must have at least one repeated digit.
Also see this example:
Answer String: Enter the digits in the marked rows from left to right, separating each row with a comma.
Time Standards (highlight to view): Grandmaster = 7:00, Master = 15:00, Expert = 30:00
This was tough. I used the knowledge that there was a unique solution to rule out possibilities in several places, which makes me feel a bit dirty.
Heh, I did the same and felt the same!
Hi there, is there a way for me to view the puzzle? I tried to subscribe, but it wouldn’t let me. I’m trying to make a react app using this puzzle idea 🙂 thanks!
There is no direct way to get the old subscriber puzzles, but we are starting to work on a new e-book which will release all of these puzzles again. Pyramid is not a standard style for us on this site but can be found elsewhere.
