Since my posting of two weeks ago, I've now retested all of the 120 puzzles in the book and settled on a final order. They are roughly sorted by difficulty, but this is somewhat subjective and I often tried to separate puzzles with particular features that might feel similar if done back to back. For reference, you have seen
#30 and
#108 in past weeks.
I'm not going to release too many more before-hand (6 out of 120 is probably my maximum), but to capture the missing quarters of the book, here are puzzles #3 (easy) and #86 (moderately hard) which use two different interpretations of a similar genre of visual theme. Enjoy!
Rules: Place a single digit from 1 to 9 into each cell so that no digit repeats in any row, column, or bold 3x3 region.
