Our most recent week focused on Pentominous puzzles can be found in this PDF.

We have a slight update to our schedule; the next regular week of puzzles, featuring Sudoku, will come next Sunday (and as a result we will not have any “gap weeks” as we continue with new puzzles for each of the next five weeks). This week, in place of the original Sudoku week, we will share a special Quintessence puzzle set from John Bulten which was a Sunday Surprise puzzle that grew into a full week’s experience. This starts over the next four days with four new shading puzzles/variations, building to a large challenge at the end of the week.
