This next week contains a set of puzzles based on a simple variation suggested by Grant Fikes, author of the Monday puzzle, where each puzzle must have an even number of features like shaded cells in each row and in each column. We think you’ll enjoy this variation and the variety of ways our authors took advantage of the new logical possibilities.
