Quadrata: A Free Puzzle Blog

Post by Quadrata » Wed 12 Aug, 2020 6:27 pm

Just wanted to let everyone here know about a puzzle website that I maintain. I post new original puzzle varieties there about twice a month. Today I posted three Sudoku variants where the clues are the greatest common divisors of the numbers in adjacent cells. This puzzle is below, and the solution and more info can be found at the blog at:

Here are some small puzzles based around divisibility, with arrows revealing which number divides which. Dots indicate that neither divides the other. The first puzzle is solved to give you a visual instruction. The next three puzzles increase with difficulty as they go.

Here's a 9x9 Sudoku where the clues tell you what the sum is of the two adjacent cells. The catch is that the numbers are only given when they are even. Thus a numberless dot reveals that the sum is odd without telling you what that sum is.
