Set 1vbizjy. 8 puzzles with an answer key, ready to print.

Expert puzzles are our hardest tier, with sparse grids usually in the mid-20s for givens. Expect to fill in every candidate and hunt for x-wings and swordfish. A printed copy and a sharp pencil is the classic way to tackle them.

Each free PDF has 8 puzzles, four to a page on US Letter paper, plus an answer key with every solution. Every puzzle has exactly one solution. A new set appears here every day, or you can grab a different set any time.
