Daily Hard Jigsaw Sudoku

The daily hard jigsaw sudoku stretches the technique repertoire you've built up on Classic. With only 27–31 givens spread across irregular regions, you'll need hidden pairs, naked triples, X-Wing, and box-line equivalents adapted to the irregular regions. A fresh puzzle every visit means the daily hard jigsaw never repeats its tricks. The Show Candidates button is especially valuable on jigsaw because the eye can miss candidate placements inside a region that snakes across the grid. Sudoku247Online's region-aware solver verifies every hard daily jigsaw has a single unique solution by pure logic before it ships, so when you crack it, the answer is correct by construction.
