Daily Jigsaw Sudoku

The daily jigsaw sudoku is the gentlest way to make the irregular-region variant a habit. Jigsaw swaps the standard 3×3 boxes for nine irregularly shaped regions of nine cells each, drawn with heavier borders on the board; row and column rules are unchanged. At the easy tier most cells start filled, so the standard naked-single and hidden-single moves you already know from Classic carry most of the puzzle — the only new habit is tracing each region with your eye before you start. A fresh puzzle and a fresh region layout every visit means the daily jigsaw never repeats. The easy tier comfortably solves in 8–15 minutes once you're scanning the irregular regions as fluently as 3×3 boxes.
