All-TimeThe daily expert jigsaw sudoku is the hardest tier we generate. With 24–26 givens spread across nine irregular regions, almost every move comes from technique rather than scanning — swordfish, XY-Wing, Unique Rectangle, and chains all show up regularly, often forced through the irregular region shape. Sessions take real time; even confident solvers spend 30–60 minutes here. A fresh puzzle every visit means the daily expert jigsaw is genuinely a daily trial. Sudoku247Online runs every expert daily through the same region-aware uniqueness checker as the lower tiers, so the answer is always pinned to a single legal solution — no guesswork required, just patient deduction.
