NumGrid
Friday NumGrid puzzles run at the harder end of the weekly difficulty curve. Puzzle #28 from Friday, June 19, 2026 reflects that calibration — 5-digit targets with more challenging digit patterns, including frequent repeated digits and patterns that minimize the per-guess information gain from common openings.
Mid-month NumGrid puzzles run the standard calibration for their day of the week. Puzzle #28 is one of those — neither early-month restart material nor late-month closing material, just the representative middle-of-the-month difficulty band.
