NumGrid
Weekend NumGrid puzzles are calibrated to the hardest tier in the weekly rotation. Puzzle #58 (Sunday, July 19, 2026) is one of those — 5-digit targets, frequent repeated digits, and digit distributions chosen specifically to defeat naive opening strategies. Expect longer solve times, higher chance of needing the full guess budget, and a higher rate of unsolved finishes than any other day of the week.
Mid-month NumGrid puzzles run the standard calibration for their day of the week. Puzzle #58 is one of those — neither early-month restart material nor late-month closing material, just the representative middle-of-the-month difficulty band.
