The Shikaku for September 18, 2026 — compact board, deep logic.
Friday's board is small but mean: a 7×7 with center-weighted clues that keep several candidates alive at once. Chain your deductions — claimed cells strand others, and stranded cells force placements.
If you enjoy this grade of resistance, the hard collection runs all the way up to 20×20. Compare times with a friend — everyone gets this same board today.
