The Shikaku for September 17, 2026 — the classic size with real resistance.
Thursday pairs the classic 10×10 grid with a medium clue set — the board most regulars call the sweet spot. Expect a contested middle where two or three large clues compete for the same corridor.
The 10×10 collection has forty more at every tier. Every board is verified to a single solution, so a forced move always exists.
