Strategy guides
Short, opinionated tips from solvers who routinely top the leaderboard. Hover the grids — they subtly respond so the page feels a little playable.
Opening moves
Corner clues have the fewest valid rectangles. Locking a corner early prunes the board for every neighbour — you rarely need a redraw.
Start where the grid gives you the tightest box — usually a corner 2×2 or edge strip.
Geometry sense
Flexible means “tall rectangle or wide rectangle,” not an L-shape. Hover the cards below: same clue — two legal orientations until neighbours force one.
Peek at bordering clues — the orientation that steals fewer of their rectangles wins.
Counting
A tagged “6” on a wide clue is factor math: valid placements are rectangles where width exceeds height — often 3×2 or 6×1, rarely anything else once the perimeter is scanned.
3×2 wide region: six cells, clue sits inside the patch — same idea on the full board at scale.
Pattern recall
On larger boards, designers often balance mass from corner to corner. Spotting a 2×2 in one corner can shortcut the opposite quadrant before you read every clue twice.
Mirrored corners on a 6×6 — sketch the opposite patch early and adjust when a neighbour says no.
