The daily tangram for September 18, 2026 — a compact 5×6 silhouette, the same for every player and solvable with all seven tans.
The outline stretches 5×6 on the lattice, compact enough that your first instinct about the large triangles may be wrong. It's a hard board: no internal lines and a deceptive outline that punishes early commitments, so stay flexible. 5 of the seven tans are rotated in the reference dissection; keep turning pieces until the edges finally agree. The parallelogram keeps its natural face today; no flipping is needed in the reference dissection.
Place the two large triangles before anything else — together they cover half the total area, and a wrong home for either unravels the rest. Every daily stays playable forever at its own URL. New to the rules? See the how-to-play guide. Missed a day? Browse the archive.
