BORN
SOLVED

Every copy existed once as a perfect solved whole. Then it was cut apart, scrambled and handed to you.

What it is

A puzzle that begins complete.

Born Solved is an edge-matching puzzle made from identical-looking hexagons. Plain black lines cross each edge, and every touching edge must continue those lines without interruption.

The design is printed as one continuous solved sheet before the pieces are cut apart and scrambled. The original manufactured arrangement is the born state: a known answer that can be regenerated from its seed.

Entropic Notation

The code is not what is drawn. It is where.

Fixed positions along an edge are called stations. A letter is the choice of stations crossed by visible lines. The stations never appear on the piece; only the crossings do.

Letters are distributed evenly and mirror-balanced, removing rare markings and making a flipped piece statistically ordinary.

The mathematics

The arrangement space grows beyond physical intuition.

For n hexagonal pieces, the raw arrangement count is n! × 12ⁿ. The factorial counts placements. The power of twelve counts six rotations on either face.

3×3≈10¹⁵9 pieces
8×8≈10¹⁵⁸64 pieces
16×16≈10⁷⁸³256 pieces
32×32≈10³⁷⁴⁵1,024 pieces

These are arrangements, not claimed solutions. The born state is the known manufactured answer.

Independent attack

The benchmark programme is being expanded.

CaDiCaL testing in progress

The earlier Kissat benchmark established a sharp increase in solving difficulty as puzzle size rose. A broader CaDiCaL test series is now being added so that solver version, hardware, variables, clauses, conflicts, decisions, propagations, memory, elapsed time and timeouts can be published together.

The revised hardness curve will appear here only after the expanded runs have been checked. Raw configuration counts, measured solver results and any extrapolation will be presented separately.
