Setup and opening position
Every orthogonal pair of neighboring cells has one undecided internal edge. The region-size clue is three, and a bounded solver selects enough fixed edges for one partition.
Palisade Puzzle
Partition all nine cells into three connected regions of exactly three cells by assigning every internal edge correctly.

How to play
Partition all nine cells into three connected regions of exactly three cells by assigning every internal edge correctly.
- Every orthogonal pair of neighboring cells has one undecided internal edge. The region-size clue is three, and a bounded solver selects enough fixed edges for one partition.
- Mark an editable internal edge as wall or open, or clear it. Open edges join their two neighboring cells; walls separate those cells into different components.
- Partition all nine cells into three connected regions of exactly three cells by assigning every internal edge correctly.
Strategy tips
- Track component sizes as open edges are added, closing walls around any component that reaches three and rejecting joins that would create a component larger than three.
- A group of three touching cells is not finished if an unmarked edge still opens into a fourth cell, and disconnected cells cannot form one region by count alone.
- When two components remain incomplete, compare their available boundary edges and close any join that would exceed size three before opening the forced connector within each region.

Rules, scoring, and strategy
Palisade Puzzle is a complete browser implementation with its own versioned rules profile. Choose walls and openings on the twelve internal edges of a three-by-three grid so the cells split into connected regions containing exactly three cells each.
Legal moves and game flow
Mark an editable internal edge as wall or open, or clear it. Open edges join their two neighboring cells; walls separate those cells into different components.
Winning and terminal positions
Partition all nine cells into three connected regions of exactly three cells by assigning every internal edge correctly. When two components remain incomplete, compare their available boundary edges and close any join that would exceed size three before opening the forced connector within each region.
Practical strategy
Track component sizes as open edges are added, closing walls around any component that reaches three and rejecting joins that would create a component larger than three. A group of three touching cells is not finished if an unmarked edge still opens into a fourth cell, and disconnected cells cannot form one region by count alone.
