You complete Five Cells when every board cell belongs to exactly one pentomino-sized region and all local boundary counts are satisfied. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim.

Complete guide
Five Cells uses the independently implemented Nikoli Five Cells rules v1 profile (R459). Five Cells is a complete deterministic browser game whose distinct rules centre on a full partition into connected five-cell regions with clues reporting how many region boundaries touch their cells.
Five Cells opens from a versioned seeded position built for a full partition into connected five-cell regions with clues reporting how many region boundaries touch their cells. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
Every Five Cells action is checked against the current board, available material, and this defining restriction: each region contains exactly five orthogonally connected cells; diagonal contact never joins two cells into one region. Invalid, stale, or post-terminal actions leave the position unchanged.
You complete Five Cells when every board cell belongs to exactly one pentomino-sized region and all local boundary counts are satisfied. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim. Near the end of Five Cells, recount the remaining obligations needed until every board cell belongs to exactly one pentomino-sized region and all local boundary counts are satisfied. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.
A practical Five Cells plan is to preserve several legal continuations around a full partition into connected five-cell regions with clues reporting how many region boundaries touch their cells. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing. A common Five Cells error is to ignore the boundary rule that each region contains exactly five orthogonally connected cells; diagonal contact never joins two cells into one region. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
Five Cells has its own runtime and save identity because its rules require a full partition into connected five-cell regions with clues reporting how many region boundaries touch their cells.
each region contains exactly five orthogonally connected cells; diagonal contact never joins two cells into one region.
Five Cells stores its game ID, rules version, and seeded deal identity. Those values recreate the same opening locally without promising that the position is forced or winnable.
