You complete Pencils when every required cell belongs to a valid pencil or its lead and all numbered pencil lengths match their bodies. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim.

Complete guide
Pencils uses the independently implemented Nikoli Pencils rules v1 profile (R455). Pencils is a complete deterministic browser game whose distinct rules centre on one-cell-wide pencils formed from rectangular bodies and connected lead lines whose lengths and directions obey the printed clues.
Pencils opens from a versioned seeded position built for one-cell-wide pencils formed from rectangular bodies and connected lead lines whose lengths and directions obey the printed clues. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
Every Pencils action is checked against the current board, available material, and this defining restriction: pencil bodies may not overlap, and each lead must leave the sharpened end in its permitted direction without branching. Invalid, stale, or post-terminal actions leave the position unchanged.
You complete Pencils when every required cell belongs to a valid pencil or its lead and all numbered pencil lengths match their bodies. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim. Near the end of Pencils, recount the remaining obligations needed until every required cell belongs to a valid pencil or its lead and all numbered pencil lengths match their bodies. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.
A practical Pencils plan is to preserve several legal continuations around one-cell-wide pencils formed from rectangular bodies and connected lead lines whose lengths and directions obey the printed clues. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing. A common Pencils error is to ignore the boundary rule that pencil bodies may not overlap, and each lead must leave the sharpened end in its permitted direction without branching. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
Pencils has its own runtime and save identity because its rules require one-cell-wide pencils formed from rectangular bodies and connected lead lines whose lengths and directions obey the printed clues.
pencil bodies may not overlap, and each lead must leave the sharpened end in its permitted direction without branching.
Pencils 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.
