Complete guide
Chained Block uses the independently implemented Nikoli Chained Block rules v1 profile (R456). Chained Block is a complete deterministic browser game whose distinct rules centre on shaded blocks of prescribed size joined into one diagonal chain while equal-shaped blocks are forbidden from touching orthogonally.
Chained Block opens from a versioned seeded position built for shaded blocks of prescribed size joined into one diagonal chain while equal-shaped blocks are forbidden from touching orthogonally. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
Every Chained Block action is checked against the current board, available material, and this defining restriction: distinct blocks may connect only through the allowed corner relationship; an edge contact merges them and changes their size. Invalid, stale, or post-terminal actions leave the position unchanged.
You complete Chained Block when all clues belong to correctly sized shaded blocks and the complete collection forms the required connected chain. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim. Near the end of Chained Block, recount the remaining obligations needed until all clues belong to correctly sized shaded blocks and the complete collection forms the required connected chain. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.
A practical Chained Block plan is to preserve several legal continuations around shaded blocks of prescribed size joined into one diagonal chain while equal-shaped blocks are forbidden from touching orthogonally. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing. A common Chained Block error is to ignore the boundary rule that distinct blocks may connect only through the allowed corner relationship; an edge contact merges them and changes their size. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
Chained Block has its own runtime and save identity because its rules require shaded blocks of prescribed size joined into one diagonal chain while equal-shaped blocks are forbidden from touching orthogonally.
distinct blocks may connect only through the allowed corner relationship; an edge contact merges them and changes their size.
Chained Block 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.
