How to play

The winning condition for Canal View is precise: every cell, edge, region, and fixed clue satisfies the connected water directional sight completion test. No hidden solution values are printed to justify the result; the rules engine validates the submitted position.

  • Before the first move in Canal View, identify which marks are givens and which controls are decisions. Canal cells form one shaded network, unshaded cells contain no two-by-two block, and each clue totals visible canal cells along four rays. The browser stores that distinction with the seeded opening so a restart never changes the puzzle or deal.
  • Use the live board controls to change one legal decision at a time. Canal cells form one shaded network, unshaded cells contain no two-by-two block, and each clue totals visible canal cells along four rays. The runtime validates the resulting state before it records a move or opens a new undo branch.
  • The winning condition for Canal View is precise: every cell, edge, region, and fixed clue satisfies the connected water directional sight completion test. No hidden solution values are printed to justify the result; the rules engine validates the submitted position.

Strategy tips

  • Use directional clues to bound the canal along four rays, then connect forced shaded segments while reserving breaks that prevent a two-by-two white pool.
  • Counting only contiguous shaded cells misreads a sight clue; every visible canal cell on all four rays contributes under the published rule.
  • Use undo to compare the last branch if two completions look plausible, then recheck the exact requirement: every cell, edge, region, and fixed clue satisfies the connected water directional sight completion test. A locally attractive move can still break a distant constraint.

Complete guide

Rules, scoring, and strategy

Canal View uses the independently implemented Canal View connected water directional sight rules v1 profile (R642). Canal View changes familiar play through a specific constraint: Canal cells form one shaded network, unshaded cells contain no two-by-two block, and each clue totals visible canal cells along four rays.

Setup and opening position

Before the first move in Canal View, identify which marks are givens and which controls are decisions. Canal cells form one shaded network, unshaded cells contain no two-by-two block, and each clue totals visible canal cells along four rays. The browser stores that distinction with the seeded opening so a restart never changes the puzzle or deal.

Legal moves and game flow

Use the live board controls to change one legal decision at a time. Canal cells form one shaded network, unshaded cells contain no two-by-two block, and each clue totals visible canal cells along four rays. The runtime validates the resulting state before it records a move or opens a new undo branch.

Winning and terminal positions

The winning condition for Canal View is precise: every cell, edge, region, and fixed clue satisfies the connected water directional sight completion test. No hidden solution values are printed to justify the result; the rules engine validates the submitted position. Use undo to compare the last branch if two completions look plausible, then recheck the exact requirement: every cell, edge, region, and fixed clue satisfies the connected water directional sight completion test. A locally attractive move can still break a distant constraint.

Practical strategy

Use directional clues to bound the canal along four rays, then connect forced shaded segments while reserving breaks that prevent a two-by-two white pool. Counting only contiguous shaded cells misreads a sight clue; every visible canal cell on all four rays contributes under the published rule.

Questions players ask

How does play in Canal View change when players account for four-ray canal sight counts?

Use directional clues to bound the canal along four rays, then connect forced shaded segments while reserving breaks that prevent a two-by-two white pool. This matters specifically because canal cells form one shaded network, unshaded cells contain no two-by-two block, and each clue totals visible canal cells along four rays.

Why can a locally legal-looking plan fail in Canal View?

Counting only contiguous shaded cells misreads a sight clue; every visible canal cell on all four rays contributes under the published rule. Recheck the legal boundary before choosing a replacement move.

Which obligations must all agree at the end of Canal View?

Success in Canal View requires that every cell, edge, region, and fixed clue satisfies the connected water directional sight completion test. The game declares completion only after all interacting restrictions agree at the same time. Undo and redo expose alternative branches without revealing an authored answer.
