How to play

The winning condition for Renban is precise: every cell, edge, region, and fixed clue satisfies the consecutive room latin completion test. No hidden solution values are printed to justify the result; the rules engine validates the submitted position.

  • Before the first move in Renban, identify which marks are givens and which controls are decisions. Complete a Latin grid in which every outlined room contains an unordered run of consecutive, nonrepeating values. 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. Complete a Latin grid in which every outlined room contains an unordered run of consecutive, nonrepeating values. The runtime validates the resulting state before it records a move or opens a new undo branch.
  • The winning condition for Renban is precise: every cell, edge, region, and fixed clue satisfies the consecutive room latin completion test. No hidden solution values are printed to justify the result; the rules engine validates the submitted position.

Strategy tips

  • Find the minimum and maximum possible value for each room, then intersect that consecutive range with the unused candidates in every crossing row and column.
  • Placing consecutive values in sorted spatial order adds a rule that does not exist; a Renban room needs the set, not a visual sequence.
  • 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 consecutive room latin completion test. A locally attractive move can still break a distant constraint.

Rules, scoring, and strategy

Renban uses the independently implemented Renban consecutive room latin rules v1 profile (R662). Renban changes familiar play through a specific constraint: Complete a Latin grid in which every outlined room contains an unordered run of consecutive, nonrepeating values.

Setup and opening position

Before the first move in Renban, identify which marks are givens and which controls are decisions. Complete a Latin grid in which every outlined room contains an unordered run of consecutive, nonrepeating values. 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. Complete a Latin grid in which every outlined room contains an unordered run of consecutive, nonrepeating values. 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 Renban is precise: every cell, edge, region, and fixed clue satisfies the consecutive room latin 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 consecutive room latin completion test. A locally attractive move can still break a distant constraint.

Practical strategy

Find the minimum and maximum possible value for each room, then intersect that consecutive range with the unused candidates in every crossing row and column. Placing consecutive values in sorted spatial order adds a rule that does not exist; a Renban room needs the set, not a visual sequence.

Questions players ask

How does play in Renban change when players account for unordered consecutive sets inside rooms?

Find the minimum and maximum possible value for each room, then intersect that consecutive range with the unused candidates in every crossing row and column. This matters specifically because complete a Latin grid in which every outlined room contains an unordered run of consecutive, nonrepeating values.

Why can a locally legal-looking plan fail in Renban?

Placing consecutive values in sorted spatial order adds a rule that does not exist; a Renban room needs the set, not a visual sequence. Recheck the legal boundary before choosing a replacement move.

Which obligations must all agree at the end of Renban?

Success in Renban requires that every cell, edge, region, and fixed clue satisfies the consecutive room latin 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.
