How to play
Mark the unique grid whose filled-cell runs match every row clue and every column clue exactly.
- The board starts as twenty-five unknown cells. Each row and column has an ordered list of clue numbers, where each number gives the length of one consecutive block of filled cells.
- Cycle any editable cell among unknown, filled, and crossed-out. Filled runs must appear in the clue order, and separate runs in the same line need at least one crossed-out cell between them.
- Mark the unique grid whose filled-cell runs match every row clue and every column clue exactly.
Strategy tips
- Start with lines whose clues nearly fill all five spaces, mark their forced overlap, and then use confirmed empty cells to split the remaining possibilities into shorter segments.
- Do not treat two clue numbers as one continuous block; the mandatory empty separator changes both the placement range and every crossing deduction.
- Before filling a final uncertain cell, recount each completed run in both directions so the last choice satisfies its row and its column simultaneously.
