How to play
- Goal
- Fill every row and column with the digits 1 through N exactly once, matching each edge clue's longest consecutive rising run.
- How it ends
- The chart ends when every visible rule is satisfied; mistakes can always be erased or undone.
- Record
- Your first unaided solve time is recorded for each chart.
- Fill each row and column with the digits 1 through N exactly once. There are no Sudoku boxes.
- Read a row from left to right and a column from top to bottom. Each edge clue gives its longest consecutive ascending run.
- A run grows only by exactly one. One, two, three counts three cells; separate runs are never added together.
- Select a blank cell and choose a digit. Printed digits cannot change. Erase, Undo and Redo let you repair entries.

- Combine two lines Use both the selected cell’s row clue and column clue.
- Check the longest run Shorter runs may coexist; only the longest must match the clue.
