- Rows and columns are divided into compartments of white squares.
- Use single numbers to complete a straight for each compartment.
- A straight is a set of numbers with no gaps and in any order.
- No single number can repeat in any row or column.
- Clues in black cells remove that number as an option in that row and column,
and are not part of any straight
- Additionally, for B-Str8ts numbers in each 3x3 box must be unique. Guide
Best of luck!
