How to Use
- Select your grid size — 6×6 uses digits 1–6, 9×9 uses 1–9
- Set compartment length — count the white cells between black cells
- Mark any blocked digits — digits shown on black cells in that row or column are blocked from white cells in the same line
- All valid consecutive sequences appear instantly
- Check Insights for digits that must or cannot appear across all valid sequences
Blocked Digits
In Straights, a digit printed on a black cell is "blocked" — it cannot appear anywhere else in that row or column. When working out what can go in a compartment, exclude any blocked digits from that row or column. Tap a digit in the Blocked digits row to mark it as blocked.
Solving Strategies
- Start with single-cell compartments — the digit is always determined by row and column eliminations
- Short compartments with many blocked digits often resolve quickly
- Use Insights to find digits locked into a compartment regardless of sequence order
- Compare compartments in the same row or column to eliminate shared candidates
What is Straights?
Straights is a logic puzzle on a grid of black and white cells. White cells must be filled with digits so that each row and column contains no repeats. White cells within a compartment (a run between black cells) must form a consecutive set — like a straight in poker — though not necessarily in order. Black cells may contain digits that block those digits from the rest of the row or column.
