Rules and objective
Turn off the complete 3×3 board using cross-shaped toggles. A tap changes its own cell plus valid orthogonal neighbors; row boundaries prevent accidental wraparound.
How scoring works
Finishing in fewer moves produces a higher result, with a minimum completion award retained. Scores are saved only in this browser's local storage, so changing devices or clearing site data starts a new local record.
What we checked in this build
We verified corner, edge and center behavior separately and confirmed that Reset restores the original puzzle.
This note describes the Starbox implementation rather than the rules of every similarly named game elsewhere.
Know exactly what one tap changes
A tap flips the chosen light and its orthogonal neighbors—up, down, left, and right when those positions exist. Diagonal lights do not change. Corners affect fewer cells than center positions, so the same-looking local problem may need a different move near an edge.
Use cancellation
Tapping a position twice returns every affected light to its previous state. Therefore a useful solution never needs the same square twice; the two taps would cancel. Treat each position as a yes-or-no decision. This reduces frantic experimentation and makes it possible to replay a promising sequence.
Chase lights row by row
After choosing taps in the first row, inspect the light directly below each first-row cell. If it remains on, tap the cell beneath it in the next row. That tap is the only later move that can switch the light above without disturbing earlier rows too widely. Continue downward, then evaluate the final row.
Record the first-row choice
If the last row is not cleared, the error often lies in the starting pattern rather than the chase procedure. Note which first-row squares you tapped and change that choice systematically on the next attempt. A repeatable method turns a confusing board into a small set of starting cases.
