KEEP THIS HANDY
Controls at a glance.
- Click a cell
- Toggle the selected cell and its orthogonal neighbors.
- Fire cells
- Track which cells remain on.
- Grid edge
- Only adjacent cells are intended to change; see the known bottom-row error below.
Extinguish every fire cell
Turn off all the fire cells on the grid. Selecting a cell also changes the neighboring cells immediately above, below, left and right.
How the game works
A neighboring cell that was on becomes off, and one that was off becomes on. The same action can therefore solve one part of the grid while changing another.
A practical starting point
Before selecting a cell, inspect its four neighbors and predict their new states. The creator explicitly relates the rules to the Lights Out puzzle.
What happens to your progress?
A portable save or cross-device synchronization is not established by the reviewed documentation. Check the original game before relying on a later return.
Check the save and backup guide ↗A FEW USEFUL ANSWERS
Before the next click.
What happens to an adjacent lit cell?
The creator says an on neighbor switches off, while an off neighbor switches on.
Why did a bottom-row move stop responding?
The published build has a boundary error that can interrupt a move when a bottom-row cell is selected.
Does this site’s Saved button keep my progress?
Saved keeps a link to this profile on your device. Game progress belongs to the game and its host.
