What is distinct here
Glow Grid is a compact toggle puzzle where selecting one light also changes its orthogonal neighbours. The board exposes every state and move, turning a familiar light-switch mechanic into a transparent planning challenge.
Rules
- Selecting a light toggles itself and its orthogonal neighbors.
- Turn every light off to solve the puzzle.
- Every puzzle is created by applying valid moves to a solved board, so it always has a solution.
Strategy tips
- Work from the top row downward so solved rows stay untouched.
- Corner lights affect fewer cells and are useful for reading the pattern.
What we tested
Levels are produced from known press patterns so a solution always exists. QA verifies neighbour boundaries, repeated toggles, solved-state detection, move count, local best score, arrows plus Enter, direct touch, pause and restart.
Frequently asked questions
Is every Glow Grid puzzle solvable?
Yes. Each puzzle begins from a solved grid and is scrambled only with legal moves.
How is the score calculated?
You start from 1,000 points; extra moves and elapsed seconds reduce the final score.
