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

  1. Selecting a light toggles itself and its orthogonal neighbors.
  2. Turn every light off to solve the puzzle.
  3. 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?
