How to play GlowSwitch

GlowSwitch is a free browser brain puzzle: every cell is either lit or dark. Tap a cell to flip its state and the states of the cells above, below, left and right. The goal is simple — leave the whole grid dark — but every press ripples outward, so you have to plan sequences instead of chasing single lights. Earn stars by finishing at or near par (the minimum move count).

Tips & strategy

• Work from one edge and chase lights toward the opposite side — random tapping usually adds moves.
• Par is the verified minimum; use Hint sparingly when stuck (three per board).
• Campaign unlocks in order: master 5×5 Pulse levels before Grid and Nova boards grow.

GlowSwitch FAQ

How do flips work?

A press toggles that cell and its four orthogonal neighbors. Corners and edges have fewer neighbors.

Can a board be unsolvable?

No — campaign levels and free boards are generated so a solution always exists.

Is GlowSwitch free?

Completely free in the browser: campaign, daily, and free play included.
