Logic Grid Light Puzzle

Matching Light to a Target

Each puzzle presents a target image on a grid. Your job is to make the grid match that image exactly. You have a set number of moves, and every action changes the board. The challenge is not just seeing the difference between your grid and the target, but finding the shortest sequence of moves that closes the gap.

Three Moves, One Goal

You interact with individual squares using three actions: add light, subtract light, or invert the light of a square. Adding and subtracting adjust a single square's brightness, while inverting flips its state. The invert option is especially useful when a whole region needs to change at once, since it can flip several squares in a single move if they share the same current state. Choosing between these three actions is the core decision you make on every turn.

Planning Without a Timer

There is no time pressure. You can study the target image for as long as you like before committing to a move. The game also lets you undo moves, so experimenting with a sequence does not permanently ruin your attempt. This makes the puzzle about planning and spatial reasoning rather than reflexes or speed.

Progression and Accessibility

Puzzles become more complex as you advance, requiring you to think further ahead and recognize patterns such as symmetry or repeated shapes. The controls stay simple throughout, and the clean grid display keeps the focus on the logic. Because the game contains no violence or mature content, it suits players of all ages, from beginners to experienced puzzle solvers.
