Grid Logic Puzzle - Brain Teaser

What You Actually Do

Each level presents a grid containing movable pieces and target lights. You select a piece and slide it along straight paths until it hits an obstacle or the grid edge. As it travels, the piece leaves a trail of energy. A light activates only when it receives the correct amount of energy. Overshoot or undershoot, and the level may need a restart. The loop is simple: observe, slide, check the result.

Why the Energy Trail Matters

The trail mechanic is what separates this from a standard sliding puzzle. You are not just rearranging pieces into positions; you are distributing a limited resource across the grid. Every move commits energy to a path, so a route that lights one target might drain a piece needed elsewhere. Efficient solutions require thinking about the whole board before the first slide.

Designed for Unhurried Thinking

There are no timers, countdowns, or reaction-based challenges. The game is built around pure logic, so you can sit with a layout, test a route, and restart without penalty. Grid layouts grow more complex as you progress, but the difficulty comes from the puzzle design rather than external pressure. Progress saves automatically, and the game works offline after the initial load.

Controls and Accessibility

Drag-and-slide interactions work on both desktop and mobile. The controls stay out of the way: select a piece, drag along a valid path, release. Because each puzzle has a single solution, there is no ambiguity about whether a level is solvable. The game is family-friendly and has no ads or in-app purchases, so nothing interrupts a solving session.
