## What is Light Up Logic Puzzle2026?

Light Up Logic is a fully offline logic puzzle game. Place bulbs on the grid to illuminate every empty cell, while preventing bulbs from shining on each other and satisfying the numbers shown on black cells.

Core features include multiple difficulty levels, candidate marks, error checking, logical hints, timer statistics, and local progress saving. The game requires no login, does not connect to the internet, and does not collect user data, making it ideal for quiet deduction during commutes, bedtime, or short breaks.
