Gridisco: Daily Logic Puzzle

Turn off all the lights. Sounds easy — until every tap flips the cell you touch and its neighbors too. Gridisco is a free puzzle game built around the classic Lights Out mechanic on a 5×5 grid. Tap cells to toggle them on or off; adjacent cells (up, down, left, right) flip as well. Clear the entire board to win. Simple to learn, surprisingly strategic to master.
