Lightup

The goal is simple: set up the light bulbs appropriately so that every single white square gets lighted up. The light bulbs, however, cannot light up each other. Some squares have digits in them, indicating the exact number of light bulbs adjacent to that square. Use a red cross (right click) to help you identify where to not put a bulb.

It is a quick and easy game, but requires full attention because one minor mistake can cause a lot of trouble, and is typically hard to fix in larger puzzles. A little bit logic is involved, which can be improved by playing more of these.

The following is a 14-by-14 hard lightup with its final arrangement on the right.
