(It resembles Lights Out. If you don't know Lights Out, look for an electronic version on Ebay from Tiger Electronics. They produced 3 versions of it - really terrific.)
The object is to match the image in the top left corner. Tap on a white cell and it turns to 1. It will not affect its neighboring cells if they are white. However, if the neighboring cells (horizontal & vertical) are not white, they will increase by 1.
Each cell must be tapped once and only once. If a cell reaches 4 and gets increased again by its neighbor, it will go back to 1.
There are 64 levels. Right now I've done 1-48. But I skipped 41. I mostly do LogiSquares when I wake up and can't go back to sleep. After 45 minutes on LogiSquares, I'm good.
LogiSquares is a very good thinking puzzle with a good number of easy levels to jump right in. I think I'd like to see a pentagonal version of this.
Great job Parker!
