I found this new puzzle game that I'm rather addicted to called Armor Picross. It's a nonogram puzzle (sometimes called a griddler), which is a picture logic puzzle where you fill in squares in a grid according to numbers given at the ends of the rows and columns to reveal a hidden picture. And in case I didn't explain that very well, here's a screenshot from the instructions:
The website has plenty of different puzzles to choose from, ranging in difficulty from easy (5x5 or 10x10 grids) to extreme (25x25). If you want a little extra guidance on how to solve these puzzles, there's a helpful website called Nonogram Solver that you can check out. Have fun. And don't blame me if you get addicted, too!
