If you're a fan of classic brain-busters like Sudoku, then Nonogram FRVR is gonna be right up your alley. This mind-bending game will seriously test your noggin and give your brain a real workout. Each level throws you onto a grid, and on the edge of each row and column, you'll spot some numbers. These digits tell you how many squares need to be lit up. A lone number means you gotta light those squares right next to each other. So, if you see a “2,” that means you light up two squares side by side in that row or column.
