Mario's Picross
马里奥：'s Picross
Mario's Picross is a puzzle game developed by Nintendo for the Game Boy in 1995. Players solve nonogram puzzles to reveal pixel-art images of Mario characters and items. The game presents a grid of empty squares with numerical clues along the top and sides. These numbers indicate how many consecutive filled squares appear in each row and column. By logical deduction, players determine which squares to fill and which to leave blank, gradually revealing hidden pictures. The game features over 200 puzzles arranged in progressive difficulty levels. Controls are simple: use the d-pad to navigate the grid and buttons to mark squares or clear them. Incorrect solutions can be verified and players can receive hints if stuck.
