Super Mario Bros. (3 Screw) is a classic side-scrolling platform game for the Nintendo Entertainment System (NES). Developed by Nintendo, the game follows the adventure of the iconic character, Mario, in his quest to save Princess Peach from the evil Bowser. Players navigate through eight different kingdoms, each filled with unique enemies, obstacles, and hidden secrets. Also, players can create power-ups by collecting special items, including the famous mushroom and fire flower. The game's distinct feature is its '3 screw' cartridge, which refers to the three screws on the back of the original NES games.
