players control Mario and his brother Luigi, and the goal is to defeat waves of enemies in an endless series of stages. The gameplay is simple but challenging, with a focus on strategy and timing.

Key Gameplay Features Platforming Action: The player must jump and hit the floor below enemies (often referred to as "bumping" them) to flip them over, giving the player an opportunity to kick them away for points. This mechanic is at the core of the game. When enemies are flipped in quick succession, the player earns progressively higher points, which is crucial for achieving a high score. Enemies: The enemies in Mario Bros. come from pipes, descending onto the screen and traveling downwards before they can enter the pipes again, only to reappear from the top. The types of enemies vary as the player progresses through the levels. Shellcreepers (the classic Goombas), Sidesteppers, and Fighterflies are some examples. Each type of enemy behaves differently, adding complexity as the player advances. Bonus Levels: Every few phases (such as Phases 4, 9, and every seventh phase after), a bonus stage appears where the player has to collect all the coins scattered around to earn extra points (e.g., 5,000 or 8,000 points). These stages offer a break from the regular gameplay, challenging the player to complete the task quickly, as there is usually a time limit. POW Block: The POW Block is a special item that can be used up to three times per stage. When activated, it flips all enemies on the screen, giving the player a moment to clear the area of enemies, which can be a life-saving tool when the screen becomes crowded with foes. Scoring System: Points are awarded for defeating enemies and collecting coins. The maximum score the game can display is 999,990, after which the score resets back to zero. This scoring system encourages players to aim for high scores by defeating enemies in rapid succession. Increasing Difficulty
