Goal Pole

A Flagpole appears at the end of every level in Super Mario Bros., Super Mario Bros.: The Lost Levels, New Super Mario Bros., and New Super Mario Bros. Wii. The flags on a flagpole come in many colors, though Red Flagpoles usually indicate an alternate exit in the New Super Mario Bros. games. If the player manages to grab the top of the flagpole, they will earn an extra life. In New Super Mario Bros. Wii, there are Bowser symbols shown on the flags instead of skulls. In Super Mario World, there were Giant Gates instead of flagpoles.

Mario or Luigi have to jump and grab the flagpole to end the level. In Super Mario Bros.: The Lost Levels, Luigi can easily jump over the flagpole due to his better jumping abilities. In order to still finish the level, he has to jump at it from the other side. It is unknown whether or not this is a glitch, as it does not cause any errors. It was not fixed in Super Mario All-Stars. Interestingly, in New Super Mario Bros., while being Mega Mario or Mega Luigi, they can knock over the flagpole, and then shrink into their regular form and head into the castle. By doing this, they end up earning five extra lives.

Mario could also jump on flagpoles in Dance Dance Revolution: Mario Mix, in the Flagpole Leap mini-game. This game answers the question, "Why jump on the flagpoles?". The answer is, "Why not?".

Flagpoles also appear in the Bowser inter-missions in Paper Mario: The Thousand-Year Door. In Mario & Luigi: Superstar Saga, there is a flagpole in front of the Little Fungitown that can be slid down on in the Beanbean Kingdom. A flagpole is also seen in the Super Mario Bros. picture behind the Border Bros..

In the opening cinematic of The Super Mario Bros. Super Show!, Mario, Luigi, Toad and Princess Toadstool can be seen sliding down multi-colored flagpoles.
