Level up

"Wahoo! One more suit, and it's 1-Up time! I mean, level-up time!"

- Mario

Level up is a term in role-playing games. Characters must defeat enough enemies in battle to gain enough experience points to level up. As characters grow to higher levels, more experience points are needed to level up. Once characters level up, their stats are increased, and in some games, they may also learn a new skill or attack.

Super Mario RPG: Legend of the Seven Stars
Upon leveling up in this game, Mario or one of his allies can chose one of three stat combinations to get a bonus on along with the regular stat boost. The three choices are attack and defense, represented by a hammer; max HP, represented by a Mushroom; and magic attack and magic defense, represented by a star. These bonuses are slightly boosted at certain levels: physical bonuses are higher on levels that are 3n (n being an integer), HP bonuses are higher on levels that are 3n + 1, and magic bonuses are higher on levels that are 3n - 1. At certain levels, the characters will learn a new special magic ability. The maximum level is 30.

Paper Mario and Paper Mario: The Thousand-Year Door
In both of these games, Mario levels up every 100 Star Points. Instead of the requirement for leveling up increasing with each level, the number of Star Points gained from enemies decreases.

At each level up, Mario must choose one of his stats to boost. If he chooses HP or FP, his maximum for that stat increase by five points. If he chooses BP, his maximum BP will increase by three points. The stats not chosen remain unchanged. Unlike most RPGs, leveling up will never directly increase Mario's attack power.

Leveling up also fully restores Mario's HP and FP and his active partner's HP in Paper Mario: The Thousand-Year Door. The maximum level Mario can reach is 27 in Paper Mario, and 99 in The Thousand-Year Door.

In Paper Mario, the music played when the player levels up is a remix from Super Mario Bros. 3's overworld theme from World 1.

Mario's partners can also be ranked up, similar to a level up, which increases their attack power and teaches them a new move, and increases their HP in Paper Mario: The Thousand-Year Door. In Paper Mario, this is done using a Super Block. These blocks are spread throughout the Mushroom Kingdom. Using one allows Mario to upgrade one of his party members to Super Rank. After he has received the Ultra Stone from Raphael the Raven, he can use Super Blocks to upgrade Super Rank partners to Ultra Rank. Each Super Block can be used only once.

In Paper Mario: The Thousand-Year Door, Merlon can level up Mario's partners, for three Shine Sprites each. One level up will upgrade a partner to Super Rank. To level up the partners again, Mario must first obtain the Up Arrow. After doing so, Merlon can level them up to the Ultra Rank.

Super Paper Mario
In this game, level up bonuses are preset, alternating between an increase of five HP at every even-numbered level and one attack point at every odd-numbered level. All party members in this game share the same stats, excluding Bowser, who shares HP but has double attack. As is the case with The Thousand-Year Door, the maximum level the party can reach is 99.

Like in previous Paper Mario games, the player's HP is fully restored with each level up.

Mario's party can also permanently increase their HP and attack power without leveling up by using the HP Plus and Power Plus items. However, both of these items are very rare.

Mario & Luigi series
In these games, max HP, max BP (Mario & Luigi: Superstar Saga, Mario & Luigi: Dream Team and Mario & Luigi: Paper Jam), max SP (Mario & Luigi: Bowser's Inside Story only), Power, Defense, Speed, and Stache (Horn for Bowser) are all initially increased immediately after leveling up, generally anywhere from zero to five points, but as high as fourteen in Partners in Time. The player can then choose any stat they want and give additional points to it.

A roulette determines how many additional points are added. The possibilities are 1 to 5 in Superstar Saga, 1 to 6 in Partners in Time, 1 to 9 in Bowser's Inside Story, and 1 to 5 in Dream Team. However, the roulette will often not include this entire range, since the numbers that appear on the roulette are reduced with each level-up a given stat is upgraded and increased with each level-up that it isn't upgraded.

The highest level in Mario & Luigi: Superstar Saga and Mario & Luigi: Bowser's Inside Story is Level 99, while the highest level in Mario & Luigi: Partners in Time, Mario & Luigi: Dream Team and Mario & Luigi: Paper Jam is Level 100.

In Mario & Luigi: Paper Jam, the player can no longer use bonus points to level up.

In Mario & Luigi: Superstar Saga and Mario & Luigi: Paper Jam, Stache will increase with most level ups. In all other games, Stache will never go up on its own; the player must use the bonus to level it up.

Itadaki Street series
The level system in the Itadaki Street series, including Itadaki Street DS and Fortune Street, is different. Instead of experience points, the player must collect all 4 Suits scattered around the board and return to the bank to level up. By using Suit Yourself cards, these reduce the amount of Suits required for a player to level up.

In Fortune Street, it is also known as a Promotion.

When a player levels up, a fanfare will play depending on which character levels up:
 * Mario character: A remix of the "Course Clear" music from New Super Mario Bros. plays.
 * Dragon Quest character: A remix of the "Gained Level" music from Dragon Warrior plays.
 * Mii character: Based upon which board is being played.

There is one exception: In the Practice Board, all characters use the Dragon Quest level up fanfare (even when Toad gets a promotion).

When a player levels up, they get money for their salary as follows:

The variables for determining the player's salary is:

Should a player's Net Worth reach the target amount after the salary gets added to the player's bank upon leveling up, that player automatically wins the board.

There is also a venture card that gives the player a sudden promotion without having to return to the bank.

Mario & Sonic at the Rio 2016 Olympic Games
The Road to Rio mode in the 3DS version of Mario & Sonic at the Rio 2016 Olympic Games features several Training Gyms where the player can train by participating at an event of the 3DS version of Mario & Sonic at the London 2012 Olympic Games. Depending on the place reached, the player gains Training Points. After enough Training Points have been obtained, the Mii levels up and gain stars that are needed to wear outfits. The maximum level is 10.
