Each defeated enemy gave 2 seconds on the timer, and if the player defeated several enemies without stopping, the amount of seconds given would increase more.

It was exclusively available to Nintendo Switch Online members and released on October 1, 2020.

This game, along with Super Mario 3D All-Stars and Game Watch: Super Mario Bros., was available until March 31, 2021.

The games battle royale mechanics are similar to Tetris 99, another game only available to Nintendo Switch Online members.

In the menu, the player could play a normal game or a special event, if any, along with changing their icon, which was gained by leveling up.

Leveling up was earned by obtaining experience points from playing levels.

Enemies defeated would be sent over to a different players course.

The course the enemies were sent to was determined by which course the player was currently targeting, which was surrounded by a red box.

The player could choose between four strategies to determine how they targeted other players.

On the top-left corner of the screen is the Item Roulette which costed 20 coins to use.

Using it gave the player a random item, which could be a Super Mushroom, a Fire Flower, a Super Star, or a POW Block (which defeated all enemies on the screen).

The player also had a Time Limit displayed on the top-right corner of their screen.

At the end of a game the players name, rank, number of coins collected, and the number of other players they knocked out, were displayed.

The player could also spectate the match after being defeated.

These courses were added to the pool of courses that appeared in the battle.

To unlock more courses to pick, the player would have to either complete all of the preceding levels in one of the online modes or beat the course itself when it was chosen by another player who already unlocked it or it appeared in a Special Battle.

The course order would use each players chosen course, going from whoever has the lowest level to the highest.

However, the course order will not put the same course twice in a row.

The course order looped to the first level after the last level.

Warp Zones would include the same level that the Warp Zone was located in, letting the player use Warp Zones again.

In World 1-2, the pipes of the warp zone from right to left skipped one, two, and three courses respectively.

In World 4-2, the single pipe at the end of the main area skipped one course, while the overworld Warp Zone pipes from right to left skip one, two, and three courses respectively.

Defeating enemies by bouncing on them gave 2 or 3 seconds on the timer based on the type, bouncing on Buzzy Beetles gave 4, and bouncing on Hammer Bros and Lakitus gave 5.
