Gameplay
Super Mario Bros. 35 is a battle royale where 35 players compete against each other until only a single player is left. In the menu, the player can play a normal game or a special event, if any, along with changing their icon, which is gained by leveling up. Leveling up is earned by obtaining experience points from playing levels.

During a game, players go through levels from Super Mario Bros. Enemies defeated will be sent over to a different player's course. The player can see other players' games. The course the enemies are sent to is determined by which course the player is currently targeting, which is surrounded by a red box. The player can choose between four strategies to determine how they target other players. Other player's enemies can also be sent to the player. On the top-left corner of the screen is the Item Roulette which costs 20 coins to use. Using it gives the player a random item, which can be a Super Mushroom, a Fire Flower, a Super Star, or a POW Block (which defeats all enemies on the screen). The player also has a Time Limit displayed on the top-right corner of their screen. Defeating enemies gives the player more time. If the player is the last player alive, they win the game. At the end of a game the player's name, rank, number of coins collected, and the number of other players they knocked out, is displayed. The player can also spectate the match after being defeated.

In a regular 35-Player Battle, the player can pick a course and pay coins to start the game with a power-up. These courses are added to the pool of courses that appear in the battle. To unlock more courses to pick, the player must complete the previous level in one of the online modes.

In Special Battle, limited-time events are held where players play through a set order of courses with special conditions, such as starting with 100 coins. The battle can start in any course, and will go through the courses in order then loop to the first level after the last level.

Coin Ranking
In Coin Ranking, players are ranked by their final total of coins at the end of the game. Players receive a grade based on their rank, with S grade at the top and A through E following it. The top 100 players of the week are listed with their coin score on online leaderboards. The players coin score is the sum of the coins collected during the game, coins collected from the chest, and a rank bonus. That sum is doubled by the Small Mario Bonus if the player starts without an item.

Daily Challenges
Each day, the player gets three random challenges to complete for up to a total of 600 coins. The total list of challenges is below:
 * Defeat 20 enemies in 35-Player Battle.
 * Use Item Roulette once in 35-Player Battle.
 * Clear 30 courses in 35-Player Battle.
 * Target and send enemies to "Attackers" 10 times in 35-Player Battle.

Glitches

 * The glitch to jump in midair from Super Mario Bros. is retained, but not with items from the Item Roulette. When the player obtains a Super Mushroom or Fire Flower in midair and presses while Mario is transforming, he will jump in midair.
 * If the player presses and  during the same frame, they will be able to advance to the next stage without unlocking it yet. If that stage is cleared, the player unlocks it.
 * Touching a Super Mushroom and an enemy at the same time causes Mario's lower half to briefly enter the ground before reverting to Small Mario.
 * Dying as Small Mario and getting a Super Mushroom in the Item Roulette at the same time makes Mario's sprite grow to Super Mario, then move up and down like the death animation.
