Super Mario Bros. 35

Super Mario Bros. 35 was a 2D platformer and battle royale game for the Nintendo Switch created to celebrate the Super Mario Bros. series' 35th anniversary. 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 game's battle royale mechanics are similar to , another game only available to Nintendo Switch Online members.

Playing a round before March 31, 2021 was one of the 35th Anniversary site My Nintendo missions to be completed, though it did not actually register until a week after playing at the latest.

Gameplay
Super Mario Bros. 35 was a battle royale where 35 players competed against each other until only a single player was left. 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.

During a game, players went through levels from Super Mario Bros. Enemies defeated would be sent over to a different player's course. The player could see other players' games. 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. Other player's enemies could also be sent to the player. 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. Defeating enemies gave the player more time, up to a maximum of 400 seconds. If the player was the last alive, they would 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, were displayed. The player could also spectate the match after being defeated.

Courses
In a regular 35-Player Battle, the player could pick a course and pay coins to start the game with a power-up. 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. This was the only way a course can repeat.

Warp Zones let the player skip forward in the level queue. 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.

In Special Battle, limited-time events were held where players played through a set order of courses with special conditions, such as starting with 100 coins. The battle could start in any course.

Playable characters

 * Mario
 * Luigi - Luigi was playable by holding while selecting a course or selecting Special Battle. Luigi was only playable after every course was cleared at least once.

Cameos

 * Princess Peach - Only appeared as an icon
 * Toads - Only appeared as an icon

Enemies
The enemies were the same as in Super Mario Bros. (except fake Bowsers did not appear) and mostly retained their behavior. Every defeated enemy was transferred to the targeted player's enemy queue. This queue was visible at the bottom of the screen. Enemies only appeared in the game world as the player moves forward to scrolled them into view. An enemy sent by another player appeared with a white tinted sprite; however, it behaved exactly like a natural enemy, including the ability to send it to other players. When a player entered a bonus area, the enemy queue was instantly cleared, and any enemies sent while in the bonus area are removed as well.

Enemies that had multiple identical-looking variants (e.g. Green Koopa Paratroopa and Bowser) would have the correct variant appear for the target player. Enemies of the same kind with different behavior would retain their behavior, like Bowsers that throw hammers, for example. Enemies that can be bounced on and then further interacted with (all the shelled enemies) would be transferred and award time on the first bounce, any further interaction with that same enemy would not cause them to be transferred again or award more time, thus also avoiding the "infinite 1-Ups trick" (which in this game would translate into an infinite time trick).

The following could not be defeated:

Changes from Super Mario Bros.
Super Mario Bros. 35 was based on the NTSC version of Super Mario Bros. Generally, many physics and other mechanics had been altered to fall more in line with newer Mario games, similarly to Super Mario Maker; some examples as follows:
 * If Fire Mario took damage, he reverts to Super Mario instead of Small Mario, as in the international NES and Super Mario All-Stars versions of Super Mario Bros. 3, as well as Super Mario World: Super Mario Advance 2 onward.
 * Similarly, if a Fire Flower was grabbed as Small Mario, he would go straight to Fire Mario, as in Super Mario World and later games, instead of only growing to Super Mario like in the original. If the powerup had no effect due to Mario already being in the resulting state or higher, it awarded 15 seconds on the timer instead.
 * Since lives were no longer present, 1-Up Mushrooms now awarded 20 coins. The coin counter extended to at least four digits.
 * 1-Up Mushrooms needed conditions to appear were now always available.
 * Bouncing off an enemy while holding the jump button would cause Mario to bounce very high, like in Super Mario Bros.: The Lost Levels and later games.
 * Similarly, the "Super Jump" introduced in Super Mario Bros.: The Lost Levels had been added. Stomping the top of an enemy while moving upwards at the right trajectory would cause Mario to soar very high.
 * Sometimes when super jumping off of a Koopa Troopa or Koopa Paratroopa, they would instantly enter their shell and got kicked sideways.
 * Enemies now interacted with trampolines, similarly to Super Mario Maker. This was most visible at the end of World 2-1, where enemies might drop from the tall wall of solid blocks and fall on the trampoline. Mario's general physics while interacting with a trampoline were much smoother, akin to other recent platformers.
 * Stompable enemies that are transferred to underwater levels are now stompable underwater, like in Super Mario Advance 4: Super Mario Bros. 3.
 * The mechanic that pushed Mario out of a solid block had been removed; instead, they acted like in Super Mario Bros. 3 onward: If Super/Fire Mario stopped in a 1-tall space (or powers up from Small Mario while in one), he would continue to crouch. If the blocks above were Brick Blocks, he could jump and break them, but even if they are solid blocks, he could make small hops to eventually escape.
 * The level-ending transitions were shortened. The player moved to the next course after Mario reached the flagpole or after the bridge collapsed from picking up the axe. The cutscenes with Toads and Princess Peach no longer appeared, although they made cameos in the game's icons.
 * However, bridges now collapsed in castles when Bowser was defeated before touching the axe.
 * The block portion of Fire Bars no longer damaged Mario, but instead acted as if he hit a solid block.
 * Mario had a proper animation for entering the pipe at the end of an underwater level, instead of simply vanishing as he did in the original game.
 * When going down a pipe, Mario always crouched, it is no longer possible to "walk" or "slide" down into a pipe.
 * If Mario passed a Hammer Bro. without defeating it, it would begin to chase after him. Hammer Bros. jumped more often.
 * Almost every glitch from Super Mario Bros. has been fixed. This includes Minus World, Over the Flagpole (there was an invisible wall above the flagpole), Die and Complete Simultaneously, Disappearing Power-Ups (multiple power-ups appeared on screen), Harmless Enemy (Mario would take damage while inside enemies after post-damage invincibility), Hit the Axe and Keep It There, Invisible Piranha Plant (the Piranha Plant has been removed entirely), Stuck Underwater (Mario's hitbox no longer shrinks after crouching underwater, and even if he powered up via the Item Roulette in the 1-block high space he could escape by hopping), Walking Through Walls, Wall Jump, and Wrong Warp. However, a few of them had been retained, as detailed in the Glitches section.
 * Bowser's flame hitbox had been increased from just covering the front tip to covering its entire length.
 * Enemies no longer turned around off of the defeated bodies of other enemies.
 * The fake Bowsers were all replaced by the real Bowser.
 * Due to the Nintendo Switch's more powerful hardware, enemies would not despawn if there are too many.
 * In World 8-4, the Piranha Plant in the pipe that took Mario to the second room would not despawn when Mario reached it, like in Super Mario All-Stars.
 * Like in Super Mario All-Stars and Super Mario Bros. Deluxe, an error buzzer sound would play if Mario goes the wrong way in a castle maze.
 * Climbing up vines was fully manual instead of automatic past a certain point up the vine, which let players use the vine longer.
 * Getting carried off the top of the screen by a moving platform would make Mario drop down instead of dying, like in Super Mario All-Stars.
 * With enough forward momentum, Mario would enter sideways pipes regardless of whether the player held forward or not.
 * Mario couldn't defeat enemies by stomping low on their body while moving downwards.
 * The Goomba that started above the second Coin Block in World 1-2 started on the ground.
 * Koopa Troopa shells could break Brick Blocks and triggered blocks containing items.
 * Fire Bars would not despawn once they are at the left edge of the screen.
 * Mario's top running speed was slightly slower.
 * In World 4-1's coin room, which reappeared as the second coin room in World 6-2, a Brick Block containing a power-up was one block above the exit pipe. Super Mario and Fire Mario were no longer able to reach the spot under it by crouching and sliding off the row of Brick Blocks to the left of it as a result of their slower speed.
 * After exiting the bonus area in World 1-1, the two Goombas did not appear.
 * After exiting the bonus area in World 5-1, the first Koopa Paratroopa did not appear.
 * Fireballs bounced lower to the ground, allowing them to hit enemies on the ground easier.
 * Mario could use fireballs at the top of the screen.
 * Lakitus did not stop following Mario, making it possible for multiple Lakitus to pursue Mario.
 * Mario could crouch if down was pressed at the same time or after a side direction was pressed.
 * Mario would stand up if left or right is pressed while crouching.
 * Super Stars would pop out of blocks instead of dropping down.
 * Mario could collect coins from the side when a block was above it, e.g. walking into the block above the coins in World 2-4.
 * Mario did not accelerate faster when moving backwards.
 * Bulllet Bills fired at a slower rate on World 5-3 and World 6-3.
 * Mario couldn't flip to the opposite side when grabbing vines.

Coin Ranking
Coin Ranking was unlocked by winning one battle. Coin Ranking was a competition each week where players were ranked by their highest number of coins in a battle in both 35-Player Battle and Special Battle. Players would be required to win one battle again to be ranked each week in each mode. Players received 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 were listed with their coin scores on online leaderboards. The leaderboards and Results Graph were only shown for the ten most recent weeks. The players' coin score was the sum of the coins collected during the game, coins collected from the chest, and a Rank Bonus. That sum was doubled by the Small Mario Bonus if the player started without an item. Special Battle had no Small Mario Bonus.

Super Mario Bros. 35 World Count Challenge
Super Mario Bros. 35 World Count Challenge was an event that was announced on January 12, 2021 along with new details about Super Mario 3D World + Bowser's Fury.

Icons
Icons of various Super Mario Bros. characters and objects could be unlocked by leveling up, with 64 icons in total. Players started with standing Small Mario, a Brick Block, a Super Mushroom, and a Goomba as their only icons. The order that the icons are unlocked were random; however, players unlocked the last icon at level Level 50★.

Special Battle events
The first name is from Nintendo of America's Twitter account, the second is from the UK Super Mario Twitter account if theirs is different, and the (second or) third is from the Japanese Super Mario Bros. 35th Anniversary Twitter account.

Reception
Super Mario Bros. 35 received mostly positive reviews.

Glitches

 * The glitch to jump in midair from Super Mario Bros. is retained. When the player obtains a Super Mushroom or Fire Flower in midair and presses while Mario is transforming, he will jump in midair. This works with the Super Mushroom and Fire Flower from the Item Roulette.
 * Like Super Mario Bros., jumping into the bottom corner of a ? Block with a power-up on top of it in a specific way causes Mario to get powered up from underneath the block. However, it is much rarer in Super Mario Bros. 35.
 * Power-ups can be obtained from the side of the block if the screen is scrolled so there is gap less than one block to the left of the block, then Mario jumps into the gap.
 * Touching a Super Mushroom and an enemy at the same time causes Mario's lower half to briefly clip into the ground before reverting to Small Mario.
 * Taking damage as Super Mario then shortly after powering up back to Super Mario will make Mario flash between Small Mario and Super Mario, which can make him fall through thin bridges.
 * If Small Mario touches a Super Mushroom while getting a Fire Flower in the Item Roulette, he will be briefly look like Small Mario with Fire Mario's color palette and his lower half will briefly clip into the ground.
 * 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. Small Mario can also die while being Invincible Mario from the Item Roulette if hit at the same time.
 * Before it was fixed in version 1.0.2, if the player pressed a direction and during the same frame, they would be able to advance to a stage adjacent to an unlocked level without unlocking it yet. If that stage was cleared, the player would unlock it.
