Nintendo Kicks Off Mario Day 2026 With Classic Game Reveals and New Surprises

Nintendo has started celebrating Mario Day 2026 by announcing that a number of old games will soon be available on the Nintendo Switch Online service. The celebration, which takes place every year on March 10, has become a big deal for fans of the famous plumber. This year's party looks like it will be one of the busiest in recent memory.

The report says that on March 10, three old Mario games will be added to Nintendo Switch Online. Mario vs. Donkey Kong from the Game Boy Advance is on the list, as well as Mario Tennis and Mario Clash from the Virtual Boy, which is no longer being made. Nintendo is still working to add more old games to its subscription app, as shown by these new titles.

Nintendo started commemorating publicly in 2015 or 2016, and over time, the day became a yearly event for discounts, announcements, and homage to one of the most well-known video game characters.

Nintendo has used Mario Day in recent years to shadow-drop or pre-announce that old games will be coming to its online service. Some new features just show on the platform, while others are teased ahead of time so fans know what's coming. The three games coming out this year follow that trend while also showing off different times in Nintendo's hardware history.

Mario vs. Donkey Kong for the Game Boy Advance might be the most well-known of the new games that were revealed. The puzzle-platformer was remade in modern times for Nintendo Switch in 2024, but the original version still has some clear changes in how the puzzles are made and how the game is played. If you liked the remake, the classic version might give you a new way to look at the original challenges.

Mario Tennis and Mario Clash are the other two games. They come from Nintendo's strange Virtual Boy device. The Virtual Boy, which came out in the middle of the 1990s, used a red-and-black binocular display to try to give you a more realistic 3D experience. The system had a hard time selling and was quickly taken off the market, but it has a special place in the hearts of game historians and collectors.

Nintendo's addition of Virtual Boy games to Switch Online brings back the console's unique depth-based visual effect.

A unique 3D view can be experienced by players with a special device made just for the service. The accessory, which makes viewing feel like the Virtual Boy, lets the games show layered backgrounds and foreground features in a way that is hard for regular screens to do.

Some players like the way the graphics make the game feel more real, but some people are worried about the system's extra tech needs. Because the Virtual Boy experience depends on the device, fans have to buy extra gear on top of their Switch Online subscription. The price of the accessory can range from about $25 to $100, depending on the type. This makes it harder for players to get those games.

Even with this problem, the Virtual Boy selection is still interesting to many players who didn't get to try it when it first came out. For example, Mario Tennis on the Virtual Boy was famous for showing off the depth effect of the system while playing, with the moving tennis court and ball making it look like you were in 3D space.

Some fans think Nintendo could make Virtual Boy games more accessible by letting them run in normal handheld or docked modes without the extra.

Players have thought that other ways to watch the games might be technically possible since promotional trailers for the games can already be seen on regular screens. If there were a feature like this, it would make it harder to experience depth in some games, especially ones that rely on environments with lots of levels or things moving toward the player.

But people who like the idea say that giving people the choice would still make the games more available to more people through the subscription service. There is also hope that future updates will include ways to customize the game, such as different color schemes. The original Virtual Boy had a bright red-and-black screen that stood out, but it wasn't always easy to play on for long periods of time. Modern audiences might be more interested in the experience if there were more color choices.

Even though these arguments are going on, the Virtual Boy games give players a rare chance to go back to one of Nintendo's most experimental hardware times. This could be the first chance for many gamers who missed the system the first time around to play its unique games.

Besides the three new confirmed games, people who follow the industry think Nintendo will still make more news on Mario Day 2026.

The company has released multiple rounds of updates in the past, often mixing game additions with sales and multimedia updates. One of the most likely items to be mentioned is a deal on Mario games made by Nintendo. Nintendo typically lowers the pricing of its best-selling titles in both digital and physical storefronts to celebrate Mario Day. Stores like Best Buy, Target, and Walmart have been part of these deals in the past. They normally give away about 30% of some things for a limited period.

These sales usually don't just happen in the official Nintendo eShop; they also show up at big stores during the week before March 10. Because of this, Mario Day has become one of the best times for Nintendo fans to get more first-party games.

A new trailer for the planned Super Mario Galaxy movie could also be a big deal. Since the movie's release date is getting close, Mario Day could be a great time to show off new footage or reveal more information about the project. When it comes to Mario Day, Nintendo has sometimes used short promotional movies to show off new Mario-related projects. These videos usually last between five and ten minutes and talk about future games, teamwork, and anniversary celebrations.

It's also a big year for the brand, as Mario Day 2026 falls on. This year is the 40th anniversary of Mario's debut in video games, and Nintendo has already hinted at a number of projects that will be connected to the event. There has also been talk of the potential of a new mainline 3D Mario reveal. Big news like that would be great for the series, but many experts think Nintendo might save that for a bigger Nintendo Direct show later in the year.

Nintendo usually saves its biggest first-party news for full Direct events instead of smaller presentations with a theme.

It's possible that a new 3D Mario game would be the main attraction at one of those bigger shows. March looks like it will be a great month for Nintendo Switch Online users, even though there won't be any big new games released. In addition to the three Mario games that will be available on Mario Day, another famous game will likely be added later in the month.

It is said that Pokémon XD: Gale of Darkness will be added to the GameCube library in Nintendo Switch Online. If approved, the addition would make the service's old games even better and give players another highly-requested game. When added up, the March releases could make March one of the best months for the subscription service in recent memory. Nintendo's monthly releases of old games have been criticized for being too slow at updating, but this month's list suggests a more robust approach.

For now, the release of three old Mario games is just the start of the celebrations for Mario Day 2026. Fans may have even more reasons to party as the famous plumber's big day gets closer. Discounts, trailers, and even surprise announcements are still possible.
