Events
Fourteen official Olympic Games events and three Duel Events are playable along normal events. In the Duel Events, special items from the Mario and Sonic universes are usable and certain actions increase Duel Points that are added to the total score of the team once a try, point, or goal is scored.

Tournaments
Tornaments, unlocked after winning in five single events, are event-specific and consist in three phases (qualifications, semifinals, finals), in each of which half of the athletes are eliminated. If the player manages to end up in 1st, 2nd or 3rd place, a gold, silver or bronze medal is earned. Furthermore, a special prize is earned if a condition related to each tournament is satisfied. Three levels of increasing difficulty exist. In each torunament, difficult to beat athletes are indicated with an exclamation mark. Finally, guests of the particular event of the tournament may appear after the qualification is passed, if the player talks to them their flag is earned, furthermore if the tournament is succesfully cleared, the guest challenges the player and, if beaten, is unlocked.

Leagues
Leagues are special tournaments that can be accessed after winning 25 tournaments using either an amiibo related to the Mario universe or a Sonic amiibo. The Mario League, accessed with a Mario-related amiibo, has the player's Mii facing opponents from Team Mario, while the Sonic League, accessed with the Sonic amiibo, has the player's Mii facing characters from Team Sonic. The reward of the Leagues is either a Mario or a Sonic Mii costume.

Heroes Showdown
A Heroes Showdown mode is featured as well. It is unlocked after getting the gold medal in all the single events or after getting more than seven bronze medals in the tournaments. In it the player joins either Team Mario or Team Sonic and participates in knockout rounds against members of the other team in events chosen randomly, until either all members of one team or one of the two captains; Mario and Sonic, are knocked out.

amiibo
The game supports amiibo functionality. A Mario-related amiibo lest the player enter the Mario League, the Sonic amiibo lets the player enter the Sonic League, while all other amiibo will give either coins or rings.

Costumes
As with the previous games, there are a variety of collectable costumes for the player to use for their Mii character. A majority of the costumes return from the previous installments, in addition to some brand new ones.

Music
As in the previous installments, music can be collected. All guests' themes are unlocked after beating them in an event.

Stamps
Players are able to obtain stamps to use in Miiverse posts. There are a total of 100 stamps in the game. Stamps are obtained at the item stands.

Pre-release and unused content
The game originally featured Boom Boom among the playable characters of Team Mario in the introductory video of the game shown in the Nintendo Direct of March 2016. This video was also reused as the introduction of the game. Despite this, in the final game Dry Bowser, who doesn't appear in the introduction among the playable characters of Team Mario and is only referred to through his flags, replaces Boom Boom and the only playable Boom Booms are the supporting characters of the Rugby Sevens events.

Trivia

 * This is the first Mario and Sonic game to feature new playable characters since the second game.
 * This is the first home console Mario & Sonic game to be released on the same year of the Olympics in real life, being released six weeks before the Opening Ceremonies begin in real life.
 * Like in Mario & Sonic at the Sochi 2014 Olympic Winter Games, there are special animations for some paired characters for whenever the player gets first place in a team event, all being recycled from that game (with some new ones added for characters like Mario and Toad, Sonic and Jet, and Donkey Kong and Diddy Kong).
