The gameplay is generally the same as past entries with Simple rules stripping the extraneous rules. Matches are available up to 4 players and the game supports motion controls with a single joy-con. The game also has a story mode with many varied moves.
The main new mechanic is the energy meter. Players can use their generated energy meter to perform Zone Shots which are powerful shots the player can aim using motion controls. If the player hits the opposing player's racket straight on, it gets damaged and if it gets damaged 3 times, it will break and that player must forfeit the match. To counter this, the opposing player can use Zone Speed using up their own energy meter to slow down everything to hit the ball. if a player fills up their entire energy meter, they can spend it all to perform a special shot that can destroy the opposing player's racket in a single shot. The only way to avoid breaking the rackets is to use the Block move which is a perfectly timed swing that reflects the shot to the other side with no damage. To fill up the energy meter, the player can perform risky Tricky Shots though it will generate with long rallies.
In this story mode, the player moves on a map and must face various challenges on their journey in a stage based format a la New Super Mario Bros.. Luigi has awakened evil Tennis deity called Lucien and it corrupts him and the evil characters. Mario must save Luigi with tennis against various bosses. After defeating each main boss, he collects a Power Stone. Mario can also collect different rackets over the course of the journey with different attributes and improve his stats. If all the rackets break, the player receives a game over.
