Gamer

Gamer is 9-Volt and 18-Volt's minigame in Game & Wario, for Wii U. The game is played using the 's buttons. A stage based on the minigame makes an appearance in Super Smash Bros. for Wii U and Super Smash Bros. Ultimate, also called Gamer. 5-Volt makes an appearance as a stage hazard.

Gamer returns in WarioWare Gold as a stage in Challenge Mode, this time under the name Sneaky Gamer. The microgame Mole also reappears in the game.

Story
Playing with their new console, 9-Volt and 18-Volt compete to find out who gets the high score in the game and 9-Volt wins. During their celebration, 5-Volt takes the console from them and orders them to do their homework. After some time, 9-Volt and 18-Volt are done and get eager to play again. 5-Volt gives the console back, revealing she had beaten her son's score by a wide margin, making him shocked.

Gameplay
There are two modes in the minigame. Both involve the characters playing a modified version of Balloon Fight containing microgames, called Balloon Fighter.

9-Volt
In this mode, the player must help 9-Volt to win microgames and avoid letting 5-Volt know that he is playing during his bedtime. She will constantly look into his bedroom through his door to see if he is sleeping, forcing the player to hide and pause the game. The Wakey Meter displays the amount of time 9-Volt can stay awake. The game ends if the player fails to hide their game from 5-Volt, if the Wakey Meter runs out, or if they lose all chance balloons. 5-Volt also may look through the window, or pop out from the TV. If the player receives at least 1000 points in level 1, 2, or 3, they will achieve Gamer status. If they score at least 30 points in the Endless level, they will also achieve Gamer status. Achieving Gamer status rewards a coin for the Cluck-A-Pop.

Levels

 * Level 1: There are no distractions except a cat that will open the door instead of 5-Volt.
 * Level 2: There are a few more distractions such as an old man with a wig that will walk by 9-Volt's window. The television will also turn on to two different programs, and then change to a one more channel where 5-Volt comes out to try and catch 9-Volt. 5-Volt may also run to 9-Volt's window and break it open. In Sneaky Gamer, 5-Volt might break the window open and immediately look through instead of opening it, giving the player less time to hide.
 * Level 3: In this level, it contains all the distractions that were in Level 2, along with a few additional scenarios to look out for. First, when the old man walks by 9-Volt's window, he may meet 5-Volt who will walk to 9-Volt's window and open it. 5-Volt may also stay in 9-Volt's room and watch television shows briefly, looking back at 9-Volt a few times or rush over to his bed to attempt catching him in the act. In Sneaky Gamer, 5-Volt can appear by lifting up the TV and look through which is indicated by the entire set shaking.
 * Endless: This level is at the same difficulty as Level 3 except now it will continue until the player loses all of their chance balloons, 5-Volt sees 9-Volt, or 9-Volt falls asleep. A Cluck-A-Pop coin may drop onto the console and appear in a microgame. Tapping it will claim them.

18-Volt
In this mode, 18-Volt is playing the console. This mode is very similar to WarioWare games, without specific time and with three difficulty levels for microgames, only ending when the player loses all four chance balloons.

Levels

 * Normal: If the player scores 40 points or more, they will achieve Gamer status.
 * Ultra Speed: From the beginning, the games go very fast. If the player scores 20 points or more, they will achieve Gamer status.
 * Hardcore: At the start, the player begins with one chance balloon left and all microgames are set to their hardest difficulty. If the player scores 10 points or more, they will achieve Gamer status.

Description
"I'm 9-Volt! Can you play video games AND avoid my mom's evil stare? I made this game to show everyone how annoying she is!"

''Hi, I'm 9-Volt! I just got the new super-popular portable game BALLOON FIGHTER! I'm kinda bummed right now because my mom beat my high score, so I'm staying up past my bedtime to get it back! She keeps coming by to check on me, though, so I have to pretend to be asleep...which is actually making me kinda sleepy.''
