Flat Zone X

Flat Zone X is an unlockable stage which first appears in Super Smash Bros. for Wii U, unlocked by breaking at least 100 blocks in a single game of solo Trophy Rush while playing as Mr. Game & Watch. Based upon and set inside a Game & Watch handheld, the stage combines the various games featured in the Flat Zone and Flat Zone 2 stages in Super Smash Bros. Melee and Super Smash Bros. Brawl, respectively. The unlock match for Mr. Game & Watch takes place here.

Like Flat Zone 2 in Super Smash Bros. for Nintendo 3DS, the Omega form of this stage is set on top of the gas station from the Oil Panic portion of the stage.

Flat Zone X reappears in Super Smash Bros. Ultimate. Due to the Dr. Mario music listed below now playing on Mario stages, the stage now has the fewest amount of My Music tracks with only two, being tied with Midgar, unless the player has purchased Challenger Pack 8.
