The routine features two men (P1 and P3) and two women (P2 and P4). The dancers are wearing helmets, and lycra suits of different colors with a Tetris piece represented on it. P1 is purple and bears a "T" shaped brick. P2 is red and bears a "Z" shaped one. P3 is light blue and bears a straight bar. P4 is orange-yellow and bears a reversed "L" bar. At one point, their skin will turn black similar to the dancers of She Wolf and Where Have You Been.
The background shows a giant 'TETRIS' sign at the beginning from which the dancers emerge. Then the background has falling Tetris pieces, like the original Tetris game. At several points, the background darkens and goes through a "Level up" phase. Near the end of the routine, the background will flash orange as the song speeds up.
There is 1 Gold Move for each player:
Gold Move: Pose according to the pictograms. This is the final move for the song.
P1: Put your left hand up and bend your right arm.
P2: Put your both hands halfway in the air and squat down.
P3: Look to the left and put your right hand to the left and the left hand up.
P4: Continue standing while turning your palms outward.
Gold Move in-game
Tetris is the third cover in the series to be performed by Dancing Bros..
Tetris is one of only four instrumental songs to be covered.
The Gold Move awards the player about 770 points if done correctly, which is more than the average Gold Move awards.
Due to the song being short, the score bar moves faster than the player's score.
A mock-up gameplay screenshot shows all four players being scored during the sequence where P4 is carried by the others. However, in actual gameplay, only P4’s arm movements are counted on remote consoles, and no moves are counted at all during this sequence on camera consoles.
Tetris is the second routine where one coach is carried by others during the routine after I Will Survive (On-Stage).
