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.
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 in this routine:
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 song in the series to be covered by Dancing Bros..
The real title of the song is "Korobeiniki". It is a Russian folk song that was composed during the nineteenth century and came to be associated with the Tetris franchise due to its inclusion in the Game Boy version, where it was titled simply "A-Type".
Tetris is the second routine where one coach is carried by others during the routine after I Will Survive (On-Stage).
Tetris is one of the only routines in the main series, along with New Face, that have been added to Just Dance Unlimited, but have yet to be added to Just Dance Now.
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.
In the menu icon, it can be seen that the background is darker, and the blocks are glowing as they are falling and they seem to have less details. However, this does not happen in the actual routine.
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.
