Dance Dance Darkmoon

I have made a weak aura helper that makes it easier to do this, especialy if you are planing to fast spam it just for achievement.

While the oponent is performing his dance moves, click the icons you see on the center of the screen.
When its your turn to perform. spam the center button that appears and that will execute the sequence you inputed.

edit:
Weak aura updated for Dragonflight ui changes.

I took the quest, but the guy doesn't show me any options to start the game.

EDIT: Turned out, I was stuck in the Racing game, and I had to leave the zone and come back to be able to lose the toll debuff and have the option to play anything else.

This Darkmoon Faire game is a fairly standard 'Simon Says' game where you are asked to repeat the pattern performed by the NPC. On easy difficulty there are three steps, on medium there are four steps, and on hard there are five steps. The number of steps remains the same throughout the dance on each difficulty. Unless you do the hard dance perfectly on the first try, you will be required to complete the dance multiple times in order to satisfy the quest requirements. As a result, this daily quest will take longer than most of the other dailies.

An 'Accolades' bar will fill up depending on your dance performance, and the percentage for each performance is calculated based on your performance and difficulty. There are three levels of difficulty, easy, medium, and hard, and a 'fail', 'pass', and 'perfect' condition within each difficulty that each award a different number of accolades. The exact percentages are listed below:

Hard (perfect score): 100%
Hard (pass): 50%
Medium (perfect score): 33%
Medium (pass): 25%
Easy (perfect score): 20%
Easy (pass): 17%
Fail (any difficulty): 10%

While it is quickest to simply complete a perfect run of the hard level for your daily quest, there are a number of achievements to be earnt that will require you to complete the dance multiple times on all difficulties:
