+1 just another annoying masterpiece, even better then dragonspiral tower in xmas event. You have to be almost perfect to completed it and may have to face server lags/ network lagging and bugs like the one in rapid spin with the rounds he already complained. There are a lot of games with that type of mini games and in my opinion in PRO players have to grinding enough in different ways and you dont have to frustrate people more with such quests or at least dont make it that hard, in case players could face above mentioned problems.
