Especially for players who are going for world-record Duo runs:
Clear 10 lines in a row without repeating pieces(e.g. Quad with I, double with L, single with Z, single with T, double with O = 10)Place 10 pieces without using soft/hard dropPerform a 20+ spikeClear 20 lines in a row on only one column of the boardPerform a 3 B2B combo(e.g. L-spin, two TSDs with fractal, and Quad combo)Perform the type of clear (with the exact piece) your partner used before topping out(if the partner didn't clear anything, this task will not appear)Trigger a speed level decrease twice(e.g. if you are speed level 9, get down to speed level 8; you don't exactly need to go down 2 levels)Perform a Quad Color ClearPerform a T-Spin Mini Double(which is only possible with Polymer spins)Send the first three digits of your altitude in chat(e.g. if your altitude is 3,125.6m, type "312" in chat)



which.........actually yeah they try their very hardest not to hit F10
