I think the 100 point gem event is bugged. Presumably the intent is for it to require 100 points total from the entire gem round (as opposed to 100 from a single click of it which there simply isn't enough time for), but it will not complete even when the value of the last click reaches 14 (as 1+2+3+4+5+6+7+8+9+10+11+12+13+14 = 105), and I have not satisfied the objective even reaching 17 or 18.
