I've been wondering this for a while. My views are out of 100 people, there are times I finish 7 levels in 10 minutes and other times I'll stop and go back 12 hours later and complete it. No matter what, all other players have finished competed/completed 7 levels simultaneously. Furthermore, if the other 99 players weren't recorded, that would mean at some point I'd have to wait and see what my share of the jackpot would be.
This leaves me to believe that either the 99 other players are bots at random OR I'm playing against recordings of other players. Either way there's no way this is live AND I should know what my potential share of the jackpot is from step 1. This way I can know whether or not it's worth an extra 10 bars for a few moves if the pot is going to be large.
