All 8 games will be played but the Freebitco.in website has not chosen all of them to be available for betting.I think it is in their sole discretion what events they bring up for betting in the platform and mostly they have done so because we are just a couple of days before the Lambo draw and most people are not at all concerned about betting on Football rather they are wagering a lot in order to collect as many GT tickets as possible.
For betting you may get GT as well, no?
BTW it would be interesting to check if what you said is true - if there is an increased "generation" of GT in the last weeks/days. Maybe what we may do, is to record the total number of tickets every week and then see if indeed at the end people wager/buy/receive more tickets than earlier.
