Yeah, 3 three games in one day is a question of timezones. If you are near GMT you should only really get two. I got three, once I think ,but one was at 00:07 in the night so it doesn't really count.
I do get games within a few hours of eachother a lot tho, which can be a little annoying if you cant play in that time.
You need 1 of 2 things - green packs or 22 strong players to rotate in so your players don't get tired if you can't use any packs. So building a team is important, depending on the strategy you go for.
