I didn't see any post about ?-8, probably because it's pretty simple but I'll post my strategy anyway. To get three stars I took one squad from the top and placed it at the bottom with the squad at top being noticeably faster, by about 120 than the others which are roughly the same speed. After RNGesus gives you his blessing, the best way to get the most tickets is by taking the left most squad and placing it at the starting tent node right before the random node, maximizing the chances of getting all the tickets, at 43 tickets total, with the rest of the setup being the same.
