How in the world do you ever collect enough money to fully upgrade stadium?
Stadium
Be very active
With a maxed Ticket Office, stadium at 140k, you make 3.5 mil/game. Each day you can have a minimum of 3.5 games (1 champ, 1 tourney, and 1.5 GC games; 3 every 2 days). That is 12.25 daily (or 24.5 every 2 days). Having 10 each maxed snacks/casinos can make you another 15+/day. Making over 27 mil/day you could do it in under 3 days. Even if your snacks/casinos are level 15 that is just under 10 and you could still do it in about 4 days.
