Don't skill shot on the first plunge—hit a yellow standup (or yellow bumper) to switch the city to Miami (NYC is a risky & low scoring mode)
If Bob's Bunker on the DMD says "Uranium ore $3 a chunk", flip both flippers twice to start Construction Mania. All targets are 3M for 20s.
The Start City Scene scoop or Blast Hole start modes. To relight start mode you need 400 miles (ramps, loops, scoops, etc.).
The "magic target" at the base of the top flipper awards free mode shots once per mode if you shoot bunker and don't flip the kickout.
Holy Grail: Light Flying Rocks -> Start Atlanta -> Magic Standup -> L Ramp -> L Shooter Lane -> 5x Blast Zone -> BZ = 200M+ & funky display
Advance bonus by hitting ramp combos (aka Bridge Out) up to 6x. One more Bridge Out shot awards one EB per game.
There is a secret skill shot if you can shoot the bunker before hitting any other switch. It's "Bob's Lotto" and worth 500K.
Hit the bulldozer to advance to Friday to light lock. Lock 2 balls in Bob's Bunker then shoot Ted for MB. Jackpots alternate between heads.
On many machines, the easiest way to get the skill shot is to bump plunge rather than plunge conventionally.
Some souvenirs + the right city = +10 mil to bonus for each. With 6X bonus, can turn into 300mil+ bonus pretty easily, so don't sell them!
