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 "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.
The Start City Scene scoop or Blast Hole start modes. To relight start mode you need 400 miles (ramps, loops, scoops, etc.).
On many machines, the easiest way to get the skill shot is to bump plunge rather than plunge conventionally.
The “bridge out” combo is started by the opposite inlane switch, it is not a ramp combo as many think. Rolling through the inlane from another shot or even alley passing will also start the bridge out.
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.
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!
Plunge the Blast Hole skillshot for 5M+ points, a souvenir, and start the next city. It's safe and valuable. Also possible after ball save.
