Qualify MBs and stack them before starting them all at once to boost Jackpot value. MBs can be started during other MBs as well.
The skill shot is to hold the left flipper and then shoot the right ramp (5M) on the fly. This can be draingerous, so best to try to live catch the ball as it makes the flipper and play with control. Not holding in the left flipper sends the ball to the pops where it can also become draingerous.
Multiballs
There are 5 MBs in the game (all 4-ball MB), you can, and should, qualify multiple MBs and start all at once at the New York lane (between the left orbit and Godzilla's enormous head)
MBs can be started during other MBs by completing the MB qualifying steps (you do not need to shoot the New York lane again)
The more MBs stack when you start them the higher the Jackpot value:
single MB: 5M, 2 MBs: 7M, 3 MBs: 10M, 4 MBs: 17M, 5 MBs: 25M
Bringing in another MB during a MB adds to the Jackpot value as follows:
starting a 2nd: +1M, 3rd: 2M, 4th: 3M, 5th: 4M
