Lock two balls into the Jailhouse and Rock will start with a three ball multiball...

When playing with more than one pinball, things tend to get a little stressful. These are some of the skills you can use to make multiball a little more manageable:

Detaining

Send balls around long time consuming ramps such or into jet bumpers, so that the ball is out of the way for the time being and you can pay attention to the others.

Deliberate Drain

Most modern multiballs now start with a ball saver, so take advantage of that by just keeping one or two in play and collecting unobstructed jackpots while the trough and the auto kicker take a few seconds to send the balls back onto the playfield.

Trap and Play

Trap a ball with the flipper which is not required for the next Jackpot and attempt to score the Jackpot while holding the trap. This is a good way of getting shots at the Jackpot while unobstructed by the other balls.

Billiard Block

Another advantage of the trap and play is the ability to perform a Billiard Block. If you see that the free ball is heading to leave the playfield, use the trapped ball to knock it out of the way, preferably hitting it on either side, so that neither one of the balls go down the middle.

Escaping a Multitrap

If you have two or more balls trapped on the same flipper, and you need to only free one, you should attempt to escape the Multitrap by hitting the trapping flipper very quickly. This will hopefully cause the outermost ball (the one closest to the tip of the flipper) to do a little slingshot pass while the other balls remain trapped at the base of the flipper.

Of course you need to practise these tricks, But hey, isn't that what it is all about?
