On 3-ball: drop targets required for 5x Bonus changes with each ball. Ball 1: 10. Ball 2: Q's. Ball 3: A's + joker.
Plunge for the A or C lane - the B lane can be spotted by the inlanes while the A/C are on the outlanes.
Feeding the ball up top for EB or towards the Ace bank is generally the safest way to play. The closer targets are more risky.
