At the beginning of the game, your primary strategy should be to target the Black Hole drop targets in sequence. This should be your main focus. The secondary objective here is to inadvertently hit the correct targets to advance the multiball. If you manage to cradle the ball on the left flipper, take the opportunity to aim for the right-side targets to progress the multiball. Once multiball is activated, shift your focus to locking balls and initiating the multiball phase. During the lower playfield multiball, prioritize advancing bonus multipliers and completing all drop targets. Having many multipliers makes it worthwhile to attempt returning to the lower playfield to accumulate more bonuses. However, if your multipliers are few, continue to play your heart out in the upper playfield.
Re-Entry is very important as it prevents your ball from draining once it sinks in the bottom playfield. There are 3 ways to accomplish Re-Entry:
If you have your re-entry gate open and the ball sinks, your ball will go back to the top playfield. When this happens try and hit the lower playfield shot again. If you do not hit any other switches the Re-Entry Gate will stay open and you have a free bottom playfield ball
There are two ways to increase the bonus multiplier. The first way is to hit all three lanes at the top. The second way is to make a specific shot in the bottom playfield.
To increase the Bottom Playfield Multiplier, spell out the Black Hole drop targets in order on the top playfield. This is generally considered to be a stroke of luck.
NOTE: The 2x multiplier for the lower playfield will carry over from ball to ball. However, if you achieve a 3x multiplier and then drain, the multiplier will reset to 1x.
A non lit Black Hole drop target is worth 1k points while a lit one is worth 5k
To lite a Black Hole drop target you just have to hit black hole in order and lite the orange arrow in front of the drop target
This is the same idea with the bottom drop targets but you want to lite the right 4 targets on the top playfield to lite these drop targets on the bottom, they are normal worth 500 points but when they are lit they are worth 3k meaning if you lite your 5x bonus and your 3x playfield multiplier each drop target becomes 45k
There is definitely a non tournament high score strategy with specials and extra balls that I am not aware of, nor do I think I will ever try and become aware of.
