Bonus at 20k, 30k or 40k carries over from ball to ball. Build your bonus on ball 1 to ensure bigger points on balls 2 and 3.
If you have ball cradled on L flipper, tap pass over to R flipper to then shoot spinner/drops. Big points and BIG wow factor.
Spinner builds bonus. Drop targets increases bonus multiplier. Use mini flipper to avoid a drain after hitting drops.
