Cosmic Carnival is very bonus heavy. Focus on getting bonus multipliers on the initial plunge.
Modes generally start by hitting 3 of the same shot or 3 sets of targets. All modes can be stacked with one another.
The left ramp starts Ring Leader mode. The right ramp starts Cosmic Clown mode. Ramps can be repeatedly shot as Combos.
Dropping one or two of the right drop targets opens a tunnel for the ball to return to the plunger lane, which allows getting more toplanes.
Hitting a shot will light others with orange lights for a few seconds to score Combos. Combos build base bonus.
All bonus (base bonus and bonus multipliers) carries over from ball to ball.
The center scoop scores random mystery awards. Hitting it three times with less than 10 seconds between each starts Mystic Martians mode.
On ball 3, if a multiball hasn't been started yet, the scoop will be lit for locks to start multiball, as long as no mode is running.
In Multiball, ramps (and depending on code version, Inner Loops) score jackpots for 1,000,000.
