Easy

Hit the post between the u-turn and the right ramp. This qualifies a lock, then lock a ball in the u-turn. After 2 locks you get a multiball at the scoop.

Medium

Setup a multiball and an adventure together. Multiball is pretty easy and safe, adventures are not worth much until you get far - so I pretty much try to play every adventure with a multiball stack.

When in multiball use first few seconds to hit meeseeks for playfield multiplier. Multiball + mode + 4x scoring beats almost everyone.

Hard

General notes

Skill shot - Its lit on the playfield. I like doing the upper loop (spinner), because if you combo it - it increases the skill shot value.

Note - portal will light megaseeds which is high bonus.
