One first I noticed missing - First licensed theme - I beleive its Bally wizard!
Quoted from soren:Games (even 1. gen SS and EM) will generally hand you the ball if it goes from plunge directly to drain without hitting any switches. I think this is because the software is not going into ball on playfield state, and hence not progressing into the game.
This may be more by accident than design. Many early games - and particularly those without accumulated bonus - would simply re-eject the ball if there were no other switch triggered. The game essentially saw it as a bad eject, and would re-eject the ball. For games with a bonus accumulation, it generally was a matter of if the game provided a bonus with the ball in the shooter lane. If so, a trip over the pf without hitting a switch would net you the single bonus. Without the staring bonus, it was essentially a re-eject.
Interestingly, i have two wizard in the workshop. While both are old but working, they both have slightly different play. In this case, one of them starts with a single bonus while the other doesn't. They also differ slightly in the flag handling - one resets flags/bonus when going thru the lane while the other doesn't. The latter allows for accumulating more bonus as the player doesn't need to hit all the targets again to set the flags. i can't find anywhere where these are supposed to be adjustable behavior.
