The kickback feature in a pinball machine allows the player to continue where they would have otherwise drained out the left outlane. A solenoid fires (not unlike an auto-plunger) against the ball, which quickly shoots it up the outlane and back into the playfield. For many games, this is enabled as part of the ball save and given to the player as a reward during normal play.
Hardware
The only unique part of this feature is the solenoid that's mounted in the apron area. A lane guide will need to be mounted for the ball to properly shoot upward and towards the left.
Normally there is a playfield lamp in the outlane to indicate to the player kickback is active.
Resources
- A sound or call-out indicating to the player that kickback is enabled.
- A sound or call-out when kickback is invoked.
The action of the kickback is simply pulsing the solenoid. What is critical is getting the timing correct where it doesn't fire too soon or too late where the ball will be missed. Some timing adjustments will need to be done to find the sweet spot where it will handle the most amount of ball velocity variations.
Programming
Some checks will need to be done to ensure that the ball is out of the outlane area. One solution is to leave it active for a specified period of time to give an additional kickback to ensure the ball is out.
