Abstract

A method of determining duration of a play session is described herein using a ball saver. An elapsed game time is tracked and a current round of play identified. Using the current round of play and the elapsed game time, a save time is determined. Finally, an autosave for a duration equal to the save time is activated using mechanical stop, flippers, or programmatic solutions.

Claims (35)

1. A method of determining duration of a play session on a pinball machine comprising:

initiating a play session on the pinball machine, the play session divided into a plurality of rounds and occurring on a playfield of the pinball machine;

tracking an elapsed game time for the play session;

identifying a current round of play as a first, intermediate, or final round of play,

determining a save time based on the current round of play and the elapsed game time; and

activating an autosave for a duration equal to the save time at the initiation of the current round of play, wherein for the duration equal to the save time the autosave prevents an ending of the current round of play,

wherein determining the save time for an intermediate round or a final round is proportional to the ratio of the difference between an ideal game time and the elapsed game time;

a mechanical stop configured to be moved into the playfield to block a ball from entering a drain.

2. The method of determining duration of a play session of claim 1 wherein a default amount of save time used when the elapsed game time is minimal.

3. The method of determining duration of a play session of claim 1 wherein the portion of the ratio of the difference between the ideal game time and the elapsed game time is a scaled factor relating to the current round of play.

4. The method of determining duration of a play session of claim 1 wherein the portion of the ratio of the difference between the ideal game time and the elapsed game time is 25% for the intermediate turn.

5. The method of determining duration of a play session of claim 1 wherein the portion of the ratio of the difference between the ideal game time and the elapsed game time is 50% for the final turn.

6. The method of determining duration of a play session of claim 1 wherein the autosave further comprises a flipper automatically configured to be engaged in the playfield to block a ball from entering a drain.

7. The method of determining duration of a play session of claim 1 wherein activating the autosave further comprises relaunching a ball without incrementing or ending the current round of play.

8. A method of managing a play session on a pinball machine comprising:

determining an ideal game time of the play session occurring on a playfield of the pinball machine prior to an initiation of play, wherein the play session is divided into a plurality of rounds;

initiating a game timer to track an elapsed game time for the play session;

launching a first ball to begin an initial round;

Notice of Non-Compliant Amendment activating an autosave for an initial amount of time, wherein for the duration equal to the initial amount of time the autosave prevents an ending of the initial turn,

monitoring the user's play for a concluding signal,

completing the initial round in response to the concluding signal;

launching a subsequent ball to begin a subsequent round;

activating the autosave for a second amount of time determined by the elapsed game time, wherein for the duration equal to the second amount of time the autosave prevents an ending of the subsequent round;

completing the subsequent round in response to the concluding signal;

launching a final ball to begin a final round in response to the concluding signal;

activating the autosave for a final amount of time determined by the elapsed game time, wherein for the duration equal to the final amount of time the autosave prevents an ending of the final round, and

completing the final round in response to the concluding signal;

wherein determining the initial, second, or final amount of time for an intermediate round or a final round is proportional to the ratio of the difference between an ideal game time and the elapsed game time;

a mechanical stop configured to be moved into the playfield to block a ball from entering a drain.

9. The method of managing a play session of claim 8 wherein the autosave is activated for a default amount of save time is used when the elapsed game time is minimal.

10. The method of managing a play session of claim 8 wherein the portion of the ratio of the difference between the ideal game time and the elapsed game time is a scaled factor relating to the initial, second, or final round.

11. The method of managing a play session of claim 8 wherein the portion of the ratio of the difference between the ideal game time and the elapsed game time is 25% for the subsequent round.

12. The method of managing a play session of claim 8 wherein the portion of the ratio of the difference between the ideal game time and the elapsed game time is 50% for the final round.

13. The method of managing a play session of claim 8 wherein the autosave further comprises a flipper automatically configured to be engaged in the playfield to block a ball from entering a drain.

14. The method of managing a play session of claim 8 wherein activating the autosave further comprises relaunching a ball without incrementing or ending the initial, second, or final round.
