Black Knight' introduced 'Magna-Save' and the Bonus Ball concept where the player with the highest score won additional seconds of free play. Magna-Save was a feature where a user could press a button on either side and magnets would prevent the ball from draining via that outlane. It would stop and hold the ball and drop it into the inlane. The user had to perform some task to re-enable magnasave.
'Black Knight' was the first solid state game with a multi-level playfield. Examples of earlier games with multi-level playfields are Fisher & Coe Manufacturing Company's 1933 'Grand Central' and Chicago Vending Company's 1934 'Three Point'.
