Unique bingo. The Hifi is the only bingo that has the disposal of the so-called "Bump" feature.
By speeding up the machine, "Bump" might lit up on the backglass. Now you can jiggle the playfield by pressing the green bump-buttons - that are situated on the sides of the cabinet - to swerve the ball into an already passed hole. The maximum of bumps allowed is 10.
More possibilities the Hifi offers are, among others, 2 supercards (3-in-line scores 4-in-line), Select a number (by turning the selector-knob on the front of the cabinet you can choose one number from the series: 19-20-21-22-16-25-10), Corners score (four corners scores 200 points), and finally, 3 extra balls.
