22
, ball contact end
24
, and an intermediate body having a compression spring
25
, is collinearly mounted through housing
11
along the longitudinal extent of launch guide
20
′. When knob
23
is fully extended, ball
0
exits launch guide
20
′, and is first expelled by releasing knob
23
. Once ball
0
exits launch guide
20
′, it is in play and may come into contact with wall
14
, pins
18
and enters first slots
19
. The object of the game is to enter into a selected slot
20
. Each slot
20
is provided with a sensor
21
, which is associated with a microprocessor that contains a program which activates or deactivates a sensor
21
in one or more of the slots
20
with each game so that the player would be required to alter his playing strategy with each game. In addition, the microprocessor provides each slot
20
with a value so that the same score will reflect the player's skill in being able to enter a given slot
20
.
Along the upper part of the housing
11
and along the top wall
14
is a display board
32
, which is associated with a microprocessor to provide the score and a visual display on screen
33
in accordance with the play on the playing field and the sensors
21
activated by a ball
0
. At least one sensor
21
provides a bonus score and is displaced by an LED. The microprocessor is also programmed to deactivate a sensor
21
so that when the ball enters a deactivated slot, the play is lost. The microprocessor is further programmed to count the number of balls
0
which enter the slot so that the odds are changed and the player must develop a different strategy. If the ball
0
rests on a lighted slot, the sensor signals the microprocessor, which senses the display board
32
and displays the cumulative score. Generally, there are sixteen slots
20
on the playing field and at least four of the slots
20
are activated and lit by an LED so as to display a slot that allows scoring.
Along the playing field are a plurality of pins
18
, which randomly direct the ball to slots
19
and
20
. The size and shape of the pins as well as their positioning on the playing field have an effect on the ball and the odds of a ball going to a specific slot.
