Ritz Pinball Machine Review

(This is one of my first articles, written originally in 1995)

Ritz is one of the most beautiful, unique, unusual pinball machines I have ever seen. It is also one of the most boring. It is simple mechanically and has several interesting features.

backglass art

Ritz was built by the Stoner Manufacturing Company in October of 1938, according to the Pinball Reference Guide by Mueting and Hawkins. This particular game was serial number 122 and was first operated by Stewart Sales Company, 15 E. Bijou Street, Colorado Springs, Colorado. It appears to be a gambling machine with many of the same features of a bingo. Just above the out hole the manufacturer is identified as:

Stoner Mfg. Corp. - Aurora, Ill.
Made in United States of America
Pat. No. 2,093,293
Other Patents Pending


There are three odds windows and a tilt light besides the two rows of numbers in the back glass. The machine has five balls and uses the normal push rod ball lift mechanism. There is a ? hole and the machine will spot a random number if the ball enters this hole. The Ritz in the back glass lights up if the user is a winner, a signal to the keeper of the establishment that the player should be paid according to the lit odds window

Cabinet Design

One of the most unique features of this machine is the cabinet design. It is built like a console and has no legs. The cabinet actually is in two pieces. The normal box is supported by a skirt. The skirt can be removed and the box placed on a table or other support. The game looks like a single unit when placed on the skirt as the seam is almost not noticeable and the art work flows from one to the other. The art work is the best of the art deco era with wonderful curves and out lined colors, bright red, green, yellow, orange, and blue. Even the glass covering the play field has been painted on the underside and the play field with the glass covering tilts up to provide access to the internal mechanisms.


The instruction card reads:


5 Balls 5 cents

Insert coin, then shoot with skill to match the three (3) selections on back glass.

Matching three selections entitles player to points shown.

Lighting all lights (1 to 10 inclusive) entitles player to highest points shown in addition to intermediate points scored.

Hole designated by (?) is a mystery hole.

Points can be increased only by consecutive winners.

It is interesting to note the terminology. The machine awards "points" and does not explicitly talk about payouts. Yet the words on the meters inside the machine have notes that tell what each meter records. The terms talk about "payouts" for each position of odds on the back glass.


Play seems easy at first glance. The player puts in a nickel and pushes in the coin slide. The balls on the play field drop through holes and a whirring noise comes from the inside of the machine. The holes in the play field are blocked as the coin slide returns to the starting position. The numbers on the back glass flash in random order and suddenly settle with three of them lit. One of the odds lights in the center bottom is also lit. The whirring continues as there is a mechanical timer that allows you a maximum of five minutes to complete the game. The player can then lift and shoot the five balls in an attempt to match the numbers spotted by the game. There two rows of numbers from one to ten, the top row is the row the machine lights to provide a goal for the player to shoot for and the bottom row is lights to indicate which depressions the balls have landed in. This appears easy at first but notice the way the numbers are placed and their frequency, as shown in figure one!

playfield layout

There are three 4's and four 7's. There is only one 5 and one 8! It will be more difficult to match the specified three numbers if you have a 5 or an 8! Imagine how carefully you must place the balls if you want to light 1 through 10! I believe that the odds of the game are controlled by the number and location of the holes in the play field. There may be some control of the odds inside the machine, but I have not found any. There are no operator settings or plugs inside the machine. As a result, the player believes that it is necessary is to put the balls in the right depression to win and that each depression give two numbers. It looks easy! But the machine only gives certain numbers, perhaps appearing random, and some of the numbers on the field are difficult to make. There are five springs on the play field. These act like a rubber rings attached only at one end. It seems to take forever for the spring to catch a ball and rebound it in the new direction. The play is extremely slow because of the gentle springs, the minimal slant of the field, and the slow speed of the ball.

The letters "Ritz" in the back glass light up the instant the correct balls enter the depressions and the selection is matched. The user can finish shooting the last of the balls in the hopes of getting all numbers lit. There is a tilt light and this is connected to a slam switch on the front of the machine, a slam switch mounted to the bottom of the play field and to the plumb bob tilt on the mechanism board. There are notes stapled next to each slam switch that goes into great detail on adjustment. The switch on the front of the cabinet reads "The switch tilts the machine if the machine is give a sharp blow to bounce the ball back onto the playing field". The switch on the play field reads "The switch on the underside o f the overlay tilts the machine if the overlay is give a sharp blow".

Mechanical Workings

Ritz is very simple internally. It is all electromechanical, meaning it consists of wires, solenoids, and relays. The following picture describes the internal layout of the logic board.

The coin slide pushes on a reset bar that runs the length of the logic board. The payout relays are reset, the mechanical timer is wound completely, and the cam on the number spotting wheel is pushed enough to start the motor. This is where the random number is selected. Then the user is left to shoot the five balls. Each ball closes two contacts in the bottom of the slide board, illuminating the two equivalent numbers in the back glass. When the correct numbers are illuminated, the correct payout relay closes, lighting the "Ritz", and incrementing the payout counter.

Random Play

The randomness of the game deserves some description. The reset bar rotates a ratchet on a coarse ratchet wheel enough to rotate a cam with three depressions in it. The motor then turns on until one of the depressions is reached, thus turning the light selection contacts. There are 37 possible positions. The ratchet provides a coarse selection of the random position and the cam provides a fine adjustment. There are not that many combinations and the random selection is not random enough. A sharp player could break the bank and take the establishment if he could shoot the balls accurately.

Physical Description and History

The ball return tray was made out of scrap play fields. There was a portion of a beautiful play field used to direct the balls when they returned to the shooter.

I bought this game in 1989 for $175US. The serial number, 122, appears on the cabinet edge on the left side and on the bottom of the play field slide on the left side and is hand written in white. The name of the operator appears on the inside of the cabinet on the front and on the left side and appears to have been stamped with a rubber stamp. There are counters that measure the number of plays and wins at each of the odds. These counters show 1831 for first matches, 230 for a successive match, and 495 for completing all ten numbers. There is no indication on the total number of plays that was required to make these numbers.

The previous owner had brought it out to California from the East coast. I restored it mechanically and have played it only a little. The back glass shows no paint flaking off or fading. The mirror "paint" that outlines each number is still in perfect shape. The play field glass is flaking off in the areas where the glass touches the supporting wood. The play field paint is in perfect condition, probably due to the number of plays and the lack of ball action.


I restored the game. Restoration consisted of cleaning the play field and contacts. The play field has no wear spots or cracking, indicating premium wood was used as a base. The back glass has no flaking or cracking of the paint and the mirror effect is perfect. The glass covering the play field is painted in places and does have some paint flaking off. I cleaned the contacts on the wheels with contact cleaner and rebuilt the bearings and brushes on the electric motor. I replaced the rubber belt with a rubber ring. I have not been successful in finding a schematic. As a result the game still has a problem with lighting the "Ritz" in the back glass.

Innovations and Patents

The game seems to have provided a series of innovations. It is really a bingo and may be the first, predating Bally's Bright Lights by 12 years! The cabinet, with out legs, is unique. It had paint on the play field glass. It had extensive tilt and slam switches. I am not enough of an historian to determine if any of these are firsts.

Ritz has the following patent applied to the game. Patent number 2,093,293 was issued September 14, 1937 to Harry B. Stoner and Karl Knickerbocker. It consists of eight sheets of drawings and 14 sheets of text. It is fascinating reading! The drawings show a playfield layout, relay banks, ball sensing switches, kickers, and even a wiring schematic!

This invention relates to amusement or game apparatus of the type in which the player causes an object, such as a ball, to travel or to be projected over a playing surface which is provided with suitable areas or openings over or into which the object or ball may be moved. More particularly, the present invention is directed to that class of game apparatus, the operation of which is controlled by coin operated mechanism.

It goes on to describe the requirements for a game to have "player appeal" such as multiple objectives for the player, an "electrically operated visual indicating means", reward or score indicating how well the player is doing, and some random action to make each game different. The most unique aspect of the patent describes the ability for the player to set the objectives prior to start of play! Then the player must set out to and do exactly that. This was accomplished by a knob for the player to select certain objects.

This patent will be the subject for a future article and should be a part of every pinball library.
