UK Slot Machines for a US Audience
Introduction
As the saying goes, the UK and the US share a common language yet are divided by it. To clarify, what exactly does the term “ slot machine ” refer to? Literally speaking, it denotes a machine with a slot, which could serve a myriad of functions, but it's not always about money! Most commonly, it refers to a machine that operates by inserting cash. Many individuals further define it as a machine used primarily for gambling purposes, yet that interpretation isn't universally applicable.
We don't categorize machines like vending machines, ATMs, currency exchange machines, or washing machines as slot machines because they possess distinct names like 'vending machine.' Therefore, we venture into the realm of entertainment. This leads to a variety of perspectives, particularly in the UK, where it encompasses any amusement-oriented machine. Consequently, gambling as a form of entertainment is also included within this broader interpretation.
Early Differences
Now that we've outlined this, let’s discuss what we mean by amusement machines. I am certain that both the UK and US have numerous devices designed strictly for entertainment without any gambling aspect, however, that’s where our two countries begin to differ. This discrepancy largely stems from gambling regulations established in the late 1800s and early 1900s. In the UK, the regulation of gambling has been tightly monitored at a national level, particularly during the era when amusement devices first emerged, resulting in a diverse array of non-gambling machines appearing here.
Of course, from the outset, there was also a desire to create machines that served the gambling purpose. So, how was this achieved? By designing machines where it could be argued that skill played a significant role instead of pure chance. We had to convince the government to acknowledge this notion. Ultimately, they acquiesced and coined the term 'Amusements with Prizes' or AWP for short, while imposing rigid payout limits to ensure they didn't classify it as gambling. Therefore, while the U.S. was merrily introducing the classic spinning reel machines known for massive jackpots, we were crafting distinctly different versions.
While I could delve into an extensive discourse on vintage machines from the UK that could rival the length of 'War and Peace', this topic has been adequately explored elsewhere. Hence, I will keep it concise and encourage you to check out the following websites, which are filled with visuals and provide a better exposition on the topic than I could ever manage.
First off, let me clarify that we didn't innovate all the foundational concepts behind our machines; most originated in Germany, but we certainly embraced and improved upon them! If you're interested in 'for amusement only' machines, I recommend exploring the links provided above, as I will focus on AWP machines, considering that the readers of 'The Wizard' are likely more interested in how to win!
The most prevalent format for AWP machines is what became popularly known as the Allwin. This name has become generic much like 'Biro' for ballpoint pens. Although most ballpoint pens aren’t produced by the Biro company, people still refer to them as biros. Allwin emerged from the earliest machines where the marketing slogan claimed, 'All cups are winners,' which was eventually abbreviated to Allwin and became a catch-all term. But what does 'All cups are winners' signify? Let's take a peek at a vintage machine to find out.

When you insert a penny into the designated slot on the right side, a ball bearing falls from a small opening at the bottom right behind the glass panel. You then utilize the trigger at the bottom right of the machine to propel the ball along a broken spiral track. There are three outcomes possible:
- The ball bounces back to you, allowing you to launch it again.
- The ball lands in the small hole at the bottom of the innermost curved section of metal, which indicates a loss.
- The ball lands in one of the cups, and since 'all cups are winners', you have secured a win.
If fortune smiles upon you and you win, you simply turn the payout knob located at the bottom left of the machine a full turn, causing the standard payout to trickle into the coin slot at the middle bottom of the cabinet.
Essentially, that's how all Allwin machines operate. They include a vertical track that propels a ball towards various target holes, cups, or channels that determine the game's fate.
Isn't it straightforward? Yet, the variations on this theme are astonishing! What aspects can differ? The specific configuration of the ball track might change, potentially not even resembling a spiral. Individual targets may offer different payouts. The number of balls in play may exceed one, with some machines employing multiple balls simultaneously. Certain models came with a feature for a 'free ball after winning.' The visual design of the machine could be any artistic creation. The payouts aren’t restricted to cash! Variants of these machines have dispensed chocolate bars, mint tubes, cigarettes, and other small prizes. The targets might include holes, cups, catching forks, tipping levers, channels, or a 'gallery' of channels separated by pins embedded in the machine's backing. Some machines featured more than one gallery. Here’s a glimpse of a gallery from my own machine.

My machine is modern, custom-built by a designer, and based on a very common design known as a Fivewin. This designation comes from the fact that the gallery features two losing channels but five winning ones as mentioned earlier. Depending on the different payouts offered by the various channels, you need to turn the payout knob multiple times according to what the decals indicate to receive your complete payout. Since I'm merely engaging with my own funds, I've enabled the free ball feature. Retro Arcade As another illustration, let me show you one more example, which demonstrates that the ball track doesn’t always have to follow a spiral format.

This particular design is known as Boomerang. Please don’t ask me how it operates, because I have never tried it!

As previously mentioned, there have been numerous designs in addition to Allwins, and as time progressed, the emergence of electro-mechanical machines caused a significant explosion in design variety. However, many of these were simple chance-driven games that required licensing to operate. With that, we can transition to discussing the traditional 3-reel slot machine.
Current and former distinctions
When mechanical 3-reel slot machines finally made their debut in the UK, primarily influenced by German designs before our local adaptations took over, they closely resembled the models found in the U.S. Yet, a majority of them only accepted tiny stakes and had minimal payouts. Finding serious gambling machines, similar to those recognized by American audiences, required membership in private clubs since casinos weren't prevalent at that time. This was a result of licensing regulations, rather than the design of the machines.
Similar current and past differences

As was the case with AWP machines, electro-mechanical machines soon dominated the 3-reel slot machine market, leading to further deviations from U.S. standards. Some ideas have since crossed back over the Atlantic, but I’m referring to a time long before that exchange occurred. The first significant deviation occurred almost right away with the introduction of Hold buttons located beneath each reel. These buttons would light up randomly after a coin was inserted, but not immediately in the wake of a win. This allowed players to keep one or two symbols from the prior spin (three would be illogical). If players reconsidered their choices, a Cancel button was provided to adjust selections. The competitive nature of the industry quickly led to the inclusion of 'Hold after Win' functionality.
To maintain an edge in the market, Nudge buttons were introduced alongside a display that indicated the number of nudges available to the player, which was also determined randomly. This feature allowed players to shift any of the reels one symbol at a time to attempt to create a winning combination within the set number of nudges. As with the Hold feature, the triggering of nudges happened at random. Naturally, understanding the reel layout became crucial for gameplay, except for casual players who often peered up the reels in hopes of predicting the next move. It wasn’t long before a second set of Nudge buttons emerged, enabling players to nudge the reels upward, which could be used in conjunction with the nudge-down buttons.
These functionalities became so widely embraced that for decades, it has been uncommon to find a new UK machine that doesn’t feature both Hold and Nudge Down and Nudge Up buttons. The market has essentially made them indispensable.

Given that people often say the UK and the US are divided by a shared language, let’s clarify what is meant by “
” at its basic interpretation, it refers to a device featuring a slot, which could serve various functions, not limited to just accepting money! Nonetheless, it’s generally understood that it pertains to a machine activated by inserting money into a slot. Many assume, accurately or not, that such machines are designed primarily for gambling. However, that viewpoint is not entirely accurate. D gaming machines We don’t categorize machines like vending machines, ATMs, currency exchange machines, or washing machines as slot machines since they have distinct, widely recognized names, such as “vending machine.” Thus, we narrow our focus down to the realm of entertainment. Here in the UK, this includes any device intended for amusement, meaning that gambling, as a type of entertainment, fits within that broader definition.
Street talk
Now that we’ve established that, what do we mean by amusement machines? It’s important to note that both the UK and the US have various devices labeled as “for amusement only” that do not involve gambling. However, this is where the two countries diverge, primarily because of differing gambling regulations in the late 19th and 20th centuries. In the UK, gambling has historically been tightly regulated at the national level, especially during the inception of amusement machines. This led to the development of machines designed for amusement only in various forms.

Nonetheless, our desire for gambling machines persisted. So, how did we achieve that balance? By crafting machines that claimed to incorporate a significant element of skill as opposed to relying solely on chance. We then lobbied the government to accept that premise. The government eventually acquiesced and introduced the designation “Amusements with Prizes,” or AWP for short, which came with stringent payout limits to prevent what they perceived to be gambling. While the US was enthusiastically creating rotary reel machines known for their large jackpots, we were focused on crafting a different breed of machine.
At this juncture, I could delve deeply into the topic of vintage UK machines, which could become a significant narrative in its own right, akin to a lengthy novel. However, that subject has been explored extensively elsewhere. Briefly put, I encourage you to check out specific websites filled with numerous images that provide a much richer exploration of this topic than I could offer.
To clarify, we did not originate the fundamental concepts that formed our machines; most ideas trace back to Germany, but we definitely expanded upon them with greater enthusiasm! If you’re interested in machines designed purely for amusement, I recommend exploring the links provided above, while I choose to focus on AWP machines, as it’s likely that “The Wizard’s” audience is more intrigued by the possibility of winning!
Playing tips
The prevailing and nearly universal type of AWP machines is referred to as the Allwin. This term has become generic, just like the term Biro is used for most ballpoint pens, even those not made by Biro. The name Allwin originates from early machines showcased with the slogan “All cups are winners,” which was eventually shortened to Allwin and became a common reference. What does “All cups are winners” imply? Take a look at the design of one such early machine.
