How Much Money Can A Slot Machine Hold?

Slot machines have long been a popular form of entertainment in both physical casinos and online platforms. These machines, also known as one-armed bandits, are designed to take in more money than they pay out, ensuring a profit for the casino. But have you ever wondered just how much money a slot machine can hold? 

How Much Money Does A Slot Machine Hold?

A slot machine's capacity varies. It has to ensure it can cover numerous maximum payouts if they occur. Generally, they're designed to hold thousands of pounds, with high-limit machines potentially storing even more. This ample capacity guarantees the ability to award multiple top payouts in the event numerous large wins hit in a short space of time. This safeguards the machine's functionality and accommodates potential wins without running out of funds. 

The amount of money a slot machine can hold at any given time is also determined by its hold percentage. The hold percentage refers to the portion of the betting coins that the casino keeps for itself. This percentage is primarily influenced by the Return To Player (RTP) rate of the slot machine. 

What Is The Hold Percentage On A Slot Machine?

The hold percentage on a slot machine refers to the portion of the wagers placed that the casino retains as profit. It is calculated over a long period of time and is an estimated indicator of the casino's potential profit from the slot game. The hold percentage is not directly related to the capacity of the slot machine to hold physical money. 

The hold and RTP rate of a slot machine go hand in hand. For instance, a slot machine with a 95% RTP rate would have a 5% hold. This means that for every £100 wagered, the slot machine holds £5. However, it's crucial to understand that the hold and RTP rates are not linear, and the actual amount you may lose while playing a 95% RTP slot can vary. 

It's worth noting that the hold percentage is different from the house edge. The house edge represents the advantage the casino has over players in a particular game, while the hold percentage indicates the potential profit the casino may make from a specific slot machine. 

Return To Player (RTP) Explained

The Return To Player (RTP) rate is a crucial factor to consider when choosing which slot games to play. The RTP rate of a slot machine is the percentage of money it should, in theory, pay back to players over time. 

RTP rates can vary significantly from one slot machine to another. They are usually expressed as a percentage and can range from around 70% to over 99%. However, it's important to note that the RTP rate will never be 100%, as the casino needs to make a profit. 

For example, a slot machine with an RTP of 95% means that it should average out as paying out £95 for every £100 it takes in. The RTP rate is calculated by the slot's developer over a large sample of simulated spins. However, it's important to note that the RTP rate is an average over a long period of time and may not be reflected in short sessions of play. 

In short gaming sessions, players may win more or less than the indicated RTP rate, or they may win nothing at all. 

Does A Slot Machine Have To Pay Out When Full?

Contrary to a common myth, slot machines do not have to pay out when they are full. The idea that a slot machine's capacity is related to its payout is a misconception. Slot machines operate based on a Random Number Generator (RNG) chip, which ensures that the results are completely random and independent of previous spins or external factors such as a slot machine's available capacity. 

The RNG chip generates random numbers or symbols that determine the outcome of each spin. It is impossible to predict or manipulate when a slot machine will pay out based on its physical capacity or the number of coins it holds. The sound of coins dropping into the machine's internal cash storage is simply a mechanical process and not an indication of an imminent payout. 

The only time a slot machine pays out is when a winning combination is formed, or a jackpot is triggered. The results of each spin are entirely random and not influenced by external factors such as the number of coins in the machine. 


In conclusion, the amount of money a slot machine can hold can vary from one machine to the next. Then, there is the hold percentage, which represents the portion of wagers that the casino retains as profit. However, the capacity of a slot machine does not determine its payout frequency or the likelihood of winning. Slot machines operate based on random outcomes generated by the RNG chip, making them unpredictable and independent of previous spins. 

Remember, slots are random games of chance in which winning is never guaranteed.
