What is a high-roller in casinos?
In the world of casinos, the term ‘high-roller’ refers to a player who regularly wagers sums far greater than those of an ordinary customer. Also known as a ‘whale’ in casino jargon, this high-stakes player often enjoys preferential treatment.
A high-stakes player recognised by the casino
A high-roller is not simply someone who places a large bet in the course of an evening. This status is generally based on regular play, high stakes and the ability to withstand substantial losses.
There is no universal threshold that automatically qualifies someone as a high-roller. Each casino sets its own criteria based on its size, clientele, betting limits and financial capacity.
At Crown Casino in Australia, for example, a player had to bring between 50,000 and 75,000 Australian dollars to a table to be considered a very high-value customer. Maximum limits can then reach much higher levels. In Australia, limits of 300,000 Australian dollars are common in specialised gaming areas. In Las Vegas, the limits mentioned range from 150,000 to 300,000 US dollars. In Macau, they can reach 500,000 US dollars.
Only casinos with sufficient financial resources can cope with this volatility.
How do casinos identify these players?
Casinos closely monitor their customers’ behaviour. In particular, they take into account the average stake, the duration of gaming sessions, the frequency of visits and the amounts wagered over time.
Someone who regularly gambles at very high stakes can be quickly identified and enrolled in a VIP programme. They are sometimes assigned a personal manager responsible for organising their stays, travel arrangements, bookings and access to private gaming areas.
This status is primarily granted by the casino. It is not an official title that a player can claim after a single exceptional bet. A person may wager a large sum on a single occasion without being considered a high roller. Conversely, regular play at high stakes quickly attracts the attention of the sales teams.
High rollers are generally associated with games that allow for large bets, such as baccarat, blackjack, roulette or poker. However, the game chosen is not sufficient on its own to determine this status. It is primarily the volume of money wagered that counts.
Why do casinos offer them so many benefits?
The privileges granted to high rollers may give the impression that establishments are spending lavishly. However, these services are calculated based on the player’s expected financial value.
A casino may offer private gaming areas, personalised limits and round-the-clock assistance. Some establishments also offer limousine transfers, private jet flights, luxury suites, meals, drinks and tickets to shows. The level of benefits generally depends on the type of game, the average amount wagered and the time spent playing. Establishments may track activity using a loyalty card to assess the customer’s behaviour.
The calculation is not based solely on actual losses recorded. Casinos also use the concept of theoretical loss. This corresponds to the amount a player is statistically likely to lose over a long period, taking into account the casino’s mathematical advantage. The higher the total volume of bets, the greater this theoretical loss becomes. The casino can therefore cover the cost of a room, a meal or transport whilst maintaining a favourable expected return in the long term.
Among the most sought-after incentives are partial refunds of losses. A casino may refund a portion of the sums lost over a specified period to encourage the player to return.
Casinos may also grant credit. In this case, the player continues to place bets using an advance that they will have to repay at a later date. This option significantly increases the risks, as it allows a game to continue even after the player’s available funds have been exhausted.
However, the benefits are conditional. When a high roller reduces their stakes, spaces out their visits or chooses a rival casino, the level of service they receive may diminish.
Do high rollers really keep casinos afloat?
The popular image of a casino is often based on a few billionaires surrounded by personal assistants, gambling away fortunes in a private lounge. Yet high rollers represent only a fraction of the clientele.
In his book on legalised gambling in the United States, John Eidsmoe states that the wealthy occasional gambler does indeed exist, but that they are the exception rather than the norm. He points out that slot machines account for a very significant proportion of Nevada’s revenue, suggesting that high rollers are not necessarily the sector’s main source of income.
Customers who place modest bets are far more numerous. The cumulative total of their spending can therefore amount to more than the spectacular winnings of a few wealthy individuals.
High rollers remain, however, a strategic asset. A single session can generate considerable financial turnover. Their presence also contributes to the image of prestige that certain establishments seek to maintain.
Special treatment that is sometimes controversial
The pursuit of high rollers has already sparked regulatory controversies. Establishments may grant them terms and conditions that are not available to the rest of the clientele.
In Melbourne, for example, the areas reserved for high rollers at Crown Casino were granted an exemption from the state-wide smoking ban. This difference in treatment illustrates the commercial clout of these customers.
The desire to attract wealthy players from overseas has also drawn the attention of the authorities. A royal commission held in 2021 in the Australian state of Victoria concluded that Crown Resorts had worked with intermediaries tasked with bringing in wealthy players from mainland China. According to the commission, some of these intermediaries had links to organised crime.
The Terrance Watanabe case: a symbol of excess
The story of Terrance Watanabe is one of the best-known examples of the dangers associated with high-stakes gambling. This American businessman is said to have lost more than $220 million in Las Vegas over a five-year period.
His case took a legal turn when Caesars Entertainment demanded repayment of $14.75 million in advances granted to him so that he could continue gambling.
The case also called into question the casino’s practices. The regulatory authorities fined Caesars $225,000 for allowing Watanabe to continue gambling whilst he was heavily intoxicated.
Several cases recorded in various countries also involve players who have committed fraud to finance a lifestyle or bets they were no longer able to afford. The prestige associated with high-roller status can thus mask deep debt.
High-rollers and strategic players: two different profiles
A player who bets heavily is not necessarily a professional capable of beating the casino. The majority of high rollers are happy to take part in games where the house has a mathematical advantage. Their priority may be entertainment, prestige, access to private areas or the thrill provided by high stakes. They generally have substantial financial resources, but this offers no guarantee that they will win more.
So-called ‘edge’ players follow a different approach. They seek to reduce or overcome the casino’s edge through strategy, discipline or by selecting specific situations. This profile remains in the minority and does not fit the usual definition of a high-roller.
A world of luxury built on very real risk
The high-roller occupies a spectacular place in the collective imagination of casinos. They sometimes travel at the establishment’s expense, stay in the finest suites and play away from the public eye, accompanied by a personal manager. But gifts, reimbursements and credit do not eliminate either the establishment’s mathematical edge or the risk of significant losses. Above all, they make the experience more comfortable and encourage the player to remain loyal.
Being regarded as a high-roller does not, therefore, mean being a better player. Above all, it means regularly wagering sums large enough to be considered a priority customer in the casino’s eyes.
In Belgium, the benefits offered to players are strictly regulated
Unlike some major gambling markets, Belgium imposes particularly strict rules regarding the benefits offered by casinos. The legislation prohibits licence holders from offering, free of charge or at below market price, travel, meals, drinks or gifts intended to attract or retain players. This ban also extends to free entry to games, gaming credits and any other benefits likely to influence players’ behaviour. In other words, loyalty schemes and privileges granted to customers, including high rollers, must comply with a legal framework designed to limit incentives for excessive gambling.
