Gamblorium is an independent online casino affiliate platform, aimed at providing transparent and honest ratings of real money online casinos. To achieve this goal, Gamblorium has developed a rating system called Gamblorium Rating.
Gamblorium Rating includes over 100 parameters for evaluating online casinos, which are thoroughly checked during testing. The testing process starts with accessing the site and registering, and ends with withdrawing funds to an account: Gamblorium experts experience the process as a real player.
The transparency of the rating is ensured by the fact that Gamblorium openly describes the methodology for evaluating online casinos and each group of characteristics that impact the final rating. One of the main goals of Gamblorium is to ensure maximum independence of the rating and the positions in online casino listings. This is what sets Gamblorium apart from other affiliate platforms in the online gambling market.
How We Calculate Gamblorium Rating
To achieve the independence of Gamblorium Rating, the team of experts strives to minimize the influence of our subjective opinions by aggregating as many verified data from open sources as possible, and also through testing, where we only confirm or disprove the claims made by online casinos, providing only accurate and honest information. Additionally, our online casino rating consists of three components: Gamblorium Score, Player Score, and Market Score.
Gamblorium Score is the rating provided by the team of researchers, analysts, and experts on online casinos of the Gamblorium affiliate platform and is one of the three components that make the final rating more objective and independent.
Player Score is a rating based on the aggregation and automatic analysis of interactions with real players of online casinos, who further validate the provided data by leaving their reviews and ratings. Each review left is validated to ensure that it was made by a real player, registered on Gamblorium, and having experience with the specific online casino.
Market Score is a weighted rating of other authoritative gambling affiliate platforms and online casino review sites, which, according to players and our team, are expert sources of information in the industry.
This is how Gamblorium ensures a fully transparent, objective, and independent algorithm for obtaining Gamblorium Rating, leaving the decision-making to the participants of the gambling environment, with Gamblorium’s influence accounting for approximately 33.33%.
Thus, Gamblorium Rating = (Gamblorium Score + Player Score + Market Score) / 3. The maximum value that Gamblorium Rating can take is 100, while the minimum value is unknown, as Gamblorium Rating is relative, and our team does not assign direct ratings to online casinos.
To ensure maximum transparency of the rating, we provide detailed information about how we derive Gamblorium Score, which directly impacts the Gamblorium Rating. The calculation of Gamblorium Score is based on two principles: relativity and weighted evaluation.
How Relativity Affects Gamblorium Score
Relativity of the rating means that for each parameter of Gamblorium Score, we identify the online casino where this parameter is best represented, and that casino receives the highest rating (usually 100). Other online casinos in this category receive lower ratings, relative to the best one.
For example, if Casino A receives a rating of 100 for the number of game developers it offers, and it has 50 developers, then Casino B, which has 40 developers, will receive a proportional rating of (40 x 100) / 50 = 80.
In reality, we do not simply count the number of developers, and coefficients are also involved in the calculation algorithm, ensuring maximum objectivity when obtaining the final Gamblorium Score.
Understanding Weighted Evaluation and Coefficients
Gamblorium implements coefficients in the evaluation algorithm to adjust the influence of various factors on the Gamblorium Score, which allows for a more precise and objective assessment.
For example, let’s consider Payment A, which is offered in an online casino. Payment A is a popular local payment option, supports local currency, has no fees, is integrated with a local bank, and is both safe and fast. Payment A may be assigned an importance coefficient of 1, 2, or even 3 (the same payment method may receive different coefficients in various markets).
On the other hand, Payment B is a cryptocurrency option, which has its advantages but is not as fast, often includes blockchain transaction fees, and is not always the most secure, being more anonymous and convenient. Additionally, online casinos may integrate numerous cryptocurrency options, giving them a significant influence on the Gamblorium Score. In this case, Payment B may be assigned a coefficient of 0.2, 0.5, or another value, but less than 1.
To fairly calculate the Gamblorium Score, it is insufficient to use a simple arithmetic average, and thus a weighted score is applied. In this way, the components of the score are calculated as A = A1 × W1 + A2 × W2 + … + An × Wn, where A1, A2, A3 are the rating parameters, and W1, W2, W3 are the importance coefficients of these parameters according to the Gamblorium experts.
Gamblorium Score Calculation Methodology
Gamblorium Score consists of several groups of parameters, each of which has been maximally detailed to achieve minimal variance in the ratings.
Online Casino Financial Metrics [A]
The ways in which a player can deposit or withdraw winnings to their account are one of the most important groups of parameters in the Gamblorium Score, though not the only one. This group also includes other important parameters.
- Payment Methods Availability
- Gamblorium does not simply evaluate the number of payment methods, but also considers their importance for each local market and the characteristics of these options. The Gamblorium experts’ principle is that the more payment methods offered by an online casino, the higher the rating it receives.
- Minimum and Maximum Deposit Limits
- For a certain group of players, the availability of low minimum deposits in online casinos is a decisive factor. Therefore, the lower the minimum deposit, the higher the casino’s rating. At the same time, the maximum deposit is also important — the higher the maximum deposit limit in the online casino, the higher the rating for this parameter.
- Minimum and Maximum Withdrawal Limits
- For players, the minimum withdrawal threshold is crucial, especially when receiving a win from a bonus or with low deposits. An online casino that offers a low withdrawal threshold receives a high rating. The maximum withdrawal amount is also considered: the higher this limit, the higher the casino’s rating.
- Currency Availability
- The more currencies are offered by an online casino, the higher its rating. Gamblorium especially pays attention to the presence of the local currency, as its absence lowers the rating, while its presence significantly increases the online casino’s score.
- Withdrawal Speed
- The speed at which withdrawals are processed plays a crucial role in the evaluation. The faster the transaction is completed and the shorter the pending time, the higher the online casino’s rating.
- Additional Financial Parameters
- We also take into account additional parameters, such as the presence of fees for deposits or withdrawals and the ability to use an internal currency exchange. The option to cancel a transaction is also considered a positive factor that adds convenience and transparency. Other important parameters are also taken into account.
Online Casino Payout Rate [B]
One of the most important indicators for an online casino is its Payout Rate. This refers not only to the fairness of the casino, but also to a measure based on a set of specific characteristics. Gamblorium uses two approaches to calculate the Payout Rate of each online casino tested in our rankings — theoretical and practical.
- Theoretical Approach
- The theoretical approach is based on mathematical calculations using open data declared by game developers. Gamblorium’s database includes RTP data for every well-known online slot in the gambling market. We calculate the average RTP for each game developer, then analyze the online casinos and compile a list of the developers available in each casino.
This allows us to calculate the theoretical Payout Rate for each online casino. This value is probabilistic but fully backed by mathematical calculations.
- Practical Approach
- The practical approach involves analyzing statistics from open data provided by players in our partner panel from the beginning of online casino testing. We examine the sum of all deposits known to us and the sum of all winnings made by players.
The ratio of these two sums gives us an understanding of what the Payout Rate is in a particular online casino. It is common for the sum of winnings to exceed the sum of deposits, as players often win at online casinos. Therefore, Gamblorium may report a Payout Rate greater than 100%. Unlike the theoretical approach, this is not possible in the theoretical method, but which approach to rely on is for each player to decide. Gamblorium only compares these values and ranks online casinos relative to each other, with the situation possibly changing daily.
Online Casino Bonuses [C]
Online casinos offer various bonuses as part of their marketing campaigns, which is one of the defining features of their competitiveness. Therefore, Gamblorium also takes bonus offers into account when calculating the Gamblorium Score.
To evaluate bonus offers, we use a similar complex yet transparent calculation system as for Gamblorium Rating. This includes Gamblorium Bonus Rating, which evaluates numerous important aspects.
- Bonus Program Variety
- One of the key parameters for Gamblorium Score is the availability of a variety of bonus offers in an online casino. The more bonus options and opportunities are provided to players (both new and existing), the higher our rating will be. We consider not only the availability of different types of bonuses but also the series of bonuses of the same type — for example, a welcome bonus for the first deposit or a series of bonuses up to the 10th deposit.
- Bonus Value
- Gamblorium assesses the generosity of the bonus packages provided to players, taking into account such components as the percentage match size, the number of free spins, the minimum deposit required to receive the bonus, and in some cases, additional components such as the cashback percentage for cashback bonuses.
- Bonus Wagering Requirements
- One of the most important parameters for Gamblorium Score is the transparency and fairness of bonus wagering requirements. Often, attractive bonuses hide harsh wagering requirements, such as 200x, which is extremely unfavorable for players. We favor casinos with wagering requirements in the range of 30x-35x and verify what is hidden behind these conditions.
It is also important to note that wagering conditions may vary. For example, 35x could mean wagering the bonus portion only, or it could also include the deposit, which doubles the wagering requirements. We consider such nuances when evaluating.
- Bonus Terms Clarity & Transparency
- The clarity of bonus terms is a key factor, as they often hide significant details in fine print. We carefully examine such terms and identify “red flags” that negatively affect the rating. Gamblorium adheres to the principle of honesty with players, and if we find potential hidden traps, it reflects in a lower rating in Gamblorium Score.
- Other Non-Obvious Bonus Parameters
- In addition to the primary characteristics of bonus offers, there are other factors that play a role in our evaluation. For example, restrictions on receiving bonuses depending on the player’s device or payment method used, such as with Skrill and Neteller. We certainly pay attention to such nuances.
Also, we take into account the maximum cashout, which is often limited to small amounts, making bonuses less beneficial for players. Another important aspect is whether the bonus is cashable or sticky (of course, Gamblorium rates cashable bonuses higher).
Online Casino Entertainment Variety [D]
Games are the core element of online casinos, and this is one of the most important factors influencing the Gamblorium Score. This includes several key parameters.
- Game Developer Count and Quality
- The more game developers an online casino offers, the higher its rating will be. However, Gamblorium Score also considers the quality of these developers. We place more importance on those who offer diverse online slot mechanics, engaging scenarios, and well-balanced betting systems, and we lower the rating for those whose games are repetitive and have low RTP values.
- Entertainment Variety
- While online casinos typically include online slots, players are also interested in other games such as online poker, roulette, bingo, and blackjack. The presence of each of these types of games in an online casino increases its rating. We also consider the availability of betting on sports events and various lotteries.
- Game Selection
- The more diverse games an online casino offers, the higher its rating will be. It is important to consider not only the number of games but also the quality of developers offering these games.
- Exclusive Games Availability
- The presence of exclusive games is an additional plus for an online casino. While these games may not always be hits, they add variety and encourage player attention, which contributes to a higher rating.
Gamblorium Score Calculation Formula
For the final Gamblorium Score calculation, we use a weighted approach described earlier, but this time on a higher level.
Thus, Gamblorium Score = A x W1 + B x W2 + C x W3 + D x W4, where:
A – Online Casino Financial Metrics (the metrics of online casino regarding deposit and withdrawal capabilities).
B – Online Casino Payout Rate (the potential payout rate of the online casino, calculated using theoretical and practical approaches).
C – Online Casino Bonuses (the metrics of online casino regarding the types and conditions of bonuses provided to players).
D – Online Casino Entertainment Variety (the parameter of the breadth of game developers, their games, and additional game types or exclusive games available in the online casino).
W1, W2, W3, W4 – the weighting coefficients of each parameter’s influence on the Gamblorium Score, relevant to their importance according to our team’s experts.
This is how Gamblorium applies its methodology for calculating online casino ratings and ranking them in listings on its affiliate platform pages. This is truly a transparent, lab-based approach to building ratings.
