How We Rank Bonuses

How We Rank Casino Bonuses using BonusRank

Not just any online casino makes the grade. We have a strict process for testing online casinos to determine whether we even list them.

Once we approve a casino, our team of experts starts the real work. And it's thorough. Our unique BonusRank algorithm considers all the important aspects of a bonus and calculates a score that allows meaningful and direct comparison between bonuses. You don't have to guess, our rating scale will clearly show you if a bonus is great, good enough, or should be avoided.

Read more about our BonusRank system and how we make bonus comparisons.

What is Our BonusRank System?

We've developed an advanced bonus ranking system that enables us to assess and compare an enormous database of current casino bonuses. We can comprehensively analyse each offer with speed and accuracy, discarding subpar bonuses and prioritising the most competitive and value-led ones.

How, exactly, do we achieve this? It’s all about data points.

We set aside all subjectivity and bias and evaluate the most important bonus metrics. Our algorithm scores all these matrics and produces a score ranked from 1 to 100. Naturally, 100 is the highest, and the scale indicates how likely you are to yield a positive result if you choose the bonus.

Our unique data analysis allows us to grade and review bonuses in real time without bias, ensuring transparency and fairness. Most importantly, this system empowers you to easily compare bonuses and choose offers that give you the biggest chance of cashing out real winnings - guaranteed.

To make things even easier for you, we translate these metrics into a visual system that’s quick to scan.

Ultimately, it will empower you to instantly make decisions on things like:

  • Is this the right bonus for you?
  • Does it allow gameplay on genres that interest you?
  • What’s the most you can win?
  • How easy is it to win?

We Use Metrics Based On Data From MoreThan 2,000 Casinos

We have meticulously gathered bonus data from over 2,000 casinos. Our database undergoes continuous updates to guarantee that we offer our readers the most current and precise information.

Utilising this data, we establish averages that serve as benchmarks when evaluating carefully selected metrics to assess and grade bonuses.

These are the metrics we assess:

  • Bonus amount- The total monetary value of the bonus offered to players without requiring a deposit.
  • Bonus percentages- The percentage of the bonus amount relative to the deposit or wagering requirement.
  • Bonus match value- The percentage at which a casino matches a player's deposit with bonus funds
  • Number of free spins- The number of free spins awarded to players as part of the bonus offer.
  • Cash-out limits- The maximum winnings a player can withdraw from the bonus offer.
  • Wagering requirements- The number of times a player must wager the bonus amount before being eligible to withdraw any winnings.
  • Game contribution percentages- The percentage of each wager that contributes towards meeting the wagering requirements, which varies depending on the game type.
  • RTP percentages for eligible games- Return to Player (RTP) percentages specify how much of all placed bets a game returns to players as winnings over time. For example, if a slot has an RTP of 96%, it means that 96% of all stakes are distributed as winnings. The remaining 4% is known as the house edge which is basically the casino’s profit.

The BonusRank Scoring System

Each metric is individually assessed and graded from 20 to 100 based on a scale we have designed. Depending on this bonus type, we will use different metrics. For example, for match bonuses we consider the match percentage, which is not relevant to other bonus types.

The final scores can be interpreted as follows:

ScoreGradeInterpretation
81-100 pointsExcellentUnusual, exceptional - we highly recommend this bonus
61-80 pointsGoodAbove average, certainly worth playing with
41-60 pointsAverageNot great, only play this bonus if you really want to test the casino or a specific game
21-40 pointsPoorSubpar - there are numerous better options

Bonuses scoring 81-100 are considered excellent, surpassing our expectations and significantly enhancing the gaming experience.

Bonuses in the 61-80 range are deemed above average, offering reasonable value but falling short of greatness.

Similarly, bonuses earning 41-60 points are considered moderate; they may not be extraordinary, but they serve their purpose adequately. However, you should avoid bonuses with poor grades, as there are plenty of better options to choose from.

About The Bonus Metrics

When evaluating a bonus, we look at specific metrics that we know provide value to players. By assessing and scoring each metric, we can accurately establish a bonus’ true value and see how it compares to other offers on the market. Read on to learn about which metrics we look at and why they're important.

The Bonus Amount

The bonus amount refers to the total value of the bonus offered by the casino, typically expressed in monetary terms. While the total bonus amount plays a significant role in determining the attractiveness of a bonus offer, it's important to note that it is not the sole factor to consider.

Applied to: No Deposit Bonuses

The Bonus Percentage

A bonus percentage reflects the amount of your deposit that will be matched with bonus funds.

Applied to: Match Bonuses

The Bonus Match Value

A bonus match value refers to the maximum amount of bonus funds you can get, irrespective of how much you deposit.

Applied to: Match Bonuses, Match Bonuses With Added Free Spins

The Number Of Spins

The number of spins refers to the amount of free spins you will receive as part of a bonus.

Applied to: No Deposit Free Spins, Match Bonuses With Added Free Spins

Metrics For Terms And Conditions

Once we've determined the value of a bonus or free spins offer, we evaluate its associated terms and conditions to ensure transparency and fairness.

Our comprehensive BonusRank system considers several factors, such as wagering requirements, cash-out limits, game contribution percentages, and RTP percentages of the eligible game(s).

Below, you can find more details about each metric and the bonuses they assess:

Wagering Requirements

Always kick things off by assessing the wagering requirements of a casino bonus. They determine how many times you must wager the bonus funds before they can withdraw any winnings.

As a metric for assessing bonus value, lower wagering requirements are generally more favourable as they make it easier for you to meet the conditions and cash out your winnings. High wagering requirements can make it challenging for players to fulfill the terms and may lead to frustration.

Applied to: All bonuses except wager-free bonuses

Cash Out limits

Cash-out limits refer to the maximum winnings a player can withdraw from bonus funds. These limits generally apply to free bonuses and may vary depending on the casino and offer. They act as an essential metric to assess the value for players by illustrating the amount of money players can get their hands on.

Applied to: Can apply to all bonuses but mainly no deposit bonuses

Game Contribution Percentages

Game weighting refers to the contribution of different games towards meeting the wagering requirements of a bonus. Every online casino sets their game weighting scale as they see fit.

Each percentage determines how much of each wager chips away at the wagering requirements of online casino bonuses. Each game contributes differently, with some contributing more than others.

For example, while most slots contribute 100%, most table games are downgraded to as little as 5% or 10%.

Applied to: No Deposit Bonuses, Match Bonuses, Match bonuses With Added Free Spins

RTP Percentages

All non-live casino games have an assigned Return to Player (RTP). This is a percentage indicating the average amount of money that a game will return to players over time.

It matters because it directly affects your probability of winning in a specific game. A higher RTP indicates a greater likelihood of winning, while a lower RTP suggests a lower chance of winning.

How We Grade No Deposit Bonuses

As mentioned above, when we evaluate no deposit bonuses, we look at bonus value, wagering requirements, maximum cash out limits, and game contribution percentages.
