Sharkscope Ability Rating Explained: What Is a Good Sharkscope Rating?

Poker is a game of information, and understanding your opponent's Sharkscope Ability Rating is one of the fastest ways to gain a competitive edge. The more data you have on the players at your table, the higher your chances of beating them.

With thousands of players grinding online tournaments daily, it’s impossible to remember every regular or identify every recreational player based on memory alone.

This is where Sharkscope comes in. The platform collects publicly available tournament results and organizes them into long-term performance statistics that players can use for analysis.

In this guide, we will explain exactly how the Sharkscope Ability Rating works, what is considered a good score, and how you can use this online tool to exploit your opponents' weaknesses.

What Is Sharkscope?

Ever since poker found its place in the online world, poker players have been trying to find ways in which they can gather as much information about their opponents as possible.

Over the years, many tools for tracking players' information and data were developed, but the one that stands out, at least when it comes to information regarding multi-table tournaments or MTTs, is Sharkscope.

Sharkscope is one of the biggest poker databases in the world. The SharkScope database collects data from millions of games, providing valuable statistics about players' performances. It contains almost 20 years of data about poker players and their online poker tournament results.

The site covers information from dozens of online poker sites, which makes it one of the most trustworthy poker tools available.

It contains data about MTT and SNG (Sit & Go) tournaments from active and even some closed online poker rooms, including GGPoker, PartyPoker, Pokerstars, Winamax, BTMGM, ACR, and Global Poker.

What Is Sharkscope Used For?

Poker players use Sharkscope to find out more information about their opponents, their winnings, and their skill levels.

For example, let us say that you recently registered on a new poker site and you are playing in a tournament against players which you have absolutely no information about.

You don’t know if they are professionals or amateurs, how good they are, or are they regularly playing tournaments with similar buy-ins.

To find out more information about your opponents, you just need to:

1. Visit the Sharkscope website
2. Enter the player name (nickname or username) of each of your opponents in the search bar on the Sharkscope website to access their poker stats and tournament results
3. Select “Quick Search” or “Advanced Search”

If you select the quick search, Sharkscope will display a summary of the results for the username you entered. If you select the advanced search option, the site will offer additional filters that you can use to filter out the player’s results.

Some of the information that Sharkscope will show include:

• Profit history
• Number of games (tournaments)
• Average profit per game
• Average stake
• Average ROI
• Total profit
• Ability
• Form

Note: Sharkscope gives five free searches per day, and the results for these searches come with limited information. Additional searches and more detailed results come with paid subscriptions to their website.

How to Use Sharkscope to Gain An Advantage Over Your Opponents

While Sharkscope is available to everyone, not all players use this software in the most optimal way. So, we decided to create a guide on how to use the Sharkscope poker website in the most efficient way possible.

Sharkscope statistics give you context behind a player’s long-term results. By reviewing metrics such as tournament volume, ROI, and average buy-in, you can better understand the level of competition they typically face and how experienced they are in multi-table tournaments.

First, we need to set a solid foundation when it comes to each individual piece of information you can get from the website. The data is available based on the subscription plan

Sharkscope – Player Profit History

In this category, Sharkscope shows the player's win/loss history under a specific username. Depending on the sample size, and if the player is using the same username across different poker sites, this data can tell you if the player is an overall winner in MTTS and SNGs.

It also shows how much money the player won or lost on a specific poker site and if he became better over time.

For example, someone can go from a losing to a winning player over the course of his poker career, and this graphic will show you when he started winning.

By right-clicking on this graphic, you can also open additional options such as:

• Graphs
• Tournaments
• Breakdown
• Statistics
• Leaderboards
• Insights

Each of these options has additional filters that allow you to break down the game of your opponent even more. Explaining each of the filters would take too much space, so we will give you one example of how you can use them.

If a player's profit history shows that he has won money in the game or is maybe a breakeven player, you can use the graphs and tournaments filter to check if most of his winnings come from one or a small number of tournaments.

One big win can drastically impact players winning in tournaments especially if he won or had a deep run in a tournament above his average buy-in (for example he qualified through a satellite). This can also show you that he is probably losing money in his regular games.

Sharkscope – Game Count

The count graphics shows how many games (Tournaments or MTTs) a player has played in his lifetime on a specific poker site.

This data can help you tell apart professional poker players from the amateur ones, but you will have to combine it with additional information from other graphics (such as the Profit History > Tournaments > Oldest) to get a better idea of the player's volume.

Some players might have a lot of games, but over a long period of time, while others might have a smaller amount but over a shorter period.

For example, if a player has a winning history and a large number of games, these two indicators can help you figure out that he is a consistent winner in MTTs and SNGs.

Sharkscope – Average Profit, Average Stake, and ROI

You can use the average profit and the average stake graphics to determine which buy-ins the player play for the most part.

These two graphics are best used with the ROI column for the following reason:

For example, let's say that two players have a similar number of games over the same period:

• Player A’s average buy-in is $15 and his ROI in these games is 9%.
• Player B’s average buy-in is $100 and his ROI in these games is 5%.

If you only compare the ROIs of these two players, you will come to the conclusion that Player A is a better player than Player B because he has a higher ROI.

However, if you also look at the average buy-in, you will understand that Player B is winning in bigger games, which makes him a more successful player.

Sharkscope – Profit Column

The profit column is not as useful by itself, as it only shows the total winning or losses of a player on a specific poker site.

Sharkscope – Useful Filters

Apart from the obvious graphics, Sharkscope offers advanced filters that will help you break down the paying style of your opponents even further.

If you select the “advanced search options” and type in the name of the player you will get the following filters:

• Site filter – shows results based on the poker site
• Game filter – shows results based on game type (SNGs or MTTs)
• Entrants – shows results based on the number of participants
• Stake – shows results based on the buy-in range
• Include tournament types – shows results based on the tournament type (includes additional filters such as table size, structure, speed, payout structure, game format, etc.)
• Exclude tournament types – excludes results based on the tournament type (includes additional filters such as table size, structure, speed, payout structure, game format, etc.)
• Date range – shows results for a specific set period

Sharkscope HUD and Features

The Sharkscope HUD (Heads-Up Display) is designed to display key tournament statistics directly at your table while you are playing online poker.

Instead of manually searching for a player’s profile on the Sharkscope website, the HUD overlays relevant data next to each opponent. This allows you to quickly assess their experience level and overall results without interrupting your session.

Some of the main statistics displayed through the HUD include:

• Ability Rating
• Average buy-in
• Total profit
• ROI
• Number of tournaments played

This information can be especially useful in large-field MTTs where you encounter unfamiliar opponents frequently.

For example, if you notice that a player has:

• A high average buy-in
• Strong long-term ROI
• A large tournament sample

You can reasonably assume that you are facing an experienced regular rather than a recreational player.

On the other hand, a low sample size combined with a low average stake often indicates a newer or more casual competitor.

Important Considerations

Before using the Sharkscope HUD, always check the rules of the poker site you are playing on. Some platforms restrict or regulate the use of third-party tools.

Additionally, keep in mind that statistics should support your decisions – not replace sound poker fundamentals. A strong player can run poorly over a small sample, and a weaker player can temporarily appear profitable due to variance.

The HUD is most effective when used as a quick reference tool, helping you categorize opponents faster and adjust your strategy accordingly.

Sharkscope Ability Rating Explained

You probably noticed that we didn’t mention the “Ability” column when we were talking about some of the features available in the summarized view of the player's profile.

It is because we wanted to explain it separately, as it is one of the more “controversial” pieces of information you can find on the site.

However, players' ability ratings can be a very useful tool once you understand how to interpret them.

On the Sharkscope website, you can find the following information regarding the Sharkscope Ability Rating:

“The Ability rating is a rating that goes up to 100 and shows a player's ability based on an assessment of all the other statistics we have compiled for that player.”

As you can see, the definition of the data in this column is pretty vague and leaves many open questions. We did our best to try and find additional information that could be useful and help you use this data more effectively.

The first thing to note is that, although the rating goes up to 100, it does not start from 1, as one might assume; instead, it starts from 50. meaning that all players have a rating higher than 50 and that the actual range for this data is from 50 to 100, not from 1 to 100.

For example, even if a player has been constantly losing money over a large sample, his ability will be at least 50.

The thing that confuses most people is when they compare one player with a small sample size against a player with a larger sample or two players with a smaller number of games.

In these situations, the results shown in the player's ability column can be interpreted as “odd.” This is because the site’s algorithm does not have enough data to accurately assess the player's ability.

How to Use the Ability Rating Accurately

With this said, Sharkscope’s Player Ability Rating is most accurate and best used when comparing players with a decent amount of recorded volume but playing different stake levels and tournament types.

For example, if we take two players with many tracked tournaments, but play different games.

• Player A is a small loser at high-stakes games.
• Player B is a small winner at micro-stakes games.

In this case, the Player Ability Rating of Player A will be higher than the Player Ability Rating of Player B.

If you are in a rush, you can also make assumptions about the player based on the Sharkscope Ability rating alone. The way we judge it:

• 50-60 – losing recreational player
• 61-70 – mediocre player or low-stakes regular still trying to learn
• 71-80 – strong regular likely beating the games up to mid stakes
• 81-90 – a very solid player who is a winner in his games
• 90+ – a top pro who is crushing tournaments left and right

Examples like this are where the Player Ability Rating is very useful and can help players make quick assessments of their opponents without having to spend hours using different filters to determine their skill level.

Summary

Sharkscope is one of the most powerful tools you can use when playing online tournaments, and it can even come in handy in a live setting, provided you know players’ online handles. It can help you gauge who the good players at your table are.

While it will cost you some money to gain full access to everything Sharkscope has to offer, the wealth of information you’ll gain access to by doing so will make it well worth your while!

Frequently Asked Questions About Sharkscope Ratings

My relationship with cards started thanks to my father. I was still in elementary school when he first taught me how to play Rummy, and I still remember the long evenings spent playing cards with my family. During the poker boom I was still underage, but the televised tournaments immediately captured my attention. I became fascinated with the game and started learning different poker formats whenever I had the chance. Later in life, as an adult, I was fortunate enough to spend four years playing poker professionally. During that time I mainly focused on Heads-Up Sit & Go games, where I found the format that suited me best. Even though my professional career was relatively short, poker remains something I’m grateful to have experienced as a major part of my life. Today I play mostly as a hobby, while writing has become my main focus. That said, my enthusiasm for writing about poker is just as strong as my passion for playing the game once was.
