The tracking of poker opponents has become widespread over the past dozen or so years. The legality of poker heads-up-displays (HUDs) has been debated quite frequently during that period. I have played on just about every poker site and used hundreds of different HUDs and can give you a definitive answer.
Are poker HUDs legal? Heads-up-displays, or HUDs, are legal to use on nearly all online poker sites. However, in recent years there is an industry-wide movement toward limiting their use. A poker site’s terms of service will usually disclose its policy regarding HUDs within their website.
The tracking of players via third-party software has had a profound impact on the game since around 2003. I have done quite a bit of research on the subject and will let you know everything you need to know about how HUDs are used and what the pros and cons of them are.
What Is a Poker Hud?
HUD stands for “Heads-Up D
Common Poker HUD Stats
The most common statistics displayed in a poker HUD are:
- VPIP – “Voluntarily Put (Money) In Pot” which shows how often opponents choose to play pots. High frequencies of 40% or higher generally indicate unskilled players.
- PFR – “Pre Flop Raise” which tracks how often an opponent chooses to raise before the flop when they do commit money. This stat is used in tandem with VPIP to make educated guesses on what range of hands an opponent is playing when they raise. Low PFR of under 10 along with a high VPIP usually indicates a weak player.
- AGG% – “Aggression Frequency” is an indicator of how often an opponent makes aggressive actions versus passive ones after the flop. Passive players generally have an aggression frequency of 30% or lower while aggressive players are usually at 40% or higher.
- C-Bet and Fold to C-Bet – These stats tell you how often a player continuation bets and how often they fold to continuation bets after the flop.
There are also literally hundreds of other detailed stats that are usually available to be used in a HUD.
Where Does a Poker HUD Come From?
In order to use a HUD at the poker tables, you are required to have a third party poker tracking software program.
Basically, the software gathers hand histories while you play and processes the information. The data collected is then used in manifesting the heads-up-display on your table.
Who Uses HUDs and Why?
Today, HUD use is widespread in online poker. Even many recreational players, who often have no idea how to effectively use the information, have a heads-up-display on their tables.
However, in the hands of a skilled amateur or professional players, these statistics can be used to profile and pick opponents apart with precision. It’s true that, even though anyone can use a HUD, their prevalence significantly favors the studious.
HUDs have given skilled players the ability to:
- Exploit opponents more efficiently than they otherwise would be able to.
- Find leaks in their own games and take steps to remedy them.
- Play large numbers of tables at the same time without having to follow the action closely.
Ambitious Players Are Forced to Use a HUD
The pervasiveness of HUD-use has given a profound advantage to the players who use them versus those who do not. This fact forces players, who would otherwise eschew the practice, to join the flock.
In short, either you learn to use a HUD (and well) or you are at the mercy of the regular players (regs). People have gotten very good at building HUDs that can pinpoint an opponent’s leaks in subtle yet profound ways.
In fact, it has become almost an arms race as to who can better detect the leaks of the opposition. There is also an entire generation of poker players who are completely lost if forced to play without a HUD.
What Tracking Software Programs Offer HUDs?
The two most often-used software programs that have a HUD feature are Hold’em Manager (HEM) and PokerTracker (PT). While these are still separate software programs, the two companies that created them have merged as of 2014. It is unclear whether one version will be phased out or not.
Both HEM and PT offer advanced HUDs that can tell you, in detail, what another player is doing across multiple streets. However, if you just want basic stats then there is an alternative program called Hold’em Indicator.
How the HUDs look
The Hold’em Indicator HUD (shown on the LT) gives all the basic stats while HEM and PT allow you to fully customize a HUD to tell you whatever you want to know about another player.
How to Make a Poker HUD
Building a customized HUD is actually really easy. Here is a video tutorial I did that will give you some insight into how it’s done.
Even Legal Poker Tracking Software Has Made Winning Tougher
There is actually a lot of irony surrounding “game improvement software” since it actually has made it more difficult to win. The near universal usage of programs that allow deep statistical analysis and HUDs, has created quite a bit of parody among the regs. However, there unintended consequences for this statistical “arms” race.
HUDs Hurt the Poker Economy
It is my opinion that the hyper-analyzation of opponents has led to an unfair playing environment.
There is now a huge gap between so-called good players and the recreational part-time player. Unskilled players go broke quicker so there are less of them playing in the games
Onmany poker sites, it has now come down to being a battle for who can win enough money from the very few unskilled players to eke out a tiny win-rate.
Additionally, almost all recreational players know that “the pros” are using tracking software. They may even view the practice as a form of cheating. This has led to many poker sites increasingly becoming a fish desert as “fun” players leave the games or move to more recreational-friendly poker sites.
No one wins when almost no one can win anymore. Literally.
They Took It a Bit Too Far
I actually think that basic HUD use is good for the game and that everyone should have access to them. As long as the information is something that can be gathered by observant players anyway, there really is no harm in it.
However, the tracking software companies went a bit too far with it.
Being able to analyze exactly what an opponent has done on the river over the past 500,000 hands is a bit ridiculous.
The Advent of Auto-Rate and Badges
There are two features that the major tracking software companies have that allow opponents to be further exploited:
- Auto-Rating is a system of symbols that are assigned to a player based on one or more key statistics that allow them to be pigeonholed based on their tendencies. This allows a player to form separate strategies for attacking the various groupings of players they choose to categorize. Phil Hellmuth has been known to categorize players. There was also a famous 2+2 post about the subject in 2003.
- NoteCaddy Badges are summarized automatic notes based on often deep statistical calculations. They allow a player to instantly recognize when an opponent is playing unbalanced or unprofitably in specific situations. The bigger the hand sample you have on an opponent, the more accurate the badges become.
The good news is that most badges take a huge database of hands to become useful. The bad news is that huge databases can be obtained unfairly.
Data-mining Was the Death Knell
You are supposed to only be able to have stats that you could have collected through your own observation. However, there are online businesses that collect and sell hand histories to anyone willing to buy them.
While this is universally forbidden by all major poker sites, it has not stopped unscrupulous players from partaking in the practice.
The result of data-mining is that hardcore players can have tens of thousands of hand histories on players they have not even played a single hand with. Unsuspecting players are picked apart as a result.
It is worth mentioning that cash game players are not the only ones who have to worry about being unfairly targeted by bad actors. A tracking site designed for sit n’ go players has also been around for years.
Sharkscope allows you to see detailed won/loss histories from opponents and now even offers a HUD with stats similar to those found on HEM and PT. Once again, these stats are unfairly obtained and outlawed by most poker stats. Unfortunately, that does not stop players from still using them.
Why Some Poker Sites Don’t Limit Hud Use
If HUDs truly hurt a poker economy and, in turn, a poker site’s viability, then why are they not being banned by every site? The reason is two-fold:
- Multi-tabling players who play 6,
10,or even 24 tables would get lost very quickly without a HUD. They rely on the information provided by the HUD to make fast decisions. Sites are afraid of losing these loyal customers who simply cannot live without their HUD.
- These high-volume players also generate a lot of rake and poker sites hesitate to limit them in any way.
The Recent Movement Away from Allowing Huds
While some poker sites have chosen to ignore the problem of a failing poker economy, some have embraced a new way of protecting players.
The Recreational Model
There is a whole new generation of poker sites that have taken steps to create a safer environment for players. There are a few basic ways they have done this:
- Anonymous games have made it impossible for players to be tracked over the long term. While a session HUD is often still possible on anonymous poker sites, usually through Hold’em Indicator or a hand history converter.
- Quick Seating is a feature that populates tables automatically without players having to choose a table to play on. This limits the ability of strong players to seek out and target recreational opponents. The effect is a more balanced environment that generally mixes in equal amounts of strong, medium, and weak players on a table. This makes the bad players lose money at a slower rate.
- Limited Hand Histories is an option employed by recreational sites, such as Global Poker, to keep the games non-anonymous while still disallowing HUDs. However, this method has proved to be not nearly as effective as going anonymous is. I have seen reports of players finding ways to have HUDs on their tables regardless.
- Smaller Player Rewards such as giving no
rakebacknor lucrative VIP system deter the pros from even coming to the poker site in the first place. Fewer sharks mean a more stable poker economy overall where the money is not just rapidly ascending to the top of the food chain.
The Proof Is in the Win-Rate
I have played on two of the major recreational poker sites and have to say that it makes a huge difference in my win-rate.
Here is a recent sample played on two disparate poker sites.
- The first screenshot is from America’s Cardroom, a well-known traditional poker site that still allows full HUD use. I was able to win, but my win-rate was not that impressive (only 3.42bb/100) over the fairly small sample size.
- The second screenshot is from Ignition Poker, a popular recreational site that has anonymous games.
In the samples, I was testing some of my poker charts that I have been working on for years and not playing my A game by any stretch of the imagination. However, I was able to pretty much crush it (for 8.62bb/10) on Ignition across all stakes. On ACR, it was hard to even beat the micro-stakes.
List of Recreational Poker Sites
If you are looking for a place to play where you don’t have to worry as much about other players knowing every little aspect of how you play, I recommend trying the sites listed below.
Sites Who Have Limited HUD Use
|After 24 hrs
For US players I recommend Ignition Poker. For anyone else in the world, Unibet is a really good option.
List of Traditional Poker Sites
If you love to dive deeply into stats and don’t mind other players doing the same, there here is a list of sites you will want to try.
Sites with Unlimited HUD Use
|Black Chip Poker
If you want a balance between soft games and full HUD use, I recommend BetOnline or Sportsbetting Poker (same network). You will have to use a card catcher to get hand histories, but it is well worth the small expense.
History of Poker HUDs
While PokerTracker was originally released in 2001, it wasn’t until 2003 until the real game-changing moment happened.
When PokerTracker 2 came out, something called the “PokerAce” HUD was added as the first commercially viable HUD.
The “Golden” Age of HUD Use
For the next few years, there was a lack of awareness about this software in the general public. All the while, serious players are pros were raking in the big bucks by having a huge informational edge on their opponents.
However, in 2006 Hold’em Indicator was released. It had a much more user-friendly feel to it and included a helpful odds calculator built into the software. The rudimentary HUD came as a feature and help level the playing field a bit.
In 2007, Hold’em Manager came out and took things even further. Even more detailed stats emerged and eventually, more advanced ways of tracking players were added. With auto-rating and then Notecaddy, poker geeks were in hog-heaven. Table selection and finding weak players became really easy.
Today, it looks like the writing on the wall that tracking software and HUD-use in it’s current form is in decline. No major released or updates have come out in several years.
My advice to them is to go the route that Javaro has and simplify things and work directly with sites to comply with the changing poker environment. I think they should keep the deep statistical analysis for players to do on their own games but limit and discourage the unethical exploitation of weaker opponents.
The first 15 or so years of the online poker era have been a wild ride. The development of player tracking tools has heavily influenced how poker sites currently operate.
As with anything, there is an ongoing dialectic on what the experience of poker players should look like. Right now we are trending toward finding balance and more enjoyment for all players.
I am hoping this attitude brings more players into the game and the viability of online poker lasts indefinitely.

How can I track my statistics as a live player?
What is VPIP and PFR? VPIP and PFR are the two most common stats that players have in their Heads-Up-Display or HUD. VPIP means “Voluntarily Put In Pot” and PFR means “Pre-FlopRaise.”
What is an average continuation bet percentage? Continuation bet percentages typically fall between 40% and 90%. However, the average of all players in my Hold’em Manager database is 59.6%.
