Slot Tracker is a community-driven tool that logs the spins you play at UK online casinos and turns them into hard numbers: return to player (RTP), SRP, hit rate, volatility, bonus frequency and your running profit and loss. More than 11,000 players use it, and together they have fed over 68 million spins on more than 3,700 slots into its database. Below we explain what each statistic means, how to install the software, what you will find in the console and how to read the results without reading too much into them.
What Slot Tracker measures on every spin
Slot Tracker measures five headline metrics for each game, combining your own sessions with data pooled from the wider community. Each one answers a different question about how a slot behaves in real play.
| Metric | What it tells you | Based on |
|---|---|---|
| RTP | Share of total stakes paid back as wins | Community spins, not theoretical maths |
| SRP | Money in and money out, expressed per spin | Each spin, independent of bet size |
| Volatility | Whether a slot leans low, medium or high | Tracked spins on that slot |
| Hit rate | How often a spin produces a win | Wins relative to spins tracked |
| Best win | Largest payout recorded on the slot | Highest result logged to date |
These figures are available for well-known titles such as Starburst and Money Cart 2 as well as hundreds of less familiar games, so you can check a slot before committing to a long session. If any of the terms are new to you, our casino glossary explains them in plain English.
Community RTP versus the published figure
Community RTP is the return measured on real tracked spins, while a provider’s published RTP is a theoretical long-run average. Both numbers are useful, but they answer different questions.
The published figure assumes an enormous number of spins, far more than any single player will ever see. Slot Tracker’s version instead adds up what users have actually staked and won. When a slot has millions of tracked spins behind it, the community figure tends to settle close to the theoretical one; when only a few thousand spins have been recorded, a single big bonus round can push it well above or below.
SRP adds a second angle. Because it looks at the money moving in and out of a slot on a per-spin basis, it is not skewed by players who bet large amounts, which makes comparisons between high-stakes and low-stakes sessions fairer.
Hit rate then tells you how frequently wins land, and it is often the figure that shapes how a session feels. A slot can return a respectable RTP while landing wins only rarely, which means long dry spells broken up by occasional larger payouts. That pattern is typical of high volatility slots.

How the extension, console and widget fit together
Slot Tracker runs on three linked parts: an extension that captures spins, a console that analyses them and a widget that displays live data.
| Component | Role | Where you access it |
|---|---|---|
| Extension | Connects the slots you play to your personal record | Chrome Web Store, Google Play or the official site |
| Console | Stores your activity and compares it with the community | Dashboard on the website or the extension button |
| Widget | Shows live Slot Tracker data on casino review sites | Embedded on third-party review pages |
The Slot Tracker extension does the quiet work in the background. Once it is installed and you are logged in, it passes the outcome of each spin to the console, so there is no manual note-taking and no spreadsheet to keep up to date. The widget is purely a display tool: review sites that embed it can show visitors current community data, but logging your own sessions still requires the extension and an account.
How to download Slot Tracker and get started
You can download Slot Tracker and have it running on a PC in less than five minutes. The official website hosts a step-by-step walkthrough, but the process comes down to four actions:
- Get the Slot Tracker extension from the Chrome Web Store, or download it manually from the official Slot Tracker site.
- Enable it in Chrome’s extensions menu so it runs while you play.
- Log in to Slot Tracker.
- Press “Launch Console” to open your personal statistics.
If you would rather use an Android device, the app is also listed on the Google Play Store. From that point you simply play slots at your usual casino, and the data builds up session by session whichever operator you choose.
Inside the Slot Tracker console
The Slot Tracker console is split into five sections, which you can open from the website dashboard or straight from the extension button. Each section offers a personal view alongside a community comparison.
Dashboard
The Dashboard is your at-a-glance summary. It lists the providers, casinos and slots that have paid you best, with slots ranked by average RTP and by overall profit. Lower down you will find your activity totals for bets, wins and P&L, together with bonus statistics: total bonuses, average bonus and bonus frequency. Community benchmarks for total spins, total bonuses and RTP sit alongside, so you can see immediately whether your results are running above or below the crowd.
Slots
The Slots tab lists every game you have played, divided into personal and community views that can be sorted by RTP or best win. Open any title to check how many spins it has, the money staked versus returned, its RTP and P&L, win and bonus details, and a volatility index, each shown for you and for the wider user base.
Casinos
The Casinos tab presents each operator as a card showing RTP, profit and loss, total spins and best wins, again split between personal and community figures. Every casino also comes with its own expense log, which makes it easy to see where your money has gone. To compare operators by their overall payout record, visit our best payout casinos page.
Providers
The Providers tab uses the same card layout for game studios such as NetEnt and Play’n GO, among many others. It helps you spot whether a particular studio’s games have treated you better or worse than the community average. Our game providers hub profiles the studios themselves.
Activity
The Activity tab is a day-by-day expense log showing which slots you played and how much you won or lost. It is the simplest place to check whether your spending matches the budget you set yourself.
Practical ways to use your slot statistics
Slot Tracker data is most useful for planning which slot to play, which casino to use and how your sessions compare. Typical uses include:
- Finding high RTP slots from community results within seconds.
- Following your profit and loss spin by spin across several casino sites in one place.
- Choosing a game whose volatility and hit rate suit the way you like to play.
- Comparing community data across different slots to pick out the strongest payers.
- Checking your own slot statistics against the community averages shown at the bottom of the dashboard.
None of these uses involves predicting the next spin. They simply replace guesswork and vague memories of “that slot always pays” with recorded numbers, which leads to better-informed decisions about where to spend your time and money.
Reading the numbers responsibly
Slot Tracker statistics describe past spins, so they cannot forecast future results or tilt the odds in your favour. Every spin on a licensed slot is decided independently by a random number generator, whatever happened on the previous one.
Keep three points in mind when you look at the data:
- Sample size matters: figures built on millions of spins are far steadier than those based on a few hundred.
- Your personal RTP will swing much more than the community figure, simply because you have played fewer spins.
- A slot showing a high community RTP right now is not “due” to keep paying.
The most valuable part of the tool may be the least exciting one. A clear record of what you have staked and lost, day by day and casino by casino, is a practical way to keep gambling within limits you are comfortable with, and it pairs well with the deposit limits and time-outs available in casino account settings.

Frequently asked questions
How does a slot tracker collect its data?
A slot tracker collects data by logging the result of each spin you play and turning those results into statistics. With Slot Tracker, the browser extension passes every bet and win to the console automatically, where RTP, SRP, hit rate, bonus frequency and profit and loss are calculated. Your spins are also pooled with other users’ data to produce community figures for each slot.
Does Slot Tracker work on mobile devices?
Yes, Slot Tracker is available on Google Play for Android devices, alongside the Chrome extension for desktop browsers. On a PC, setup takes less than five minutes: enable the extension in Chrome, log in and press Launch Console. A manual download of the extension is also offered on the official Slot Tracker website, which includes a step-by-step setup walkthrough.
Is community RTP a guarantee of future payouts?
No, community RTP describes what has already happened on the spins users have tracked, not what the next spin will pay. Every spin is independent, and a slot with only a small tracked sample can show an RTP far above or below its long-run figure. Treat the number as context for choosing a game, alongside the provider’s published RTP and your own budget.
How do RTP and SRP differ when comparing slot sessions?
RTP is the share of stakes paid back as wins, while SRP tracks money in and out of a slot per spin. Because SRP works on a per-spin basis, it is unaffected by bet size, so sessions played at high and low stakes can be compared on equal terms. Slot Tracker also calculates RTP from community spins rather than from the provider’s theoretical model, which makes it a measure of real results.
Can Slot Tracker show my profit and loss at each casino?
Yes, the Casinos tab gives every operator its own card showing RTP, profit and loss, total spins and best win. Each figure is shown for you and for the community, and every casino has its own expense log. The Activity tab adds a day-by-day record of the slots you played and how much you won or lost across all the sites you use.
How many spins has Slot Tracker recorded so far?
Slot Tracker has logged more than 68 million spins across over 3,700 slots, and more than 11,000 players use it. These totals keep rising as the community plays, so treat them as a snapshot rather than a fixed figure. The more spins recorded on an individual slot, the more meaningful its community RTP and hit rate become, because small samples swing heavily.
Can casino review sites display live tracker data?
Yes, the Slot Tracker widget embeds live tracker data on casino review websites, so readers see community statistics next to a review. The widget is a display tool rather than a recorder of your own play. To log your sessions and see personal profit and loss, bonus frequency or RTP, you still need the extension and the console.
