What Are Loose Slots?
In slot player terminology, a 'loose' slot is one that returns a higher percentage of all wagers to players over time. The opposite is a 'tight' slot. The key measure is return to player (RTP), which is the theoretical long-run average of money returned to players. For example, an RTP of 96% means that, over millions of spins, the machine is expected to pay back €96 for every €100 wagered. It does not mean you will get €96 back from a €100 session: individual sessions can vary wildly.
The term gained popularity in land-based casinos, where regulators sometimes require casinos to publicly report their 'hold percentage': the portion of wagers kept by the casino. Publications like Casino Player and Strictly Slots flipped those numbers into payback percentages and began publishing annual 'Loosest Slots' awards. As the Casino Player loosest slot awards explain, these awards are based on actual historical statistics, not theoretical simulations.
How RTP Works and Why It Matters
RTP is calculated over the entire lifecycle of a slot machine, often millions of spins. It is a theoretical average, not a promise for any single player or session. A slot with 97% RTP can still produce long losing streaks, and a slot with 92% RTP can produce a big win. The difference between loose and tight slots is most noticeable over very large numbers of spins.
Online slots typically publish their RTP in the game rules or help screen. Land-based slots in regulated markets may have their payback percentages reported to regulators and published periodically. Players in Ireland should rely on the RTP published by game developers within the game itself. RTP Explained guide
Certified Loose Slots Programs
Some casinos seek third-party verification of their slot paybacks. The Strictly Slots Loose Slots certification is one example. According to Casino Player's annual Loosest Slots survey, Rocky Mountain Gaming received the Strictly Slots Loose Slots certification for its Cripple Creek, Colorado casinos. Such certifications are based on publicly reported hold/payback statistics and apply only to the specific casino and jurisdiction involved. 7 Clans Casinos' announcement
Such certifications are specific to the casino and jurisdiction. They do not apply to online casinos in Ireland. Players should treat any 'loosest slots' claim without independent verification with caution.
Where to Find Loose Slots Data
For land-based casinos in the United States, publications like Casino Player and Strictly Slots publish annual loosest slot awards based on publicly reported hold/payback statistics. The 2025 awards note that not all casinos are included because reporting requirements vary. For example, Illinois stopped publicly reporting slot percentages, so its casinos are no longer included.
For online slots, the best source is the game's own information screen, which typically states the RTP. Reputable developers publish RTP consistently across their game portfolios. Our slot provider guides list typical RTP ranges for major studios, but always check the specific game you are playing.
Loose Slots in Ireland: What to Expect
In Ireland, online slots are available from licensed operators, and RTP is generally published within the game. There is no public database of online slot RTPs in Ireland, so players cannot compare casinos on that basis alone. Land-based slots in Irish casinos and arcades are not subject to public payback reporting either.
Irish players looking for higher RTP should focus on games with published RTP above 96%, which is often considered a loose slot. However, RTP is only one factor; volatility and hit frequency also affect the playing experience. See our volatility guide for more.
Common Myths About Loose Slots
Myth: A slot is 'due' for a win because it has been tight. Slots use random number generators (RNGs) that operate independently of past results. Each spin is random, and past outcomes do not influence future ones. See our RNG guide.
The number of paylines or ways to win does not determine a slot's RTP. RTP is determined by the game's math model, including the paytable and bonus features, not by the number of ways to win.
In regulated markets, slot RTPs are typically set by the game developer and are not changed at will by the casino. Online slots have fixed RTPs that are determined by the game's math model.
How to Choose a Loose Slot
If you want to prioritise higher RTP, follow these steps:
- Check the game's help screen or information panel for the published RTP. This is usually found in the game rules or paytable.
- Compare RTP across similar games. A difference of 1–2% may not seem large, but over many spins it can affect your expected losses.
- Consider volatility. A high-RTP, high-volatility slot may still drain your bankroll quickly if you hit a cold streak. Low-volatility slots with decent RTP can stretch your playtime.
- Use our best online slots Ireland page to find games with published RTP and provider details.
- Remember that RTP is a long-term average. No slot can guarantee a win, and no strategy can change the odds.
Responsible Gambling
Chasing losses on the hunt for a loose slot is a common pitfall. Set a budget before you play, stick to it, and treat slots as entertainment, not a way to make money. If you need support, see our responsible gambling resources.
Loosest Slots FAQs
What is a loose slot?
A loose slot is a slot machine with a higher return to player (RTP) than average. For example, a slot with 97% RTP is looser than one with 94%. The term is relative and does not guarantee wins.
Which casino has the loosest slots?
In the US, the 2025 Loosest Slots Awards named Nassau OTB at Resorts World New York City as having the loosest slots, with a 96.94% return. In Ireland, there is no equivalent public ranking for online or land-based slots.
Are online slots looser than land-based slots?
Online slots often publish RTPs in the mid-to-high 90s, while land-based slots typically have lower published payback percentages. However, direct comparisons are difficult because land-based payback percentages are not always publicly reported and can vary by jurisdiction and denomination.
Can I find loose slots in Ireland?
Irish players can look for online slots with published RTP above 96%. There is no public database of land-based slot paybacks in Ireland, so online games with transparent RTP are the most accessible option.
Do loose slots pay out more often?
Not necessarily. RTP is about the long-term average return, not hit frequency. A loose slot may have fewer but larger wins, or more frequent smaller wins. Volatility determines the pattern of wins.
How can I tell if a slot is loose?
Check the game's help screen for the published RTP. If it is above 96%, it is generally considered loose. For land-based slots, look for casinos that participate in certified loose slots programs.
Is there a strategy to win on loose slots?
No. Slots are random, and no strategy can change the odds. RTP is a theoretical average, and outcomes are determined by a random number generator. Always play within your budget.
