You’ve probably heard the advice: “Always check the RTP before you spin.” It sounds solid, but then you load up a game like Blood Suckers or Starburst, stare at the screen, and realize you have no clue where to look. The button is rarely labeled “RTP.” Instead, it’s hiding inside paytables, buried in rules menus, or disguised as a question mark. And if you’re playing in a land-based casino in Las Vegas or Atlantic City? Good luck finding that info printed on the cabinet. Let’s cut through the confusion so you know exactly where to find the numbers that actually matter.
Checking the Info Screen in Online Slots
When you’re playing at regulated US casinos like BetMGM, DraftKings Casino, or FanDuel Casino, the RTP is almost always available—it just takes a few taps to find it. Most modern video slots follow a standard design pattern. Look for a small icon, usually a “i,” a question mark, or a gear icon, typically located in the bottom corner of the game interface. Tapping this opens the game rules or paytable.
Once inside, you might need to swipe through a few pages. Developers like NetEnt or IGT often list the return percentage on the first page of the paytable. Others, particularly games from studios like Pragmatic Play, might hide it at the very bottom of a multi-page rules document. You are looking for a specific line of text that reads something like “The theoretical return to player is 96.4%.” If you see a range, like “RTP ranges from 88% to 96%,” that’s a signal the operator may have selected a lower setting.
Why Some Games Show RTP Ranges
This is where things get tricky. You might search for the RTP on a slot like Big Bass Bonanza and find a confusing chart showing multiple percentages. This is because many game suppliers now offer “flexible RTP.” They provide the casino with options—often 94%, 92%, or even 86%—and the casino chooses which version to host.
Higher RTP versions are better for your bankroll, obviously. A 96% RTP means the house edge is 4%. Drop that to 94%, and the house edge jumps to 6%. That 2% difference compounds over thousands of spins. If you are playing at premium operators like Caesars Palace Online or Borgata, they typically host the higher settings to remain competitive. Less reputable offshore sites often select the lowest possible RTP to maximize their profit. If the info screen shows a range, assume the worst unless the specific number is clearly highlighted.
Hidden Settings in High Volatility Games
High volatility games, which are popular for their massive potential jackpots, often obscure their RTP further behind “bonus buy” features. If you are playing a slot where you can pay to trigger a bonus round, check if buying the bonus changes the RTP. In many Megaways slots, buying the feature actually increases the RTP slightly—for instance, jumping from 96.0% to 96.5%—because you are removing the base game grind. This information is always found in the help files associated with the specific bonus mechanic.
Finding RTP Information for Land-Based Slots
If you are walking the casino floor in Vegas, finding the RTP is a different beast. Physical slot machines do not have a convenient “i” button. The information is technically public, but you have to work for it. In Nevada, the Gaming Control Board requires casinos to hold a specific payout percentage, but individual machines aren't labeled.
Your best bet is to look for the denomination. Generally, higher denomination slots offer better returns. Penny slots on the Strip often run as low as 88% RTP, designed to grind down small bets slowly. Move up to $1 or $5 slots, and the return can climb to 94% or 95%. Some specific land-based titles, like certain IGT or Aristocrat cabinets, might list the payback percentage on the glass covering the reels, but this is rare. For US players, the rule of thumb is simple: the fancier the casino, the tighter the penny slots often are. Downtown Vegas or local “locals” casinos generally offer better payback percentages than the mega-resorts on the Strip.
Third-Party Resources and Slot Databases
Sometimes the game doesn't make the number easy to find, or you want to research before you deposit. In these cases, independent slot tracking sites and review databases are your friend. Websites like SlotCatalog or specialized forums have massive databases where players submit the theoretical RTP for thousands of titles.
This is particularly useful for checking if a US casino has adjusted the settings. For example, if you know White Rabbit Megaways should have an RTP of 97.77%, but you find a version online running at 94.5%, you know the operator has opted for the lower tier. Keep in mind that progressive jackpot slots operate differently. They usually have a lower base RTP (often 88-92%) because a portion of every bet feeds the jackpot pool. The “true” RTP on these games can technically exceed 100% if the jackpot gets high enough, though hitting it is statistically unlikely.
Comparing Slot Types and Their Typical RTP
Not all slot categories are created equal. Knowing the general benchmarks helps you spot a bad game instantly without even checking the help file.
| Slot Type | Typical RTP Range | Volatility Level |
|---|---|---|
| Classic Slots (3-reel) | 93% - 95% | Low to Medium |
| Modern Video Slots (5-reel) | 94% - 96% | Medium to High |
| Progressive Jackpots | 88% - 94% | Very High |
| Branded Slots (Movies/Music) | 90% - 95% | Varies |
Branded slots—games based on movies, TV shows, or bands—often carry lower RTPs. The developer has to pay licensing fees for the intellectual property, and they recoup that cost by tightening the game’s payout math. If you are playing a slot based on a blockbuster movie, don't be surprised to see an RTP hovering around 94%.
FAQ
Do all slot machines have the same RTP?
No, and assuming they do is a quick way to lose money faster. RTP varies wildly between games. You can find high-payout slots like Mega Joker (99% RTP) and tight slots sitting at 85%. Even the exact same game title can have different RTP settings depending on which online casino is hosting it.
Is higher RTP always better?
Usually, but not always. A 97% RTP slot with extreme volatility might drain your bankroll faster than a 94% low-volatility slot. High RTP just means the math is theoretically better over millions of spins; it doesn't guarantee you will win in a single session. You still need to consider how often the game pays out (hit frequency) and how big the wins are.
Does the RTP change when I play with bonus money?
The game’s mechanics don't change, but the effective value does. If you are playing with a casino bonus that has a high wagering requirement (like 30x), a lower RTP slot makes it mathematically much harder to clear that bonus. High RTP slots are generally preferred for bonus clearing to preserve your bankroll while you grind through the playthrough requirements.
Do casinos change RTP during the day?
At licensed US casinos (New Jersey, Pennsylvania, Michigan, etc.), this is illegal. The game is tested and certified by state gaming labs to ensure the RTP matches what is advertised. Unregulated offshore casinos are a different story; they can technically adjust settings, which is why sticking to regulated brands like DraftKings or BetRivers is essential for fair play.
