Quick answer: official Nevada Gaming Control Board figures for the 12 months to August 2026 show the loosest slots in the Las Vegas area are in the locals casinos of the Boulder Strip, which kept 6.55% of money played (about 93.5% paid back). The Strip kept 7.75%, and Downtown was the tightest area at 8.36%. Outside Las Vegas, Reno’s Washoe County paid back the most (5.67% kept). Within any area, $1 and higher machines generally pay back more than penny slots. No official data names a single loosest casino.
Loosest slots in Las Vegas and Nevada by area
Every month the Nevada Gaming Control Board (NGCB) publishes how much casinos in each area won from their slot machines, as a percentage of the money played. The lower that “win percentage”, the looser the slots. Payback is simply 100% minus the win percentage. Here are the areas from loosest to tightest:
| Area | Slot win % (12 months to Aug 2026) | Payback | Calendar year 2025 win % |
|---|---|---|---|
| Washoe County (Reno area) | 5.67% | 94.33% | about 5.5% (Reno area) |
| Elko County | 5.84% | 94.16% | – |
| Boulder Strip (locals casinos) | 6.55% | 93.45% | about 6.4–6.5% |
| Mesquite | 6.73% | 93.27% | – |
| Nevada statewide | 7.14% | 92.86% | 7.13% |
| Clark County (all) | 7.42% | 92.58% | – |
| North Las Vegas | 7.63% | 92.37% | about 7.5% |
| Las Vegas Strip | 7.75% | 92.25% | 7.83% |
| Laughlin | 8.27% | 91.73% | – |
| Downtown Las Vegas | 8.36% | 91.64% | 8.30% |
The pattern has held for years. Reno has had the lowest slot hold of any reporting area since 2004 (an average of 5.21%), and the Strip’s long-run average of 7.57% is about 45% higher, according to UNLV research reported by the Las Vegas Review-Journal and Las Vegas Advisor.

Are Downtown slots looser than the Strip?
No, not recently, even though that’s often repeated. Downtown casinos kept 8.36% of slot play in the 12 months to August 2026, against 7.75% on the Strip. It was the same in 2025 (8.30% against 7.83%) and in 2024 (8.47% against 8.03%). If you want looser machines in the Las Vegas area, the off-Strip locals casinos on the Boulder Strip have done better than both.
The NGCB also splits the Strip by casino size. In the 12 months to August 2026, Strip casinos with $12 million to $36 million in yearly gaming revenue kept 6.97% of slot play, the 25 biggest casinos ($72 million and over) kept 7.79%, and the middle group ($36 million to $72 million) kept 8.36%. So the biggest resorts weren’t the tightest.
Which slot denominations pay best in Las Vegas?
Generally, the more each spin costs per credit, the more the machine pays back. Penny slots are the tightest common machines on both the Strip and Downtown. The pattern isn’t perfect, though: on the Strip, quarter machines were even tighter than pennies in 2025.
| Machine | Strip win % | Strip payback | Downtown win % | Downtown payback |
|---|---|---|---|---|
| 1¢ (penny) | 10.79% | 89.21% | 10.95% | 89.05% |
| 5¢ | 7.88% | 92.12% | 5.80% | 94.20% |
| 25¢ | 11.27% | 88.73% | 7.59% | 92.41% |
| $1 | 7.48% | 92.52% | 5.93% | 94.07% |
| $5 | 4.92% | 95.08% | 7.26% | 92.74% |
| $100 | 6.28% | 93.72% | 6.83% | 93.17% |
| Multi-denomination | 7.61% | 92.39% | 8.15% | 91.85% |
| All slots | 7.83% | 92.17% | 8.30% | 91.70% |
The newest figures show the same: on the Strip, $5 machines kept just 4.34% in the 12 months to August 2026 (95.66% paid back), against 10.53% for pennies. Most machines on a modern floor are multi-denomination games, and they sit close to the overall average. Our penny slots guide explains why low-stake games tend to return less.
What the slot win percentage really means
- It’s what casinos actually kept, not what the machines are set to pay. The NGCB divides the slot win by the total amount played, so a big jackpot in one month can move the figure.
- It includes video poker and other machines, not just reel slots.
- It only covers bigger venues. Bars and other small venues with 15 slots or fewer (restricted licensees) aren’t in the report.
- It doesn’t name casinos. The NGCB reports areas and revenue groups, not individual properties, and hides detail where fewer than three casinos report.
- Nevada sets a floor. Under Nevada Gaming Regulation 14, every machine must be designed to pay back at least 75% over time. Real averages are far above that.
Which casino has the loosest slots in Las Vegas?
Nobody can say from official data, because the NGCB doesn’t publish figures for single casinos. Lists that name one casino as “the loosest” are based on reader polls, players’ impressions or undisclosed methods, so we haven’t repeated them. What the data does show is that locals casinos away from the Strip and Downtown, and the northern markets around Reno, have kept the least from slot players.
Tips for finding looser slots in Las Vegas
- Play off the Strip if slots are your main game. The Boulder Strip area kept 6.55% against the Strip’s 7.75% in the latest figures.
- Move up from pennies if your budget allows. $1 machines kept 7.48% on the Strip in 2025, against 10.79% for pennies. Bigger stakes mean faster losses in money terms, so size your bets to your budget.
- Try full-pay video poker. A 9/6 Jacks or Better machine returns about 99.54% with perfect strategy, far more than any slot area average.
- Be wary of airport slots. A Wizard of Odds survey ranked the Las Vegas airport last of 71 locations for slot payback. That survey is old (2001 to 2002), but the airport has a long reputation for tight machines.
- Join the players club. Cashback and free play don’t change the machine’s payback, but they give back some of what you play.
- Set a budget before you start. Even the loosest area still keeps more than 5% of every dollar played over time. Our gambling budget calculator helps you plan a trip.
Slot myths: are slots looser at night or at weekends?
No. Nevada’s rules don’t allow a game’s odds to be changed during a game, and payback changes have to go through formal processes rather than being switched on the fly for busy times. Our slot machine myths guide covers more of these.
Las Vegas slots vs online slots
Online slots usually publish their return to player (RTP), and most sit at roughly 94% to 96%. That’s higher than most of the Nevada area averages above, though RTP is a theoretical figure over millions of spins and NGCB win percentages are actual results, so they aren’t measured the same way. If you play online, check each game’s RTP in its info screen. Our highest RTP slots list and best payout casinos guide show where to start, and how to win at slots explains what really affects your results.
