The one rule that matters
Every slot keeps a percentage of everything bet on it — the house take. Your expected cost is always take × total dollars you spin through, and no machine is ever "due": every spin is independent. So the whole game is picking the machine with the smallest take, at the biggest denomination you can afford. Denomination is destiny: the same casino keeps roughly 3–5% on a $5 machine and 10–12% on a penny machine. Stick with one good machine — hopping changes nothing about your odds, it just drifts you toward higher-take machines.
🏆 Top 10 machines — Atlantic City (best first)
| # | Machine | Play it at | House take | |
|---|---|---|---|---|
| 1 |  | Pinball Double Gold | $5 · High Limit | ~3–4% |
| 2 |  | Double Top Dollar | $5 · High Limit | ~3–5% |
| 3 | Double Diamond (classic 3-reel) | $5 · High Limit | ~4–6% | |
| 4 | Pinball Double Gold | $1 | ~5–6% | |
| 5 | Double Top Dollar | $1 | ~5–7% | |
| 6 | Wheel of Fortune (3-reel) | $1–$5 | ~5–8% | |
| 7 |  | Dragon Link “Happy & Prosperous” (fat Buddha) | $1 | ~7–9% |
| 8 | Lightning Link | $1 | ~7–10% | |
| 9 | Buffalo Gold | penny–$1 | ~9–11% | |
| 10 | Dragon Link / 88 Fortunes | penny | ~10–12% |
Per-machine figures are the typical configured ranges for each game/denomination class — casinos don't publish per-machine settings. The casino-wide figures below are the official ones.
📍 House take by casino — Atlantic City
Official overall slot hold for every Atlantic City property — the average across all that casino's machines. Source: NJ Division of Gaming Enforcement, Monthly Gross Revenue Reports, September 2026.
| Casino | Slot hold | Expected ROI |
|---|---|---|
| Harrah's | 8.9% | −8.9% |
| Borgata | 9.4% | −9.4% |
| Ocean | 9.4% | −9.4% |
| Resorts | 9.7% | −9.7% |
| Golden Nugget | 9.8% | −9.8% |
| Hard Rock | 9.9% | −9.9% |
| Bally's | 10.0% | −10.0% |
| Caesars | 10.0% | −10.0% |
| Tropicana | 10.1% | −10.1% |
Citywide average ≈ 9.6% (Sept 2026: $177.9M kept on $1.856B wagered). The spread between the "tightest" and "loosest" casino in town is only 1.2 points — the machine and denomination you choose matter far more than which casino you walk into.
🏆 Top machines — Las Vegas (best first)
| # | Machine | Play it at | House take |
|---|---|---|---|
| 1 | Pinball Double Gold | $5 · High Limit (locals casinos have the most) | ~3–4% |
| 2 | Double Top Dollar | $5 · High Limit | ~3–5% |
| 3 | Double Diamond (classic 3-reel) | $5 · High Limit | ~4–6% |
| 4 | Pinball / Double Top Dollar | $1 | ~5–7% |
| 5 | Wheel of Fortune (3-reel) | $1–$5 | ~5–8% |
| 6 | Dragon Link “Happy & Prosperous” (fat Buddha) | $1 | ~7–9% |
| 7 | Lightning Link / Buffalo Gold | penny–$1 | ~8–11% |
| 8 | Dragon Link / 88 Fortunes | penny | ~10–12% |
Where in Vegas: the locals casinos (South Point, Red Rock, Green Valley Ranch, the Stations and Boyd properties) are famously looser than the Strip — same machines, set to keep less. Downtown (Fremont Street) generally beats the Strip too. On the Strip itself, play the High Limit classics and skip the penny banks near the walkways.
Per-machine figures above are typical configured ranges. Nevada publishes slot hold by area and denomination, not by casino — the official area figures are below.

| Area | Slot hold | Expected ROI |
|---|---|---|
| Clark County (all) | 7.12% | −7.1% |
| Las Vegas Strip | 7.22% | −7.2% |
| Downtown Las Vegas | 7.56% | −7.6% |
Strip hold by denomination (August 2026):
| Denomination | Slot hold |
|---|---|
| $25 | 5.94% |
| $1 | 6.90% |
| Multi-denomination (most of the floor) | 7.08% |
| 5¢ | 7.35% |
| $5 | 7.46% |
| 1¢ | 9.72% |
| 25¢ | 11.20% |
Single-month denomination figures are noisy in thin categories (the 25¢ number comes from only 634 Strip machines). The stable 12-month pattern statewide: pennies ≈8.9% > multi-denomination ≈7.0% > $1 ≈6.3% > $5 ≈4.4%. Bigger denominations cost less — same rule as Atlantic City.
🏆 Top machines — Florida (best first)
| # | Machine | Play it at | House take |
|---|---|---|---|
| 1 | Pinball Double Gold | $5 · High Limit (Hard Rock Tampa / Hollywood) | ~3–4% |
| 2 | Double Top Dollar | $5 · High Limit | ~3–5% |
| 3 | Double Diamond (classic 3-reel) | $1–$5 | ~4–7% |
| 4 | Wheel of Fortune (3-reel) | $1–$5 | ~5–8% |
| 5 | Dragon Link “Happy & Prosperous” (fat Buddha) | $1 | ~7–9% |
| 6 | Lightning Link / Buffalo Gold | penny–$1 | ~8–11% |
| 7 | Dragon Link / 88 Fortunes | penny | ~10–12% |
Florida specifics: the big floors are the Seminole Hard Rocks (Tampa and Hollywood) — tribal casinos, which do not publish their slot hold (their gaming compact only sets an 85% minimum average payout floor, not a disclosed figure), so the ranges above are the typical settings for each class. The state-licensed racinos do report — and they run looser than Atlantic City: 6.53% statewide hold in August 2026. Same rule as everywhere: $5 classics in High Limit are the cheapest seats in the state.

| Casino | Slot hold | Expected ROI |
|---|---|---|
| Magic City Casino (Miami) | 5.75% | −5.8% |
| Casino at Dania Beach | 5.89% | −5.9% |
| Big Easy Casino (Hallandale Beach) | 5.98% | −6.0% |
| Casino Miami | 6.11% | −6.1% |
| Gulfstream Park (Hallandale Beach) | 6.32% | −6.3% |
| Calder Casino (Miami Gardens) | 6.97% | −7.0% |
| Hialeah Park Casino | 7.18% | −7.2% |
| Harrah's Pompano Beach | 7.99% | −8.0% |
Statewide racino average: 6.53% hold (93.47% paid back), August 2026. The Seminole tribal casinos (Hard Rock Tampa, Hard Rock Hollywood, Coconut Creek) publish no hold figures at all — anyone quoting you a specific Seminole hold % is guessing.
