A full comparison of video keno machines and state lottery keno — house edge, draw speed, betting options, and which format gives players better value.
Keno comes in two primary formats available to US players: state lottery keno (sold at licensed retailers) and video keno machines (found at casinos, bars, and gaming venues). Both games use the same basic structure — pick numbers from 1–80, match drawn numbers, get paid — but they differ substantially on the factors that matter most to players.
| Factor | Video Keno (Casino) | Lottery Keno (State) |
|---|---|---|
| House Edge | 5%–15% (casino-set) | 25%–35% (state-set) |
| Draw Speed | Seconds per game | Every 3.5–5 minutes |
| Min Bet | $0.01–$0.25 | $1–$2 |
| Max Bet | $5–$25 per play | $20 (varies by state) |
| Spot Range | 1–20 spots | 1–12 spots (varies) |
| Bonus Features | Cleopatra, Caveman, Power, etc. | None (some states: multiplier add-on) |
| Location | Casinos, bars, gaming venues | Convenience stores, bars, retailers |
| Paytable Transparency | Varies — look for help screen | Published by state lottery |
| Multi-race / Multi-game | Available on most machines | Available (vary per state) |
| Jackpot Cap | Typically $100,000–$250,000 | Typically $100,000–$250,000 |
The single most important difference between video keno and lottery keno is the house edge — the percentage of each dollar wagered the game retains over time.
Video keno machines at tribal casinos are regulated by tribal gaming compacts, which typically require a minimum RTP (return to player) in the 85–95% range. This translates to a house edge of roughly 5%–15%. Individual machines vary — the paytable determines the exact figure, and casinos configure paytables within allowed ranges.
State lottery keno games are not subject to the same competitive pressures as casino games. Most state lottery keno games retain 25%–35% of each dollar wagered. Massachusetts Keno To Go, for example, has an RTP around 72% (28% house edge). Oregon Lottery Keno runs approximately 72–75% RTP.
In practical terms: for every $100 wagered over a session, a video keno player statistically loses $5–$15, while a lottery keno player statistically loses $25–$35. Over a long session at even modest bet sizes, this gap is significant.
Video keno draws complete in 3–5 seconds. A lottery keno draw runs every 3.5–5 minutes depending on the state. At first glance, faster seems better — more action, more excitement. But draw speed directly affects how quickly you can lose your budget.
A video keno player making one bet every 10 seconds plays 360 games per hour. A lottery keno player plays 12–17 games per hour. At $1 per game, the video keno player wagers $360/hour while the lottery player wagers ~$15/hour. Even with a lower house edge, the video keno player's total expected loss can be higher due to volume. Bet size management matters more in video keno than in lottery keno.
Video keno machines accept bets from $0.01 per credit on penny machines, making them accessible at very low stakes. A $1 bankroll can theoretically sustain many plays on a 1-cent machine picking a small number of spots. However, minimum-denomination play on most casino floor machines runs $0.25–$1 per play in practice.
Lottery keno games typically have a minimum bet of $1 per game, and most states set maximums at $10–$20 per game. The bet structure is simpler and more predictable.
Video keno machines offer game-specific bonuses that lottery keno cannot match. The Caveman Keno 8× multiplier, Cleopatra's final-ball double, and Power Keno's 4× boost all add small positive contributions to the base RTP. Some states offer a multiplier add-on (Ohio's Kicker, for example), but these are purchased separately and are equivalent to a separate side bet.
The mathematically correct answer is video keno — the lower house edge is meaningful over any significant volume of play. But "best value" isn't the only reason people play keno. Lottery keno's slower pace naturally limits exposure, and many players find the bar or lounge setting more enjoyable than a casino machine. Choose the format that fits both your math tolerance and your preferred experience.
Both formats involve a house edge. No bet size or spot selection changes the math. Set a firm session budget before you play — regardless of format. For problem gambling resources, call 1-800-522-4700 or visit our resources page.
