How to Play Keno

How Keno Works

The basics:
1. A keno card shows numbers 1–80
2. You choose ('spot') 1–20 numbers (depends on casino; most allow 1–10)
3. The casino draws 20 numbers randomly from 1–80
4. Winnings are based on how many of your picks ('catches') match the drawn numbers

Payout is determined by a pay table that varies by how many numbers you picked (your 'spot count') and how many matched.

Keno Pay Table Example

Example pay table for 'Pick 5' (choosing 5 numbers from 80):

| Catches | Payout |
|---------|--------|
| 5 of 5 | 450:1 |
| 4 of 5 | 15:1 |
| 3 of 5 | 2:1 |
| 2 of 5 | 1:2 (you keep stake) |
| 0–1 of 5 | Loss |

Pay tables vary significantly between casinos and keno variants. Always check the specific table before playing — the house edge varies from 20–35% depending on the operator.

Keno Odds and House Edge

Keno has one of the highest house edges of any casino game — typically 20–35%. This is significantly higher than:
- Blackjack with basic strategy: 0.5%
- Baccarat (banker bet): 1.06%
- European Roulette: 2.7%
- Slot machines: 3–12%

The probability of matching all 5 numbers in a Pick-5 game is approximately 1 in 1,551. The payoff of 450:1 represents strong house edge relative to the true odds.

Keno is best understood as an entertainment product similar to a lottery — played for fun with small bets, not as a value game.

Online Keno vs Live Keno

Online keno: RNG (Random Number Generator) based — draws are instantaneous. Can play dozens of rounds per minute. The fast pace amplifies the house edge's impact — higher hourly expected loss despite smaller per-bet edge versus time.

Live keno: Physical ball draws shown via video stream or in-person at land casinos. Slower pace — one draw every 3–5 minutes. Lower hourly expected loss due to pace despite same per-bet edge.

For casual play, live keno at a land casino or slow-pace online keno is preferable to rapid-fire online RNG keno for bankroll longevity.

Is There Any Strategy in Keno?

No — number selection has zero effect on outcomes. Each draw is independent. 'Hot numbers' (frequently drawn) and 'cold numbers' (rarely drawn) are gamblers' fallacy — every number has the same 25% chance of appearing in any given draw (20 out of 80 numbers).

The only meaningful strategy decisions in keno are:
1. Which pay table to use — compare payout structures across casinos
2. How many spots to pick — more spots generally increase volatility (bigger max wins, more losing combinations)
3. Bet size — smaller bets extend session length against a high house edge
