Quick answer: Keno has the worst house edge of anything on a casino floor — commonly 20% to 30%, against roughly 1% for baccarat and 0.5% for blackjack. Every peso you put through a keno ticket costs you twenty to thirty times what the same peso costs at a blackjack table. The jackpot is what sells it; the maths is not close.
How Keno Works
Eighty numbers exist. Twenty are drawn. You pick somewhere between one and ten numbers — a “spot” ticket — and are paid according to how many of your picks appear among the twenty drawn.
That is the whole game. There are no decisions after you commit, no strategy that alters the draw, and no skill component whatsoever. It is a lottery running every few minutes.
The House Edge, In Context
| Game | Typical house edge | Cost per ₱10,000 wagered |
|---|---|---|
| Blackjack (basic strategy) | 0.5% | ₱50 |
| Baccarat (banker) | 1.06% | ₱106 |
| Craps (pass line) | 1.41% | ₱141 |
| Roulette (single zero) | 2.70% | ₱270 |
| Slots | 4% – 6% | ₱400 – ₱600 |
| Keno | 20% – 30% | ₱2,000 – ₱3,000 |
Read the right-hand column rather than the percentage. Ten thousand pesos cycled through blackjack has an expected cost of about fifty pesos. The same money through keno expects to lose two to three thousand. Nothing else on the floor is in that range — not the worst slot, not the worst proposition bet in craps.
Why the Jackpot Never Compensates
The appeal is the top prize on a 10-spot ticket, which can pay thousands to one. The problem is what has to happen to collect it.
Hitting all ten numbers on a 10-spot ticket is roughly a 1 in 8.9 million event. A payout of a few thousand to one against odds of nearly nine million to one is not a jackpot in any meaningful sense — it is a rounding error dressed up as one. The prize is large enough to imagine and small enough, relative to its true odds, that it contributes almost nothing to the game’s return.
This is the same structural point we make about progressive jackpots: a headline figure and a realistic expectation are different quantities, and the gap between them is where the operator’s margin lives.
The Only Thing That Changes Your Return
You cannot improve keno with strategy, because there are no decisions. Number selection is irrelevant — every combination has identical probability, and picking birthdays, “hot” numbers or a symmetrical pattern on the card changes nothing at all.
One lever exists: the pay table. Keno pay tables vary enormously between operators, and the difference between a generous one and a poor one can be ten percentage points of return on otherwise identical games. If you are going to play, compare the pay tables and pick the best one. That is the entire available skill.
Online keno is generally better than the lounge or lottery-style versions, sometimes landing nearer 5–10% — still poor, but a different category of poor. Check the published return before you play rather than assuming.
Frequently Asked Questions
Are some keno numbers luckier than others?
No. Each draw is independent and every number is equally likely. “Hot” and “cold” number displays are a record of the past with no bearing on the next draw — they exist because they encourage play, not because they inform it.
How many spots should I pick?
It barely matters for your expected loss, which is set by the pay table rather than the number of spots. Fewer spots means smaller, more frequent wins; more spots means rarer, larger ones. The average outcome is roughly the same and roughly bad either way.
Is online keno better than casino keno?
Usually, yes. Online versions often run a materially better return than the traditional lounge or lottery format. It is still one of the weakest games available, so “better” here means less bad rather than good.
Can any system beat keno?
No. Progressive staking, number patterns and chasing systems all leave the house edge exactly where it was — they only change how quickly you reach your limit. The same logic applies here as in our breakdown of roulette betting systems.
Why does anyone play it, then?
Because it is slow, cheap per ticket, requires no knowledge, and sells a large number. Played as an occasional lottery ticket at small stakes that is a defensible use of entertainment money. Played at volume it is the most expensive way to gamble in the building.
Final Thoughts
We try to be even-handed about most games, because most have a defensible case at the right stakes. Keno is the exception where the numbers do not permit one. At a 20–30% edge you are paying an enormous premium for a jackpot whose odds are close to nine million to one.
If you enjoy it, treat it as a lottery ticket: small, occasional, and budgeted as entertainment rather than as a bet with any prospect of return. If you want the same amusement at a fraction of the cost, almost anything else on the floor qualifies — our comparison of table games against slots sets out the realistic alternatives.
