Keno is the lottery of the casino floor. You pick some numbers, the game draws 20 balls from 80, and you are paid on how many match. There is no skill to learn and no opponent to beat, and a round takes seconds. That simplicity is the appeal. It also hides the game’s one real trap: the same-looking keno game can pay back very different amounts depending on its paytable.
This page explains how online keno works, what your real odds are, and how to find a game worth playing.
Quick answer: Online keno draws 20 numbers from 80 and pays by how many of your picks match. The best online games return around the mid-90s, but others return far less, so the paytable and RTP matter more than the numbers you choose. Matching all 4 of 4 picks happens about 1 time in 326. Keno often counts 100% toward bonus wagering, which is rare for a non-slot game.

About this list. These are our general picks for players outside Ontario and Alberta, ranked by our overall review score. Keno is a side category at most casinos, and not all of these carry it, so search the lobby before you deposit. If you live in Ontario or Alberta, play at a provincially licensed site instead (see the section on provincial sites further down).
How Online Keno Works
- Choose your stake for the round.
- Pick your numbers from 1 to 80, usually between 1 and 10 of them, or let the quick pick choose.
- The game draws 20 numbers using a random number generator.
- You are paid by matches. The paytable shows what each combination of picks and hits pays.
Every number is equally likely on every draw. Hot and cold number displays show what has happened, not what will happen.
Keno Odds: What Your Picks Really Mean
These are exact odds for a standard game with 20 numbers drawn from 80:
| Numbers picked | Chance of matching all of them |
|---|---|
| 1 | 1 in 4 |
| 2 | 1 in 17 |
| 3 | 1 in 72 |
| 4 | 1 in 326 |
| 5 | 1 in 1,551 |
| 6 | 1 in 7,753 |
| 8 | 1 in 230,115 |
| 10 | 1 in 8.9 million |
Those long odds are why the top prizes look so large. A pick-10 ticket is a lottery ticket. A pick-4 ticket is closer to a normal casino bet. If you pick 4 numbers, here is what you should expect over many rounds:
| Matches out of 4 | How often |
|---|---|
| 0 | 30.8% |
| 1 | 43.3% |
| 2 | 21.3% |
| 3 | 4.3% |
| 4 | 0.3% |
Most rounds match one or none. That is normal, and it is why many keno sessions feel quiet between small wins.
Why the Paytable Matters More Than Your Numbers
The draw is fixed. The payout is not. Each game, and sometimes each number of picks within a game, has its own paytable, and that decides the return. Published figures vary enormously: the house edge in online keno runs from under 5% at the better games to well over 25% at the worst. Land-based keno is often worse still.
- Check the RTP in the info screen. Look for mid-90s or better. If no figure is shown, compare the paytable with another game.
- Compare the same picks across games. One game’s pick-4 can pay much more than another’s.
- Check whether RTP changes by picks. In some games it does.
At 95%, C$100 of bets costs about C$5 on average. At 75%, it costs C$25. Our explainer on return to player shows how that adds up over a session.
How Many Numbers Should You Pick?
There is no magic number. Picks change the shape of your results rather than guaranteeing a better deal:
| Picks | What it feels like | Suits |
|---|---|---|
| 1 to 3 | Frequent small results | Long, low-risk sessions |
| 4 to 6 | A mix of small wins and occasional larger ones | Most players |
| 8 to 10 | Long losing runs with a lottery-style top prize | Small stakes, for fun |
Choose the range that fits your budget, then find the game that pays best at that range.
Keno Variants
- Classic video keno. The standard 80-ball game with a paytable.
- Multiplier versions. Games such as Power Keno add multipliers on some draws, usually offset by lower base pays.
- Fast keno. Shorter rounds. The odds stay the same, but you bet more per hour.
- Live keno. Rarely offered, but some studios run ball-draw games with a host.
Keno and Casino Bonuses
This is keno’s quiet advantage. Most non-slot games count little or nothing toward wagering, but keno often counts in full. Our Casimba, BetPlays and Casilime reviews all found slots, scratch cards and keno counting 100%, and Dream Vegas allows only those games while a bonus is active.
That does not make keno a good way to clear a bonus unless the RTP is strong, because a weak paytable costs more than a good slot. Compare it with our list of low volatility slots and read our explainer on welcome bonus wagering before you decide.
Keno vs Other Casino Games
| Game | Typical return | Skill involved |
|---|---|---|
| Online keno, good paytable | Mid-90s | None |
| Online keno, poor paytable | Far lower | None |
| Online slots | 94% to 97% | None |
| European roulette | 97.30% | None |
| Baccarat, Banker bet | 98.94% | None |
If you like simple, no-decision games, online baccarat and European roulette usually cost less. Our ranking of the casino games with the best odds has the full picture.
Keno Myths
- “These numbers are hot.” Each draw is independent.
- “Consecutive numbers never come up.” Every combination is as likely as any other.
- “Quick picks do worse.” They have the same odds as numbers you chose.
- “Play the same numbers until they hit.” Past draws do not change future ones.
Keno at Ontario and Alberta Licensed Sites
Keno is a minor category at regulated casinos, so check the lobby. Our list of licensed Ontario online casinos covers that market, and our page on Alberta’s regulated casinos tracks the market that opened on July 13, 2026. Provincial lottery sites also run keno-style games, with their own paytables.
Is Online Keno Fair?
At a licensed casino, yes. The draw comes from a tested random number generator. What decides whether keno is good value is the paytable, not the fairness of the draw. Our explainer on whether online casinos are rigged covers testing, and our casino review methodology explains how we check games.
Treat It Like a Lottery
Keno rounds are quick, and the big prizes are very unlikely. Decide your budget before you start and stop when it is gone. Our page on responsible gambling in Canada lists support in every province.
