How does online keno work and how are the numbers drawn?

If you're wondering whether the numbers in online keno are genuinely random — or whether the house has some unseen hand in the outcome — that's the right question to ask before you play. The short answer is: the draw mechanism is independently certified, and every number has an equal shot. Here's exactly how it works.

The Basic Structure

Keno is a pick-and-match game built around a large number pool. Twenty numbers from 1 through 70 are drawn each round, and players decide how many of those numbers they want to match. You can choose anywhere from two numbers (a 2 PICK) up to ten numbers (a 10 PICK). Once you've locked in your selection, the draw happens and you're paid based on how many of your picks appear in the winning set — the more you match, the higher the prize tier.

The flexibility is a big part of the game's appeal. Playing fewer numbers means smaller prizes but better odds of hitting something; playing more numbers opens up larger payouts but makes a full match considerably harder. Generally, the odds of winning a draw-based lottery depend on two things: how many numbers must be matched, and the size of the number pool.

How the Numbers Are Actually Drawn

Online keno doesn't use physical balls. The Daily KENO numbers are drawn by a random number generator (RNG). This is the same core technology that powers online slots and other digital games — a continuously running algorithm that produces statistically unpredictable outputs.

The credibility of that process rests on third-party oversight. Daily Lottery numbers are drawn using a certified random number generator. The random number generator is certified for randomness by an independent third party — this ensures that every number has an equal chance of being drawn with every draw. That certification matters: it means the RNG has been tested against recognized statistical standards, not just declared random by the operator.

A direct consequence of this: there is no way to tell which numbers will be drawn at any given time. Past results carry zero predictive weight. Each draw is entirely independent of the one before it.

Draw Frequency and Playing Online in Ontario

In Ontario, OLG's Daily KENO runs on a fixed schedule. There are two draws per day — a MIDDAY draw at 2 p.m. Eastern Time and an EVENING draw at 10:30 p.m. Eastern Time. If you buy your ticket before 2 p.m., it's valid for the midday draw; after 2 p.m., it's valid for the evening draw; a ticket bought after 10:30 p.m. is valid for the next day's midday draw.

For players on registered Ontario online casino platforms (as opposed to OLG.ca's lottery-style keno), the keno titles available in the casino game library use the same RNG principle but operate on much faster cycles — sometimes a new draw every few minutes. The RNG certification requirement applies across the regulated market, so the integrity mechanism is consistent regardless of which licensed platform you're on.

The Odds Reality

Keno carries a meaningful house edge, and it's worth being clear-eyed about that. The prize structure is set so that the payouts across all possible outcomes are less than the total amount wagered — that gap is the house's margin. House edge and RTP are averaged across all players and don't determine a single player's likelihood of winning for a specific bet or session. No pattern of picks, no "hot" numbers, and no betting sequence changes the underlying math. There's no secret to selecting winning numbers — whether you select your own or ask for a Quick Pick, your odds of winning remain the same.

Keno is best approached as entertainment with a known cost, not as a way to generate income. If you ever feel your play is getting out of hand, ConnexOntario's problem gambling helpline is available 24/7 at 1-866-531-2600. Ontario's regulated online gambling sites also display the iGaming Ontario and BetGuard logos — those are your signal that the platform operates under AGCO oversight, and BetGuard (betguard.ca) gives you a single point of contact to self-exclude from all licensed Ontario operators at once if you need it.
