How to play keno

1. Choose how many spots to play — usually 1 to 10.
2. Mark your numbers or use quick pick.
3. Set your stake and the number of draws.
4. 20 numbers are drawn from 1–80.
5. You're paid according to the game's paytable for your spots and matches.

Paytables differ between lottery keno and casino keno, and between games. Always check the paytable before you play.

Keno odds chart

Odds of hitting all your spots in a 20-from-80 draw:

This is pure math (hypergeometric probability) and is the same everywhere. It's why a 10-spot jackpot pays so much: you'd hit it about once in 8.9 million tickets.

Paytables and how to calculate a win

The paytable shows the multiplier for each number of matches. Example from casino keno (illustrative — every game has its own table):

Your win = stake × multiplier. A $2 bet on a 4-spot that hits 4 of 4 at ×50 pays $100. Games with many spots often pay for partial matches, and some pay for zero matches.

How many numbers should you pick?

• 1–3 spots — frequent, small wins;
• 4–6 spots — balance between frequency and size;
• 8–10 spots — rare, large wins; most tickets lose.

There is no "best" number of spots. What matters is the paytable and the game's RTP — compare them like you would compare slots.

Multipliers and bonus options

Many keno games offer a multiplier for an extra cost: a random multiplier (×2, ×3, ×5…) can boost your win. It raises the top prizes, but the extra stake is priced so the house edge stays.

Online keno and live keno

Online casino keno draws instantly via RNG and often has a free demo mode. Live keno shows a real or animated draw on a schedule. Lottery keno usually has a lower return than many casino games; casino keno RTP varies widely by game, so check the info screen.

Keno myths

Keno at Mostbet

Mostbet offers keno among its instant games, some with demo mode. New players can use the promo code NEW3000, but number games usually count little toward bonus wagering. As far as we know, Mostbet is not registered in Ontario — check the rules in your province first.

Keno vs. lottery vs. slots

Keno feels like a lottery but can be played at slot-like speed online. That combination makes it easy to play many tickets quickly, so the paytable and RTP matter even more.

Example: a 4-spot ticket over 100 draws

You play a 4-spot for $1 per draw, 100 draws. The chance of hitting 4 of 4 in 20-from-80 keno is about 1 in 326, so you'll most likely never hit the top prize in 100 draws. You'll hit 3 of 4 roughly once in every 23 draws and 2 of 4 about once in every 5 draws, depending on what the paytable pays for those. Over the session, the total you get back depends almost entirely on the paytable — two games with the same rules but different paytables can return very different amounts. This is why comparing paytables is the most useful keno "strategy".

Responsible keno play

Keno draws can run every few minutes in lottery venues and instantly online. Decide how many draws you'll play and your total budget before you start, avoid "auto-play until win" options, and remember that a near miss (3 of 4) is simply one of the expected outcomes, not a sign that a win is coming.
