Keno vs bingo

Keno vs bingo: the short answer

Keno is a casino game. You choose some numbers from 1 to 80, the game draws 20, and the casino pays you from a fixed pay table depending on how many of your numbers match. Every win comes out of the house’s pocket, so the pay table is set to keep a share of all stakes. Online bingo is a shared game. Everyone buys tickets, numbers are called, and the first player to complete the required pattern takes the prize.

That makes them hard to compare on a single number. Keno has a house edge you can work out from the pay table, and on land it has been among the most expensive casino games: Wizard of Odds’ summary lists 25% to 29%. Bingo has no fixed edge. What you get back depends on the prizes on offer and how many tickets are bought, and the Gambling Commission’s own technical guidance accepts that the chance of winning at bingo can’t be stated in advance for that reason.

Online keno RTPs vary by game. If a keno game’s help screen shows its RTP, use that figure rather than any general range.

How each game works

Keno in brief

You mark between 1 and 10 numbers on a card of 80 (some games allow 15), choose a stake and start the draw. Twenty balls or numbers are drawn at random. Each of your numbers that appears is a “catch”, and the pay table tells you what each combination of picks and catches pays. Picking more numbers opens bigger top prizes but makes catching them all far less likely.

Bingo in brief

British bingo is usually 90-ball. Each ticket is a grid of three rows and nine columns holding 15 numbers and 12 blanks, and a strip of six tickets contains every number from 1 to 90 exactly once. Prizes come in stages: one line, two lines, then a full house. The North American 75-ball game uses a 5 × 5 card with a free centre and pays for patterns, and 80-ball bingo uses a 4 × 4 card of 16 numbers.

Keno vs bingo rules and formats side by side

The pay table point is the important one. In keno a pay table can be read and turned into a house edge. In bingo, the same ticket can be good or poor value depending on how full the room is. The specialty games hub covers both games and their relatives.

Who you play against: the house or the room

The Gambling Commission says bingo is the only form of gambling in the Gambling Act 2005 without a specific statutory definition. Its starting point is the 1978 Royal Commission’s description, “Bingo is a lottery played as a game”, and its guidance on how bingo is defined (opens in a new tab) sets out four features: players don’t stake against a bank, every ticket has the same chance of winning, players must take part to win, and each game has a defined end point.

Keno has none of those features. It is a banked game: you play against the operator, every player can win at once, and your chances don’t depend on anyone else. That is why keno sits alongside slots and roulette as a casino product, with a set return to player, while bingo is licensed as bingo. A business can hold remote casino and remote bingo permission on one combined Gambling Commission licence, which is why some UK sites offer both.

Keno odds: counting the draw

Keno odds come straight from counting. With one pick, 20 of the 80 numbers are drawn, so your chance is 20 ÷ 80 = 25%, or 1 in 4. For more picks, the chance of catching every one is the number of ways to choose your catches from the 20 drawn numbers, divided by the number of ways to choose your picks from all 80.

Two more useful figures: picking four numbers and catching exactly two happens about 21.3% of the time (1 in 4.7), and picking ten and catching none happens about 4.58% of the time, which is why some pay tables pay something for zero catches. The keno odds page has a fuller table.

Now see where the edge comes from. A pick-1 bet wins 1 time in 4, so a fair payout would be 3 to 1, returning your £1 plus £3. A game paying 2 to 1 instead would return £3 for every £4 staked on average: a 75% return and a 25% house edge. The draw itself is fair, as Wizard of Odds puts it; the edge lives in pay tables set below the true odds.

Bingo odds depend on the crowd

In bingo every ticket has the same chance, so your chance of winning a prize is simply your share of the tickets in play. Ignoring shared wins, if 300 tickets are in a game and you hold 6, you have 6 ÷ 300 = a 2% chance of taking the full house. In a quieter game of 60 tickets, the same 6 tickets give you 10%.

The chance is only half of the story. A busy game can have a bigger prize if the pot grows with ticket sales, and a quiet game with a fixed prize can be better value per ticket. That is why the Commission’s rules on displaying the likelihood of winning make an exception for bingo: the result depends on the eventual number of players. Before you buy, check the prize, the ticket price and, where shown, how many tickets are in play.

Keno vs bingo payouts and RTP

Keno is one of the few games with published returns from surveys of real pay tables. These figures are from US land-based venues, so they are context rather than a guide to any UK online game. The Wizard of Odds keno page (opens in a new tab) gives the detail.

Bingo has no equivalent table, because there is no single pay table. Prizes may be fixed, or may grow with the number of tickets sold, and each room or game shows its own terms. For comparison with other casino games, the house edge table lists the common figures, and keno sits near the bottom of it.

What an hour of keno could cost

Expected loss is stake × house edge, or stake × (100% − RTP). The table assumes 100 keno games at £1, an illustration only, at three different RTPs, so you can see how much the game’s setting matters. Read the actual RTP from the game’s help screen and use the house edge calculator for your own figures.

For bingo, cost is easiest to judge from the top down: decide what you are happy to spend on tickets for the session and treat it as the price of the evening. Keno results swing widely, especially with many picks, because most of the return comes from rare big catches. Bingo spend is predictable, because you know the ticket cost in advance, though prizes are not.

Speed, social play and how long a budget lasts

• Keno can be fast. An RNG game resolves a draw quickly, and UK rules require at least 5 seconds per game cycle for casino games other than slots.
• Bingo runs at the room’s pace. You buy tickets for a scheduled game, and the game lasts until its prizes are won.
• Bingo is social. Rooms often have chat and a shared atmosphere; keno is played alone.
• Keno puts you in control of risk. Fewer picks mean frequent small results; ten picks mean long gaps and rare big ones.
• Bingo spend is fixed up front. Once your tickets are bought, the game can’t cost more.

If you like a lottery-style draw with a live host, Evolution’s Mega Ball draws 20 of 51 balls on bingo-style cards and then adds a multiplier ball. It is a casino game, not bingo, so its prizes come from the house. Our online bingo vs Slingo comparison covers another bingo hybrid.

UK rules for keno and bingo

Running bingo for commercial gain in Great Britain needs a Gambling Commission operating licence, and the Commission warns that running any online bingo game without one, including over social media or video calls, breaks section 6 of the Gambling Act 2005 even for charity; see its page on running online bingo (opens in a new tab). Keno at an online casino falls under the casino rules: autoplay has been banned for all online casino games since 17 January 2025, non-slot casino games need at least 5 seconds per game cycle, and net spend and time played must be shown.

Since 19 January 2026, a promotion can’t mix gambling products, so an offer can’t combine casino play and bingo. Bonus wagering is capped at 10x the bonus. Age and identity must be verified before you deposit or play, and winnings aren’t taxed for UK players. The UK rules hub explains each rule, and the mixed-product ban page covers the offer change.

Which suits you: keno or bingo?

Keno suits players who enjoy picking numbers and want a quick solo draw, as long as they read the RTP first. Bingo suits players who want a social game with a fixed spend. For other head-to-head guides, see the comparisons hub.
