The Best Online Keno Casinos UK 2023

Looking to take a chance on your lucky numbers? Online keno is the game for you! It works a bit like a lottery — but you won’t have to wait for the weekly draw to come around! 

As keno has somewhat of a lower profile than other casino staples like roulette or slots, it can be hard to find a site with a good range of online keno games. But here at, our experts have selected the best keno casino sites to make your search easy. Keep scrolling and we’ll explain everything you need to know about online keno — or skip straight to our comparison table of the best online keno sites around!

Online Keno Casinos

The game of keno has existed for centuries. In fact, popular legend has it that an early incarnation was used to raise funds to build the Great Wall of China, thanks to the widespread enjoyment of the game among the population. Fast forward to today and you can play keno online from the comfort of your own home — we’re not sure they saw that one coming when they were laying the Great Wall’s bricks!

So, how does keno actually work? You can almost think of it as a combination of bingo and lottery gameplay. Most keno is played with the numbers 1–80. Participants pick a selection of numbers or ‘spots’ on the keno board — at least one and no more than 10, 15, or 20, depending on the game. Firefly Keno by 1X2gaming, for example, is a 15-spot keno game, although we’ve only picked eight numbers in the round pictured below. 

The payout depends on both how many spots you select, and how many of these numbers are drawn or ‘hit’. The more spots you pick, the higher the potential payout. At the same time, the chance of hitting all your spots fluctuates depending on how many you pick — so an eye for the odds is important if you want to get the best value! 

When deciding your keno strategy, take a look at the paytable and think about what you’d prefer: a slim chance at the jackpot with maximum spots, or better odds of winning a smaller amount with fewer spots?

Keno RTP

If you want to know the optimal number of spots to bet on, it’s worth checking the help section for the RTP or house edge. RTP stands for return to player and is an estimate of how much a casino game is expected to pay out in comparison to how much is paid in. In Firefly Keno, the RTP for one spot is 87.5%, but the maximum RTP is 95.81% when you pick just three spots. The average RTP for this online keno game sits at 92.82%.

How We Review Online Keno Casinos

Before we recommend any online casino, it’s put through its paces by our expert reviewers. We look at a myriad of factors, from the nuts and bolts of the keno casino all the way to the finishing flourishes. Below are the areas we look at in detail.

  • Licensing – The first port of call is a licence from the UK Gambling Commission. This is essential. Not only is it a legal requirement for sites that offer online gambling in the United Kingdom, but it provides a degree of safety to players. We only recommend licensed and regulated keno casinos at
  • Bonuses and Promotions – As a new player, you’ll usually receive a welcome bonus when you sign up. But how does the offer stack up against the competition? Are the terms and conditions reasonable? And can you use your bonus for online keno? We also look at ongoing promotions like cashback or reloads for existing players.
  • Games Selection – Online keno games may not have the diversity of slots, or even roulette and blackjack, but that’s no reason for a casino to slack. We like to see plenty of variants in all categories: keno, table games, slots, and live casino games from the biggest and best software providers. 
  • Fast Withdrawals – Once you request a payout, how long does it take to receive your money? For many online keno players, fast withdrawals are a top priority. We love sites that keep internal processing times down while offering the quickest payment methods such as e-wallets or Visa Fast Funds. 
  • Site Design – When it’s done well, site design isn’t always something you notice. Done badly, however, and you’ll be met with frustration at every turn. We look for keno casinos that are laid out logically and free from technical hitches. Appearance also plays an important role in the overall casino experience.
  • Mobile – A game of keno is quick to pick up and play, so it’s well suited for mobile devices. Many of our readers play exclusively via their phones, so strong mobile compatibility is a must. Our recommended keno casinos are optimised for mobile browsers, but some of the best sites offer a native app you can download for Android and iOS handsets.
  • Customer Support – The best online casinos make it easy to get in touch should you run into any problems. Live chat, email, and phone — the more boxes ticked, the better. To score full marks here, support should be available around the clock so you’re covered no matter what time you play.

Keno Online Bonus Types

An online casino bonus is a fantastic way to kick off your time at one of our top keno sites. Essentially, a bonus gives you a chance to win some money without putting your own cash on the line. These promotions come in a number of different formats — we’ve explained the most common ones below. 

Matched Deposits

Likely your best bonus option for playing online keno, a matched deposit is the most flexible. How does it work? When you make your first deposit at the casino, you’ll receive extra bonus credit which can be used to place bets. How much you get depends on the size of the offer. 

In the case of a 100% match up to £50, a £50 deposit would net you the same amount in bonus credit, giving you a total of £100 to play with. If you want to play online keno with your matched deposit bonus, be sure to check it’s eligible in the T&Cs as there may be some restrictions. Live dealer games are often excluded from matched deposit offers as well.


Available to new and existing players alike, cashback is a valuable offer that will see you get more out of your budget. This promotion sees players receive a portion of their net deposits, bets, or losses back as bonus credit or withdrawable cash. It’s either calculated daily, weekly or monthly, and percentages run from around 1% to 10%. Once you’ve signed up at a keno casino that offers cashback, check if you need to opt in or are automatically enrolled in the bonus.

Free Spins

Fancy a go on the slots without laying down your own money? Free spins give you the chance to do so, along with the possibility of winning some cash at the same time. While many online keno casinos feature huge libraries of slot games, a free spins offer is generally only valid for one or two chosen titles — Book of Dead and Starburst are a couple of popular choices. How many spins you get varies, with most bonuses sitting somewhere between 10 and 100 free spins. They’re usually valued at the minimum stake, with any winnings subject to wagering requirements before they can be withdrawn. 

No Wagering Bonus

Wagering requirements are a bit of a nuisance when it comes to casino bonus offers. After all, you won’t be able to withdraw any resulting winnings until they’re met. There is an alternative, however — a no wagering bonus does away with this requirement, allowing you to withdraw resulting winnings straight away. 

Whether from free spins or matched deposit, any profit is yours to keep. These player-friendly bonuses are usually smaller in size and may come with other restrictive terms like low win limits, but they’re still a great choice if you want the best chance of taking home some extra cash.

Keno Casino Payments

Before you can play keno online with real money, you’ll need to make a deposit. Our recommended casinos have plenty of options for managing your bankroll, each with different benefits and drawbacks. And once it’s time to withdraw, which option is best? Keep reading to find out.


The largest payments network in the world, Visa issues debit cards for many bank brands and is almost universally supported at online keno casinos. Visa debit payments are familiar to most online gamblers — just tap in the card info and confirm the transaction. You’ll be eligible to claim a bonus when you deposit with Visa, and the money will land in your casino wallet instantly. Withdrawals can be slower, taking 3–5 days unless the site supports Fast Funds — in which case they can arrive within an hour. 


Payments intermediary Trustly uses Open Banking to transfer funds directly between your bank account and the keno casino. Once you log into the secure Trustly portal with your online banking credentials, you can make deposits and withdrawals with just a few clicks. Deposits are instant, and payouts usually arrive within a day or two. Bonus eligibility is good with Trustly as well.


A prepaid card such as Paysafecard is a great option if you’re hesitant to share bank details online. Simply buy the vouchers at a participating retailer and transfer the value to your casino account using the printed code. As you’re limited to the value of the voucher, Paysafecard can help you manage your gambling spend too. Unfortunately, withdrawals via this payment method aren’t supported.


Leading e-wallet PayPal is available at many online keno casinos, and touts a range of benefits and features for managing your money. PayPal transactions can be completed with just your registered email and password for quick and simple deposits and withdrawals. Cashing out to PayPal is one of the quickest options, with keno payouts usually arriving on the same day they’re requested. The biggest drawback? e-Wallets are frequently excluded from claiming a welcome bonus.

  • What is keno?

    Keno is a lottery game where players win based on numbers that are drawn at random. Most keno games are played with up to 20 numbers or ‘spots’. Players choose how many and which spots to play on their keno ticket, and how much they want to bet. A random number generator (RNG) then decides the winning numbers in the keno draw. The potential payout is based on how many spots you choose and how many of them hit.
