Reviewing Keno, 99.6% RTP.
Pick between 1 and 10 spots on an 80-number board, watch a draw of 20 numbers land, and get paid on however many of your picks hit. Keno keeps the format familiar to anyone who has played a lottery-style number game, but Galaxsys pushes the payout ceiling to 2000x on the highest pick sizes. Here is how the game works, where to play it, and what the numbers actually mean.

What is Keno?
Keno is an 80-ball number draw game from developer Galaxsys. Players choose between 1 and 10 spots from a board numbered 1 to 80, place a stake, then watch a draw of 20 numbers land. The payout depends on how many of the chosen spots match the draw and on how many spots were picked in the first place.
Larger pick sizes carry longer odds but a much higher ceiling. A small 1 or 2-spot pick lands more often for a modest multiplier, while the largest pick sizes chase the game's published 2000x maximum win when most or all chosen spots are hit.
At 99.6 percent, Keno carries one of the highest published RTP figures across the entire Galaxsys catalog, ahead of most of the developer's other number-draw and card titles.
In One Sentence
An 80-ball keno game where picking 1 to 10 spots and matching them against a 20-number draw can pay up to 2000x the stake.
How to Play Keno - Step by Step
The rules take a minute to learn. Pick numbers, set a stake, watch the draw.
Choose your pick size
Select between 1 and 10 spots from the 80-number board, either manually or with Quick Pick.
Set your stake
Adjust the bet amount using the plus buttons or a preset value before confirming.
Confirm the ticket
Lock in your selected spots and stake before the draw begins.
Watch the draw
20 numbers are drawn from the board of 80, one after another.
Check your matches
The payout table shows what each number of matched spots pays for your chosen pick size.
Manage your stake
Larger pick sizes chase the 2000x ceiling but land far less often. Set a session budget and stick to it.
Demo mode uses the same draw logic and the same 99.6 percent RTP. The only difference is virtual credits instead of real money.

Keno Demo - Try It for Free
Most casinos carrying Keno include a demo. Same 99.6 percent RTP, no registration, only virtual credits.
- Open the demo at SlotsGem, Mostbet or 22Bet, all three offer a free version.
- Start with a small 2 to 4-spot pick for your first 20 rounds.
- Wager $10 in virtual credits.
- Watch how often your spots get hit at that pick size.
- Try a larger pick size once you understand the payout table.
Skip the demo warm-up and it is easy to misjudge how rare a large pick-size hit really is.
Keno Strategy and Bankroll Management
There is no way to beat the built-in edge on a draw-based game. Three approaches can still change how a bankroll holds up.
Small Pick Sizes
Sticking to 2 or 3 spots lands more often for a modest payout, stretching a bankroll across far more rounds.
Mid-Size Picks
A 5 or 6-spot ticket balances a reasonable hit rate against a payout worth chasing.
Full 10-Spot Tickets
Chasing the 2000x ceiling on a full 10-spot pick loses far more sessions than it wins. Only play this with money you can afford to lose entirely.
The shared lesson: pick a stake size and a session length before the first ticket, and stick to both regardless of what the draw does.
Common Mistakes and How to Avoid Them
Patterns we noticed while reviewing player sessions at SlotsGem, Mostbet and 22Bet.
| Mistake | What Happens | Fix |
|---|---|---|
| Jumping straight to a 10-spot ticket | Bankroll drains fast chasing the 2000x ceiling that rarely lands | Start with 2 to 4 spots and increase the pick size gradually |
| Believing in "lucky" numbers | Repeating the same picks after a near miss | Each draw is independent of the last, past results do not predict the next |
| Chasing losses | Doubling the stake after two losing tickets in a row | Set a daily deposit limit, take a break after a losing session |
| Skipping the demo | Misjudging how rare a large pick-size hit really is | Play at least 20 demo rounds before switching to real money |
| Unprepared bankroll | Playing with money set aside for bills | Only play with disposable income |
Keno App - iOS, Android, and APK
Galaxsys does not officially publish a standalone Keno app. Anything with that name in an app store is unrelated to the developer.
Safe
- Mobile websites at SlotsGem, Mostbet, 22Bet and Wazamba, all in-browser.
- Official casino apps from Google Play or an APK hosted on the operator's own domain.
- iPhone via Safari or the casino's own iOS app.
Avoid
- "Keno predictor" apps from unknown sites.
- Social media ads promising guaranteed 10-spot hits.
- Apps that claim to run the draw offline.
Mobile vs desktop: same board, same draw logic, same 99.6 percent RTP.
Payouts, KYC, and Payment Methods
The game runs in-browser with no installation, so problems tend to sit around it: deposits, verification, or a slow mobile connection.
Payout Is Delayed
Offshore casinos require KYC after a first win. SlotsGem and Mostbet usually clear it in 2 to 5 hours, 22Bet and Wazamba in 24 to 48 hours. Upload an ID, a selfie, and a proof of address right after registering to avoid delays.
Payment Methods
Reliable options across the four casinos include Visa, Mastercard, Skrill, Neteller and cryptocurrencies such as BTC, ETH and USDT. Availability of any specific method still depends on your country.
Game Lags on Mobile
Keno is technically light and runs fine on 4G. Switch off any VPN and clear the browser cache if the board stutters. If the demo lags too, the issue sits with the casino, not the game.
Keno vs Keno Express and Lotto Boom
Keno Express and Lotto Boom are the closest Galaxsys number-draw titles in the same catalog. The differences matter for anyone choosing between them.
| Parameter | Keno | Keno Express | Lotto Boom |
|---|---|---|---|
| Developer | Galaxsys | Galaxsys | Galaxsys |
| RTP | 99.6% | 97% | 98% |
| Max Payout | x2000 | 97x bet | 1000x |
| Format | 80-Ball, Pick 1-10 | Fast Single/Range Draw | Lottery-Style |
| Round Speed | Standard | Faster | Standard |
Bottom line: Keno carries the highest published RTP and the biggest ceiling of the three, Keno Express suits players who want faster rounds, and Lotto Boom leans closer to a traditional lottery format.
Security, Pros and Cons
Keno runs on RNG-driven draw logic hosted by the casino operator rather than the player's device, so the drawn numbers cannot be predicted or manipulated from the browser.
Pros
- 99.6 percent RTP, among the highest in the Galaxsys catalog.
- Flexible pick sizes let players choose their own risk level.
- Free demo available at every tested casino, no registration needed.
Cons
- No standalone volatility rating published by Galaxsys.
- Large pick sizes carry very long odds despite the high headline RTP.
Keno Reviews - Players Share Their Results
Feedback gathered from player forums and our own review of sessions at SlotsGem, Mostbet and 22Bet.
"Picked 8 spots for a few weeks straight at Mostbet, hit 6 of them once and the multiplier made the whole month worth it."
"The 99.6 percent RTP is one of the highest I have actually seen on a Galaxsys title, but hitting a full 10-spot ticket is still rare."
"Quick Pick is handy when I do not want to think about numbers. Withdrawal from 22Bet arrived within a day through Skrill."
"Went straight for a 10-spot ticket hoping for the 2000x ceiling and burned through my session budget in twenty minutes. Should have started smaller."
"Slower and calmer than crash games, which is exactly what I wanted after a stressful week. A 4-spot pick keeps hits coming often enough to stay interested."

Which payment methods work?
Keno stands out in the Galaxsys catalog on RTP alone, and the flexible pick sizes let cautious and aggressive players share the same table without either feeling out of place. The 2000x ceiling is real but rare, and treating a large pick size as a lottery ticket rather than a reliable strategy keeps expectations honest. Start small, learn the payout table, then scale the pick size up gradually.
