Betting Apps in Namibia: the JSB Betting App, Castle, Spin City and Supreme While the Board Licenses Bookmakers
Betting apps in Namibia arrive by two routes. Home-grown brands, JSB and Castlebet among them, post Android files on their own websites. Offshore sportsbooks such as 22Bet, Melbet and 1xBet publish store apps.

No Namibian bookmaker register existed yet in late 2026, because the Gambling Board was still assessing applications. Whatever licence an app prints is, for now, the only one it has.
Betting apps in Namibia built by offshore sportsbooks
Betting apps in Namibia from offshore operators come with Android and iPhone versions: 22Bet, Melbet and 1xBet each publish both. None of the three prints a fixed welcome offer for Namibian accounts, so the promotions tab inside the app is where terms appear.
A complaint about one of them starts with its support desk and ends with a foreign regulator. The Board's question-and-answer page treats unlicensed gambling as illegal, which is why its licensing round matters to every app user.
Local names and the offshore ranking are compared on the Namibia betting sites hub.

The JSB betting app, an Android file from JSB itself
The JSB betting app is an Android file hosted on JSB's own app page at jsbsports.bet. Before offering it, the page reads the phone's system type and switches to a second build for older handsets.
Inside, the menu runs from football and Aviator to casino, live tables, jackpots and horse racing. JSB also keeps shop counters around the country. The brand's Google listing mentions a deposit bonus of up to 325% with code JSB150, terms the promotion page spells out.
Installing needs one Android permission, which JSB's guide explains. Turning that permission off again afterwards keeps the phone as safe as it was before.
The Spin City betting app, linked in the site footer
The Spin City betting app hides in plain sight: its link sits at the foot of every page on spincity.co.na. The site leans towards slots, instant games and virtual sports, with sports betting alongside and a light category for slow connections.
The licence printed there, number 9547860, is Zimbabwean. Standing with the Namibian Board is the separate question to ask before a Namibian dollar goes in, since local licences were still pending through 2026. The Board's answer, not the footer, is what counts at home.
In Zimbabwe the same brand works mostly through a light mobile site, as the Zimbabwe betting apps page explains.
Castle betting app download and the safe install routine
A Castle betting app download begins at the Download App link in castlebet.com.na's footer. It installs outside the Play Store, like JSB's, so the same short routine applies to both.
- Try the Play Store first, and compare the developer name with the bookmaker's.
- With no store listing, go to the bookmaker's own website and use its app link.
- Approve the single install, sign in, and remove the permission again.
Copies forwarded in group chats are the danger, whatever the brand. A cloned betting app can read the login and card details typed into it, then empty both. Castlebet's own page is the only source worth trusting for its file.
The Supreme Betting app question, and the rules every app follows
Anyone looking for a Supreme Betting app in October 2026 found none to download on supreme-bet.com. The operator, registered as Supreme Electronic and Gaming CC, serves players through the mobile browser.
App or browser, the same law applies. The Gaming and Entertainment Control Act, 2018 sets the age at 18 and lets courts fine an operator N$20,000, or jail its people for up to two years, for taking a minor's bet.
The Board's consultation notices record a bookmaker workshop on 15 October 2026. South African apps, by contrast, already run under provincial licences, as the South African apps guide shows; the best betting sites list for Africa compares every market.
Android and iOS builds are both live, so the account follows the phone.
Balances run in coins, and payouts skip the bank.
Namibian betting apps, short answers
Where does the JSB app come from?
From JSB's own app page on jsbsports.bet. The page detects the phone's system type and offers a matching Android build, and the brand's guide explains the single permission the install needs.
How do I get the Spin City app in Namibia?
Through the link at the foot of every page on spincity.co.na. The site prints a Zimbabwean licence, so it is worth asking the Namibian Board about the brand's standing first.
Can I bet with Supreme Betting on a phone?
Yes, through the mobile browser. No app download was offered on supreme-bet.com in October 2026, and the operator trades as Supreme Electronic and Gaming CC. Pinning the site to the home screen makes it open like an app.
Do offshore betting apps hold a Namibian licence?
No. The Gambling Board was still assessing bookmaker applications in 2026, so 22Bet, Melbet and 1xBet rely on foreign licences, and a dispute ends with those regulators rather than with any authority in Windhoek.
What happens to an operator that lets a minor bet in Namibia?
Under the Gaming and Entertainment Control Act, 2018, it faces a fine of N$20,000 or up to two years in prison. The minimum age for players is 18, app or browser.
Which betting app downloads are safe in Namibia?
Those from the Play Store under the bookmaker's own developer name, or from the bookmaker's own website. Files forwarded in group chats can be clones that steal logins and card details.
