21.com runs as a browser-based PWA — no .apk, no App Store app, just Add to Home Screen — fronting a casino and full sportsbook, and unlike many peers it shows a named operator and an Anjouan licence.
The essentials first. There is no Android .apk and no iOS App Store app — 21.com installs on both platforms the same way, as a home-screen web app.
Behind it sits a casino, a full sportsbook, and — for once in this space — a named operator and a licence number you can point to.

21.com runs as a browser-based PWA — no .apk, no App Store app, just Add to Home Screen — fronting a casino and full sportsbook, and unlike many peers it shows a named operator and an Anjouan licence.
The essentials first. There is no Android .apk and no iOS App Store app — 21.com installs on both platforms the same way, as a home-screen web app.
Behind it sits a casino, a full sportsbook, and — for once in this space — a named operator and a licence number you can point to.
Both platforms use the same Add to Home Screen route; nothing downloads, and it is free.
Your login settles across the browser and the shortcut, so there is no second sign-in.
Two products under one account. The casino runs slots, live-dealer tables, jackpots, crash games and a few exclusives like Gates of 21, from Pragmatic Play, Hacksaw Gaming, Nolimit City, Novomatic and Evolution; the sportsbook covers football, tennis, basketball, e-sports and motor racing with pre-match and in-play odds.
Game shows, Bonus Buy and Drops & Wins fill out the casino side, and the latest releases get their own row.
The cashier is broad and crypto-friendly. Cards run through Visa and Mastercard, with Apple Pay, Google Pay, Skrill, Neteller, MiFinity and Paysafecard as wallets, plus crypto — Bitcoin, Ethereum, Litecoin and USDT among them.
Deposits are instant, and it all runs from the same mobile cashier with no separate application to install.
Here 21.com stands out. It is operated by SkyHigh Innovations Ltd, a Belize-registered company, under Anjouan e-gaming licence ALSI-202511047-FI2 — a named operator and a licence number, backed by a GameCheck fair-play seal and audited RNG.
Anjouan is a lighter-touch regulator than Malta or the UK, so it is not top-tier, but this is a real, checkable licence rather than a blank. Read the terms and confirm your local rules before depositing.
The welcome side is a multi-deposit bonus with free spins, plus a first-week cashback and a small verify-and-connect bonus.
Loyalty runs through the 21 Elite Club, with cashback, tournaments and perks. The brand also sponsors MotoGP, which is unusual at this end of the market.
Support is 24/7 via live chat, with a Telegram channel and social links, plus FAQ, Bonus Rules and Responsible Gaming pages.
21.com is a cut above much of this space on the things that matter: a named operator, an Anjouan licence you can cite, a GameCheck seal, a big casino, a full sportsbook and crypto-friendly banking — all through a browser PWA with nothing to download.
The trade-offs are that the licence is Anjouan rather than a top-tier regulator, and the “app” is a home-screen shortcut, not a store download. For a licensed, no-install casino-and-sportsbook, it is a solid pick.
✅ Players who want a named operator and a checkable licence
✅ Fans of casino and sports betting under one account
✅ Crypto users — Bitcoin, Ethereum, Litecoin, USDT — and card players
✅ Players happy with a no-download, browser-based site
✗ Anyone who needs a Malta- or UK-tier regulator

Yes — it is operated by SkyHigh Innovations Ltd under an Anjouan e-gaming licence (ALSI-202511047-FI2), with a GameCheck fair-play seal. Anjouan is a lighter-touch regulator, so check the terms and your local rules.
No native app — both Android and iOS use Add to Home Screen to save the site as a free web app. There is no .apk or App Store version.
