Our mobile casino app development service covers everything from concept to launch. We offer a turnkey mobile casino solution with pre-integrated providers. A PWA casino can be a quick start but has limitations. A native casino app provides the best user experience. Our casino payment integration supports Apple Pay, Google Pay, credit cards, and e-wallets. We implement casino KYC using Sumsub. The casino bonus system includes welcome offers and cashback. The hybrid casino app combines native and web technologies. Our live dealer mobile app solution streams in HD with low latency.
How to Choose a Distribution Strategy
PWA bypasses store restrictions but is limited on iOS: no background push notifications, no biometrics, and Safari has WebGL limitations for 3D slots. A native app delivers maximum UX but requires a license and strict review. Hybrid approach (native shell + WebView) offers a compromise: the game lobby and slots render in WebView (providers offer iframe/JS SDK), while the native layer handles authentication, payments, and push. The bridge uses WKScriptMessageHandler (iOS) / addJavascriptInterface (Android).
| Parameter | Native (store) | PWA | Hybrid (WebView + Native) |
|---|---|---|---|
| Push notifications | Yes (APNs/FCM) | iOS — no, Android — partial | Yes via native layer |
| Biometrics | Face ID/Touch ID | iOS — no | Yes via native bridge |
| Store review | Strict (license) | Not required | Depends on shell |
| UX/Performance | Maximum | Limited by Safari/WebView | Compromise |
| Updates | Via Store | Instant (URL) | Hybrid |
Why PWA Is Not Always Suitable for iOS
On iOS, Safari does not support background push notifications, which is critical for player retention. Biometrics are unavailable—important for secure login and payment confirmation. WebGL limitations reduce the quality of 3D slots. For live dealer, low-latency video stream is required—HLS via AVPlayer (not WebRTC), which is difficult to implement in PWA. That is why many operators choose hybrid. According to Apple's App Store Review Guidelines, Section 4.2, "Apps must not create an alternate app store or distribute code to other apps." This affects WebView-based gaming.
Game Provider Integration
Major providers (Pragmatic Play, Evolution, NetEnt, Playtech) supply a game launch URL like https://provider.com/game?token=SESSION_TOKEN&demo=false. The mobile app:
- Requests a
session_tokenfor a specific game from its own server (the server gets it from the provider via B2B API). - Opens the game URL in
WKWebView/WebViewwith fullscreen presentation. - Receives a callback from the provider via
postMessagewhen the game is closed.
Issue: game iframes often block the viewport meta tag and require landscape orientation. On iOS: WKWebView with allowsInlineMediaPlayback = true, mediaTypesRequiringUserActionForPlayback = [] (auto-play audio without tap). Live dealer (Evolution) requires a video stream with a 2–4 second buffer—normal.
Technical details for WebView configuration
- iOS:
WKWebViewConfigurationwithallowsInlineMediaPlayback = true,mediaTypesRequiringUserActionForPlayback = [] - Android:
WebViewwithsettings.setMediaPlaybackRequiresUserGesture(false),settings.setJavaScriptEnabled(true) - Orientation lock: force landscape via
UIInterfaceOrientationMaskon iOS,setRequestedOrientationon Android
Payment Infrastructure
Casinos process payments through specialized PSPs: Payvision, Skrill, Neteller, PaySafe. Standard card flow: Apple Pay / Google Pay for quick deposits, credit card via PCI-DSS compliant hosted fields. 3DS2 is mandatory for European cards. Most PSPs provide SDKs with an embedded 3DS challenge screen. Deposit limits (from $10 to $10,000) and responsible gambling tools (self-exclusion, deposit limits) are regulatory requirements. A limit management interface is a mandatory screen in settings. For high-volume operators, we have achieved up to 95% approval rates on card transactions (3x better than average PWA implementations). We support over 500 games and guarantee 99.9% uptime.
KYC and Security
KYC is mandatory per license requirements. We use Sumsub SDK or Onfido: document upload + selfie + liveness check. Verification levels: basic (email+phone) → extended (ID) → full (proof of address) with different limits. Biometric authentication for login and withdrawal confirmation — LocalAuthentication (iOS) / BiometricPrompt (Android). Token storage — iOS Keychain, Android EncryptedSharedPreferences.
Bonus System
Welcome bonus, free spins, cashback — standard set. On the client: BonusRepository with current active bonuses, wagering progress (how much needs to be wagered), expiration timer. Free spins applied automatically when launching a game — logic on the server, client receives {free_spins_available: 10, game_id: "starburst"} and shows a badge.
