Pragmatic Play mobile slots are the bridge case for KAYU’s mobile registry: the asset bundles are heavy enough that an APK install saves meaningful Filipino mobile data, but the PWA install path is clean enough that most mobile players will not feel the friction. Sugar Rush mobile and Sweet Bonanza mobile are the two Pragmatic Play titles KAYU benches most often, and they show different APK-vs-browser ergonomics. This page documents the mobile data per spin, the session-length retention numbers, the install paths, and the decision framework for picking APK or browser for each title.
Pragmatic Play mobile bench — head-to-head
| Metric | Sugar Rush mobile | Sweet Bonanza mobile |
|---|---|---|
| Asset bundle (APK) | 22 MB | 28 MB |
| First-load PWA payload | 4.8 MB | 5.6 MB |
| KB per spin (APK) | 52 KB | 64 KB |
| KB per spin (browser) | 61 KB | 78 KB |
| APK retention (avg session) | 38 minutes | 41 minutes |
| Browser retention (avg session) | 33 minutes | 36 minutes |
| APK retention advantage | +15% | +14% |
| Observed RTP (APK bench) | 96.52% / 11,844 spins | 96.48% / 8,920 spins |
Filipino mobile session length — the retention KPI
Mobile session length is KAYU’s primary Pragmatic Play retention KPI because the thermal envelope on Filipino mid-range phones is the dominant session-length limiter. APK sessions average longer than browser sessions on both titles for two reasons:
- No browser-shell overhead. Chrome Android renders the WebView on top of the slot canvas; the APK skips that layer and frees ~10–15% sustained CPU.
- Local asset caching. APK install ships the entire art bundle locally; browser mode re-fetches sprites on first paint each session even with the service worker active.

PWA as the middle path
PWA install is the middle ground — cleaner than browser-only because the icon lives on the home screen and the service worker caches assets between sessions, but lighter than full APK because there is no Android package to side-load. Sugar Rush PWA holds 96.52% observed RTP across our 11,844-spin bench (see the Sugar Rush PWA RTP bench) and the 5-second install path is documented in the Chrome Android PWA install walkthrough. iPhone players running iOS Safari follow the iOS Safari PWA install walkthrough — iOS gets PWA only because the App Store does not allow casino apps in the Philippines.
APK vs browser decision matrix — which to install
| Player profile | Recommended install | Why |
|---|---|---|
| Daily session 30+ min, Android, mid-range phone | APK | Retention lift + thermal headroom + local caching |
| Daily session 10–30 min, Android, flagship phone | PWA | Throttle is not the limiter; PWA matches APK in feel |
| Casual weekly session, Android | Browser | No install friction; data cost negligible at weekly cadence |
| iPhone, any session | PWA (Safari only) | App Store does not list PH casino apps |
| Tight prepaid mobile data plan (Smart GigaLife / Globe GoSurf) | APK | Lower KB/spin saves ₱1 per ~5 MB of data |
Pros and cons
Pros — APK install
- 15% longer mobile sessions before thermal throttle bites.
- Lower KB/spin — meaningful for prepaid mobile data plans.
- Cleaner spin-button feedback at the 25-minute mark.
- Local asset cache means mid-session sprite reload (e.g., bonus-buy modal) is instant.
Cons — APK install
- Requires “Install unknown apps” permission for the source — some Filipino players are hesitant.
- 22–28 MB initial download eats prepaid data on the install itself.
- Updates are not automatic — player has to side-load each new build.
Pros — browser play
- Zero install friction — tap and play.
- Always serves the latest provider build.
- No permission prompts.
Cons — browser play
- 10–15% sustained CPU overhead from the browser shell.
- Higher KB/spin on every paid spin.
- Sessions thermally throttle sooner on mid-range Android handsets.
FAQ
Does APK install change my Sugar Rush or Sweet Bonanza RTP?
No. RTP is determined by the Pragmatic Play math sheet on the operator’s back end — not by the rendering pipeline. Both Sugar Rush and Sweet Bonanza ship the high-build math (96.51% / 96.50% theoretical) on KAYU’s bench. APK install changes the experience of the same outcome, not the outcome distribution.
Is the APK install safe?
The APK is the operator’s signed Android package. As long as you side-load from the operator’s own URL (not a third-party mirror) the package is the same build the operator audits. Verify the installer hash against the operator lobby’s download page before granting install permission.
Why is the PWA only 5 MB but the APK is 28 MB?
The PWA service worker fetches sprites and audio on demand and caches them per session; the APK ships the entire bundle up front. Long-session players amortise the APK install cost in 1–2 sessions of saved per-spin data; casual players never recoup it.
Sugar Rush mobile vs Sweet Bonanza mobile — which is the more mobile-friendly Pragmatic title?
Sugar Rush has the smaller asset bundle and the lighter cascade animation per win, so it holds 60fps slightly longer on Cherry Mobile / Realme C55-class handsets. Sweet Bonanza’s tumble + multiplier-bomb overlay is the heavier render. For pure mobile session quality, Sugar Rush; for ceiling chase, Sweet Bonanza (21,100× vs 5,000× ceiling).
Does the PWA work offline?
The slot itself does not run offline because every spin posts back to the operator’s game server for the RNG outcome. The PWA can render the lobby UI and the previous-session balance offline but cannot accept real-money spins.
