Cohort-baseline mobile performance.
Crash Games on mobile
The Crash Games multiplier-display animation requires continuous frame-rate accuracy for the cash-out timing decision. iPhone 15 Pro renders the multiplier display at 60 fps on Wi-Fi 802.11ax. Touch input for the cash-out tap registers in roughly 90 milliseconds.
On 4G LTE, occasional frame drops during the rapid-multiplier-rise phase may compromise cash-out timing precision. Wi-Fi 802.11ax or 5G recommended for Crash Games sessions.
The crash event animation is dramatic and visually compelling on phone screens. The structural mobile consideration: the multiplier display reads cleanly on 6.1-inch and 6.2-inch screens but is more comfortable on larger displays.
Slots on mobile
Slotmill, 3 Oaks, Evoplay, and Slotopia titles render at 60 fps on iPhone 15 Pro and Pixel 8 over Wi-Fi 802.11ax. Touch latency held at roughly 110 milliseconds.
Table Games on mobile
Blackjack and Roulette render at 30-60 fps on phone screens. Card-deal and roulette-spin animations operate smoothly on Wi-Fi.
Scratch Games on mobile
The scratch-and-reveal gesture operates smoothly on touch screens. Each card resolves in roughly 5-10 seconds.
Instant Win on mobile
Instant Win mini-games render quickly and resolve in roughly 5-15 seconds per play. Cohort-baseline mobile performance.
The Skrill mobile flow
Skrill requires existing Skrill account. End-to-end roughly 22-42 seconds depending on Skrill authentication speed.
The Gift Cards mobile flow
Gift Card entry requires manual card-number-and-PIN transcription (typically 16-digit card number plus 4-8 digit PIN). End-to-end roughly 35-60 seconds depending on input speed.
The Discover purchase flow
Discover card-direct entry via iCloud Keychain autofill processes in roughly 12 seconds. Without autofill: roughly 35 seconds.
No push notifications
SunSpin.us does not request iOS Safari Push Notification or Android Chrome Notification permission.
No PWA shell
Safari Add to Home Screen produces a launcher shortcut.
