Haunted Crypt on Mobile

Haunted Crypt streams straight to your phone in HTML5 — no app store, no install, tap and the crypt opens.

Playing on your phone? The Haunted Crypt gameplay guide walks through the controls.

Device Compatibility

The 5×3 grid renders cleanly on Safari, Chrome, and Firefox across iOS and Android.

First load pulls the vampire assets in about four to seven seconds on 4G; every spin after that is near-instant.

Excellent

iPhone 15/16, Galaxy S24, Pixel 8 Pro

Locked 60fps. Seven-tumble chains and frame lightning stay razor-sharp. Roughly 8-10% battery an hour.

Good

iPhone 12/13, Galaxy A54, Pixel 6a

Mostly 60fps with brief dips when a long cascade lights every frame at once. About 10-12% an hour.

Playable

Galaxy A14, Redmi Note 11, iPhone 8

35-50fps. Frame glow effects thin out, but the Tumble math is untouched. Around 12-15% an hour.

Shut other tabs, clear the cache, and do the first load on Wi-Fi.

Turn off battery saver and clear background apps before a session.

Flick off the mute switch; iOS Safari waits for your first tap before it plays audio.

Let the current tumble finish resolving, then try again — a quick rotate resets stuck input.
