The challenge
Device fragmentation and a weekly content cadence were outpacing manual QA.

Every new event risked breaking a device the team had not tested.
Heroes of Fortune ships content weekly across hundreds of Android and iOS device variants. The QA team could only manually verify a handful of reference devices per release, so regressions on older Android builds and edge-case iOS hardware were slipping into production and surfacing through player support tickets instead of pre-release testing.
Continuous coverage across the device matrix.
ManaMind was integrated into the release pipeline and ran parallel sessions across a representative set of Android and iOS devices, replaying core gameplay loops, store flows, and event-specific content for every build.

3 representative findings.
A small slice of the bug pile, ranked by severity. Every finding shipped with reproduction steps and evidence attached.
Purchase confirmation hangs on older Android devices
On Android 10 devices with limited memory, the purchase confirmation overlay failed to dismiss after a successful transaction, leaving players unsure whether the purchase had completed.
Event banner overflows on smaller iPhone screens
The new seasonal event banner overflowed the layout on iPhone SE-class screens, hiding the call-to-action button and blocking entry into the event.
Frame drops in the boss arena on mid-tier Android
A specific particle effect in the new boss arena caused sustained frame drops on a cluster of mid-tier Android devices. Reproduced consistently across multiple runs.
The numbers, before and after.
| Metric | Before | After | Delta |
|---|---|---|---|
| Devices tested per release | 6 | 30+ | +5x |
| Critical bugs caught pre-release | Reactive | Pre-release | Shift left |
| Player-reported crash rate | Higher | Lower | Reduced |
| QA time per release | Days | Hours | Faster |
“ManaMind gives us coverage we could never reach by hand. We can ship weekly content with confidence that the experience holds up across the device range our players actually use.”
