The passing rate for Crossy Road was 88.3% among the hundreds of devices tested, which is superior to the average index compared to the whole industry and nearly close to optimal ranges. A high compatibility rate improves players’ game experience and is helpful for game retention rate.

The failing phones usually failed during the installation and tutorial section and in rare cases, start-ups. The main problem occurring during the tutorial section, (6.5% device failure rate) was a bug creating crashes and blank screens.

Comparison Among Devices
