Session length

Summary

We can be confident that session length, especially the proportion of long sessions, has decreased.

As with staking, the changes could undermine the impact of the game design changes if those who reduced their spin speed subsequently changed their behaviour and increased their session length to the extent that they were no longer gambling within their intentions or means.

As highlighted in the outcomes section of this report, the proportion of sessions lasting over 60 minutes reduced from 7.8 percent in the six months prior to the changes to 6.9 percent in the six months post-changes. Amongst this sample of gambling businesses, this sample comprised over 430 million sessions.
