ProveSource is a third-party app that we've installed on our website to track and display new visitors and customers in real-time.
Each notification has been verified by ProveSource.
It's one of the ways that we validate what we're doing to build trust with website visitors and existing customers.
ProveSource has been designed to be a fairly un-invasive tool and you can close the notifications by clicking the "x" on them.
We will never show you these notifications when you come to play the game, as we know that you'll want to be fully focused on the task at hand!
