You want to organise a prediction game just for your employees? A good idea, we think, because a prediction game is a nice way to have a small social event with your colleagues besides work that doesn't cost much time. A quick moment to predict the Premier League on Friday. And on Monday, you can talk about the weekend over coffee.
Since the number of participants should be limited, it is best to ask for the staff number or similar data in addition to the player's name. This will ensure that only employees play. Each time you register, you will receive a message with this data and can quickly check whether the registration is correct.
But don't worry: Unwanted registrations rarely occur, because the name of the prediction community must already be known if someone wants to register. And you send the link to the community by invitation only to your employees.
