To use the GameWall system, you first need to scan a QR code to join the room / playfield running on the display.
You need to provide a nickname, and if prizes are involved, possibly an email address as well, while also accepting the terms of use.
You can then choose whether you want to play a single-player or multiplayer game. Based on your selection, a list of available games/applications appears. After selecting one, you enter a waiting queue. As soon as it is your turn — possibly immediately — the system notifies you on your mobile phone.
At the end of the game, a leaderboard is displayed, and the system may also reward players.
Afterwards, the process returns to the waiting screen (the so-called Lobby Screen).
Of course, it is also possible for a room to continuously run a single application that users can freely join and leave.
