Yes, that is possible and our employees will be happy to do it for you. Please actively address the game masters that the birthday vest function should be used. Since almost all of our groups celebrate birthdays, it would be too long a process to set it up for all the birthday kids before each round. Once set, the vest will play a birthday song prior to game start and will glow in all special colors throughout gameplay, granting unique bonuses throughout gameplay. In this way, everyone in the area knows who the birthday child is and of course it fills up especially on the most important day of the year.
