This fiendish idea makes everyone think that they are working together however there is one person who is DISCRETELY trying to make the group lose each trial. Will they discover who? Some of the crafty trials are testing your mental strengh, others are physical and some are just hillariously good fun.
It's a fantastic way for managers, bosses and employees to learn more about each other in one single day, than a lifetime inside an office!
