Cyberchase: Switches, Levers, and Buttons
Jackie, Inez, and Matt have to use one combination of switch, lever, and button in order to obtain the crystal. They create a tree using the Squak Pad to display all of the possible combinations and try each one. When none of them work, Delete unintentionally tells them that there is a hidden brown button. They add the brown button to the possible combinations and find the correct combination.
