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.
Matt and Jackie have three differently-colored keys and knobs. They need to use one combination of key and knob to open the door. They organize all of the available combinations into a grid of possibilities and calculate that they have 9 total combinations. As they attempt each combination, they mark down which combination was used until they find the working one.
