Core Syntax & Patterns
The 'AND' Rule
Object must be [property 1] AND [property 2].
Use this when a clue gives you two things to look for at once. The object must have both things.
The 'NOT' Rule
Object is NOT [property].
Use this to cross out wrong answers. It tells you what something isn't.
The 'Position' Rule
Object is [first, next to, last].
Use this to put objects in the right order or place. It tells you where things go.
