Adjacent Face Identification
Adjacent Face Identification problems require you to determine which faces of a dice are next to each other (adjacent) and which are opposite. You will use the given information about a standard dice (opposite sums to 7) or from two different views of a custom dice to deduce the relationships.

Introduction to Adjacent Face Identification
Adjacent Face Identification problems require you to determine which faces of a dice are next to each other (adjacent) and which are opposite. You will use the given information about a standard dice (opposite sums to 7) or from two different views of a custom dice to deduce the relationships.
Prerequisites
How to Solve Adjacent Face Identification Problems
Step 1: For a standard dice, remember the fixed opposite pairs: (1,6), (2,5), (3,4).
Step 2: Identify the given face on the dice.
Step 3: The faces adjacent to it are the four faces that are not its opposite.
Step 4: For custom dice problems, compare two different views of the same dice.
Step 5: Identify a common face appearing in both views. The faces adjacent to this common face in each view are its neighbors.
Step 6: The faces that are adjacent to the common face in both views are also adjacent to each other.
Step 7: Conclude which faces are adjacent to the given face.
Example Problem
Example: On a standard dice, which faces are adjacent to the face with 3 dots? Solution: Step 1: Standard dice opposite pairs: (1,6), (2,5), (3,4). Step 2: The face opposite to 3 is 4. Step 3: The remaining faces (1, 2, 5, 6) are all adjacent to 3. Answer: 1, 2, 5, and 6.
Pro Tips & Tricks
- On a standard dice, any face that is not the opposite is automatically adjacent.
- If you see two different views of a dice, the faces that are next to a common face are neighbors.
- The face that appears in two different views is often the key to unlocking the entire configuration.
- If face A is adjacent to B and C, it doesn't automatically mean B and C are adjacent to each other.
- Draw a 3D cube skeleton and label the faces as you deduce them.
- In a custom dice, the opposite pairs are fixed but can be non-standard.
