Question types: Which domino is missing?

Rule: Domino sequences

Follow the left halves and the right halves separately: each goes up or down by a fixed number.

A half has 0 to 6 dots and counts round: after 6 dots comes 0 again.

Example: Left halves 1, 2, 3, ?; right halves 6, 4, 2, ?: the missing domino is 4 | 0.

Watch out: Don’t add the two halves together: each half has its own rule.
