How the rule works

The third cell in every row is the first one mirrored: what sat on the left sits on the right, or what was on top is at the bottom. Everything flips at once, the lines along the edge, the symbols in a container, the dots on either side of a line.

A mirroring is not a rotation. A turned L and a mirrored L look different, and the options in such a task often differ in exactly that. Find something that breaks the symmetry, a single line or a dot, and see where it ends up.

Solved example

The bottom right cell is the answer, marked. The explanation below the matrix is the same text the app gives.

Rules in the example

  • The third cell in every row is the first one with the symbols in reverse order.
  • Everything else is the same in every cell.

Level 2 in the app. The same example is shown in the app after a wrong answer on this rule. Rules in the example: Mirroring.

How to recognise it

  1. Compare cell one and three in the first row. Is three a mirror image of one?
  2. Decide the mirror axis: do left and right swap, or up and down?
  3. Mirror the first cell of the last row the same way. Do not confuse it with a turn.
