Instructions
Take note of a common shape in the first three boxes. For example, in security level 2, sequence B, the dots are arranged in a "7" pattern and rotate around the edges of the grid in a clockwise formation. To complete this puzzle, rotate the pattern 90 degrees clockwise from the last position.
Determine if the sequence is moving through the grid or rotating through the grid. In security level 3, sequence A, the dots on the second line are gradually moving down to the fourth line. To complete the sequence, add the final dot to the fourth line.
Recognize when two patterns are going on simultaneously. In security level 6, sequence A, the three lines in the bottom right are turning clockwise along the edges of a 3-by-3. At the same time, the dot on the left is descending down the leftmost column.
