HOW TO PLAY SEQUENCE BUILDER

1. Press START to begin a timed sequence round.

2. Read the five-token pattern with one missing item.

3. Pick the option that completes the sequence.

NUMBER PATTERN EXAMPLE

2 • 4 • ? • 8 • 10

The missing number is 6 because the sequence counts up by two.

Number mode includes steps, drift, squares, doubling and alternating tracks.

SYMBOL PATTERN EXAMPLE

▲ • ■ • ▲ • ? • ▲

The missing symbol is ■ because the pattern alternates.

Symbol mode includes repeats, cycles, mirrors, anchors and visual logic.

LOOK FOR REPEATS

Repeating patterns use shapes or values that return in a predictable order.

Common examples include ABAB, ABCAB, AABBC and anchor patterns.

When unsure, compare the first and last visible tokens.

LOOK FOR STEPS

Number patterns often move by a fixed step, changing step, double or square.

Try checking the gaps between visible numbers before picking an answer.

Alternating-track puzzles may use positions 1, 3 and 5 as one sequence.

LOOK FOR MIRRORS

Mirror patterns read the same forwards and backwards around the centre.

Symbol sequences often hide a visual symmetry clue.

Mixed mode combines number and symbol logic for broader pattern practice.
