Interaction & Fusion

Two or more elements interact — they merge, overlap, repel, or transform upon contact.

Understanding this pattern

Interaction patterns involve elements that change when they meet. Two shapes approaching each other might fuse into a combined form, or overlapping areas might disappear (XOR logic). These are rare but high-difficulty patterns that test your ability to predict the result of element collision.

Example Question 1

Interaction & Fusion q02_convergence_fusion
Question 2 Options A B C D E
Correct answer: E

Pattern Rule

The hollow circle and X follow mirrored paths toward the centre. They overlap there, continue past each other to exchange sides, and then return to the centre, where they merge again.

Explanation

Option E is the only choice that applies this rule to the next panel. Every other choice stops, reverses, skips, or misaligns at least one part of the pattern.

Example Question 2

Interaction & Fusion q02_convergence_fusion
Question 2 Options A B C D E
Correct answer: A

Pattern Rule

The hollow circle and X follow mirrored paths toward the centre. They overlap there, continue past each other to exchange sides, and then return to the centre, where they merge again.

Explanation

Option A is the only choice that applies this rule to the next panel. Every other choice stops, reverses, skips, or misaligns at least one part of the pattern.

Example Question 3

Interaction & Fusion q02_convergence_fusion
Question 2 Options A B C D E
Correct answer: D

Pattern Rule

The hollow circle and X follow mirrored paths toward the centre. They overlap there, continue past each other to exchange sides, and then return to the centre, where they merge again.

Explanation

Option D is the only choice that applies this rule to the next panel. Every other choice stops, reverses, skips, or misaligns at least one part of the pattern.

Example Question 4

Interaction & Fusion q02_convergence_fusion
Question 2 Options A B C D E
Correct answer: C

Pattern Rule

The hollow circle and X follow mirrored paths toward the centre. They overlap there, continue past each other to exchange sides, and then return to the centre, where they merge again.

Explanation

Option C is the only choice that applies this rule to the next panel. Every other choice stops, reverses, skips, or misaligns at least one part of the pattern.

How to spot it

  • Two elements move toward each other across frames
  • Elements appear to combine or cancel where they overlap
  • The total number of elements decreases as frames progress

Common traps

  • Assuming elements pass through each other instead of interacting
  • Misidentifying which element absorbs the other
  • Not recognizing the interaction rule (XOR vs AND vs merge)
