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
Pattern Rule
Two elements (X and O) converge from opposite edges toward center, cross, then diverge to opposite edges. Symmetric sequence: 1 = X top-left + O top-right 2 = X middle-left + O middle-right 3 = both center (overlap) 4 = O middle-left + X middle-right (positions swap) 5 = O top-left + X top-right (continue outward) 6 = back to center overlap (both center again, completing cycle).
Explanation
Option C shows both elements in center overlap, completing the convergence-fusion cycle. Option A shows X top-left and O top-right — that is frame 1, one step before overlap. Option B shows one element at center and one at edge, breaking the symmetric convergence pattern — both elements move in sync. Option D shows X top-left and O middle-left — both on same side, violates the symmetric left-right alternation. Option E shows X middle-left and O middle-right — that is frame 2, one step before center overlap, not the full convergence.
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)
