- Choose the answer that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: E
8 layers. The punch unfolds to 8 holes with symmetry across the vertical midline, horizontal midline, AND the third fold line (y=0.75).
- Choose the letter that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: D
Two half-folds = 4 layers. Produces 4 holes symmetric across both midlines.
- Choose the letter that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: E
A halving + a corner-fold on the folded rectangle + another halving. Produces 4 holes in a distinct central 2×2 pattern.
- Choose the letter that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: E
8 layers. Unfolds to an 8-hole "corners + center" pattern (complement of Q10's ring pattern) — symmetric across both midlines and the anti-diagonal.
- Choose the answer for which the black dots represent holes in the unfolded paper.
Answer: C
Single diagonal fold = 2 layers. Unfolds to 2 holes diagonally opposite.
- Choose the letter that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: E
8 layers; a corner punch produces 8 holes in two vertical columns — symmetric across the vertical midline, horizontal midline, AND the third fold line at y=0.25.
- Choose the letter that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: A
Single half-fold = 2 layers. Unfolds to 2 holes mirrored across the horizontal midline.
- Choose the answer that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: A
The corner-fold creates a 2-layer region only in the top-right quadrant. The two halvings multiply layers differently across regions, producing a 3-hole asymmetric pattern.
- Choose the letter that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: B
Single anti-diagonal fold = 2 layers. Unfolds to 2 holes mirrored across y = 1 − x.
- Choose the answer for which the black dots represent holes in the unfolded paper.
Answer: A
4 layers; unfolds to 4 holes in the outer columns of the two inner rows.
- Choose the answer for which the black dots represent holes in the unfolded paper.
Answer: E
Two perpendicular half-folds = 4 layers. Produces 4 holes symmetric about both midlines.
- Choose the answer for which the black dots represent holes in the unfolded paper.
Answer: C
4 layers; a corner punch through 4 layers produces holes at all 4 corners of the original paper.
- Choose the answer that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: A
4 layers. Unfolds with symmetry across both the main diagonal and the triangle's median — a rotationally-related pattern.
- Choose the answer that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: B
The small corner-fold creates a 2-layer region in the top-right; subsequent halvings multiply it. The punch lands where the corner-fold layers overlap the quarter-fold layers, producing an asymmetric 5-hole pattern (a giveaway pattern only a careful solver notices).
- Choose the letter that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: B
Anti-diagonal fold + horizontal fold. Unfolds to 3 holes asymmetric across the anti-diagonal — a classic distractor-trap pattern.
- Choose the letter that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: C
Corner-fold creates extra layers in the lower-left. Subsequent halvings produce an asymmetric 5-hole pattern — central 2×2 plus one extra hole in the corner.
- Select the answer that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: B
Two halvings → 4 layers; diagonal fold → 8 layers. Unfolds to 4 holes with symmetry across both midlines and the anti-diagonal.
- Identify the letter that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: D
Two opposing corner-folds + a halving. Produces a 3-hole pattern invariant under 180° rotation — pretty to look at, hard to predict.
- Choose the letter that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: C
Corner-fold creates extra layers only in the upper-left; subsequent halvings redistribute them. Produces an asymmetric 5-hole pattern.
- Choose the letter that corresponds to the image for which the black dots represent holes in the unfolded paper.
Answer: D
Diagonal fold (2 layers) + median fold (4 layers). Unfolds to 4 holes in a rotationally-arranged pattern — symmetric across both the main diagonal and the median.
