Participant 1

Initial description: The light grey squares remain the same from test input to test output. In the test output, the black squares become red in every space with a corresponding grey square at the top and on the right.

Final description: The light grey squares remain the same from test input to test output. In the test output, the black squares become red in every space with a corresponding grey square at the top and on the right.


Attempt 1: Correct

Participant 2

Initial description: Red boxes are placed where the grey boxes coordinates intersect

Final description: Red boxes are placed where the grey boxes coordinates intersect


Attempt 1: Correct

Participant 3

Initial description: A red box is placed where the grey lines would intersect along the grid.

Final description: A red box is placed where the grey lines would intersect along the grid.


Attempt 1: Correct

Participant 4

Initial description: The same number of red squares as grey squares to the right

Final description: The same number of red squares as grey squares to the right


Attempt 1: Correct

Participant 5

Initial description: Fill in orange on every square that the gray squares would intersect with each other if they extend out.

Final description: Fill in orange on every square that the gray squares would intersect with each other if they extend out.


Attempt 1: Correct

Participant 6

Initial description: if each grey square where the end of a line, extend them out. wherever these imaginary lines would meet, turn the square red.

Final description: if each grey square where the end of a line, extend them out. wherever these imaginary lines would meet, turn the square red.


Attempt 1: Correct

Participant 7

Initial description: The rule is to have a red square where the grey squares would intersect if they were extended, but without extending them.

Final description: The rule is to have a red square where the grey squares would intersect if they were extended, but without extending them.


Attempt 1: Correct

Participant 8

Initial description: The grid can be viewed as an X and Y axis. Where they would intersect, those blocks are turned red.

Final description: The grid can be viewed as an X and Y axis. Where they would intersect, those blocks are turned red.


Attempt 1: Correct

Participant 9

Initial description: Gray boxes are used as a guideline. Fill any box with red that intersects.

Final description: Gray boxes are used as a guideline. Fill any box with red that intersects.


Attempt 1: Correct

Participant 10

Initial description: Add red squares on the grid where the grey squares would meet.

Final description: Add red squares on the grid where the grey squares would meet.


Attempt 1: Correct

Participant 11

Initial description: This is difficult, because none of the tiles are displaying properly here. But the best I can figure out when I try to reassemble them in my head, maybe the red vertical squares show where the lines extending from the gray dots intersect?

Final description: So it looks like the red squares show where the lines extending from the gray squares intersect. (I missed the left row on the previous attempt.)


Attempt 1: Incorrect
Attempt 2: Correct

Participant 12

Initial description: It looked like they were adding plus crunching together

Final description: they added blocks each round


Attempt 1: Incorrect
Attempt 2: Incorrect
Attempt 3: Incorrect

Participant 13

Initial description: imagine the gray extends each way, where they would intersect should be red

Final description: imagine the gray extends -- where they intersect, should be red


Attempt 1: Incorrect
Attempt 2: Correct

Participant 14

Initial description: Wherever the gray squares "align" in the test input, a red square is placed in the example output.

Final description: Wherever the gray squares "align" in the test input, a red square is placed in the example output.


Attempt 1: Correct

Participant 15

Initial description: Color red wherever gray squares would overlap in a line.

Final description: Color red wherever gray squares would overlap in a line.


Attempt 1: Correct

Participant 16

Initial description: I matched the red boxes with the gray boxes

Final description: I matched the red boxes with the gray boxes


Attempt 1: Correct
