Rules and partial scoringEdit
For puzzles 3-5, images given were the same, but solvers were required to find two images that:
(3) were identical. (One can be obtained from the other by rotation and translation only.)
(4) were mirror images. (One can be obtained from the other by flipping it once and then rotation and/or translation.)
(5) were complements of each other. In other words, they can be placed one on top of another (using only rotation and translation, no flipping) in such a way that together they form a complete picture – their vertices will coincide and each pair of vertices will be connected by a line in exactly one of the two objects.
Alternatively, see the example on the right.
For puzzle 14, the goal was to find 3 words. Each found words were worth 10 points.
