There is no ideal in nature, but there is harmony between different species, creatures, and so on, so that they complement each other. Therefore, when they say that a couple is ideal, this does not mean that each of the couple is ideal, but that their union is ideal. The Perfect Pair game invites you to solve a puzzle at each level, and at the same time form ideal couples of boys and girls. To do this, you must connect all the faces into a single chain, which should become closed. In this case, the lines should not intersect, and girlish and boyish faces should alternate with each other in Perfect Pair.
