Challenge Level

28 points have been marked on the axes below.

The points mark the vertices of eight hidden squares.

Each of the four red points is a vertex shared by two squares.

Each square shares exactly one vertex with another square.

Once you've found them all, take a look at the grid below:

This time, there are $34$ points marking the vertices of ten hidden squares.

There are $6$ red vertices, which are shared by two squares.

All of the squares share at least one vertex with another square.
