This game plays like Reverse Radial Ultra Cross. You have to start at the four corners and move closer to the center, marked in chartreuse. The chartreuse square must be left last to associate.
The difference is that there is a smaller Radial Word Association board (which cannot be started until the center square is filled) starting with the same word in the chartreuse square.
This is the inverse of Expansive Grid.
