Expansive Grid Game #6: "Physical cosmology"
The rules are like the radial game; a word starts in the center of the grid, and words expand out of the middle. Unless the word is in a straight line from the center (or from a branch's purple square), it must associate with two words.

The difference is that an Expansive Grid Game must branch smaller grids at the four corners. The four corners are marked purple.

The purple squares in the main game and corresponding branch must be the same word. (and must be bold)

Game #6's starting word, Physical cosmology, was chosen via Random Article.

Game #5, which started with December 1 and ended with Threesome (branched to Born in the purple), Transphobia (branched to The X-Files), Glitch (branched to IGNITOR), and Don't ask, don't tell (branched to Manchester Transit Authority), is at this link.

Expansive Grid's inverse is Inversive Grid, while its reverse is Condensive Grid. Explosive Grid is similar, but with full-fledged Radial games for its branches. The polar opposite is Reversive Grid.
