Why is it Called Two Not Touch?
In standard 10x10 Star Battle, every row, column, and region must contain exactly two stars. The most critical constraint—and the one that players frequently trip over—is that no two stars may touch, not even diagonally.
U.S. newspapers and puzzle syndicates began calling it “Two Not Touch” as a descriptive name to make the rules immediately obvious to casual solvers.
