About this book
Star Battle goes by several names. The New York Times publishes it as Two Not Touch. Online it is often called Queens. The rules never change: place one star in every row, every column, and every outlined region, and no two stars may touch, not even diagonally.
That is the entire rule set, which is what makes the puzzle worth 160 grids. There is nothing to memorise and no arithmetic. Everything after the rules is deduction.

Common questions
Is Star Battle the same as Two Not Touch?
Yes. Two Not Touch is the name The New York Times uses. Star Battle is the name used in most puzzle circles. Same puzzle, same rules.
How is this different from Sudoku?
There are no numbers and no arithmetic. You place stars using position alone, so the deduction feels different even though both reward careful scanning.
Are the answers included?
Yes, answers in back, four to a page and in the same order as the puzzles.
Can every puzzle be finished with logic?
Yes. Each grid holds one solution, reachable from the regions printed on the page.
