Stars (Inkwell Games)

Stars is one of the daily logic puzzles on Inkwell Games, beside Loopy River and Mosaic, pitched as a daily puzzle for your left brain. Each day there is one grid, the same for every player, divided into black-bordered regions.

The rule is the two-star version of Star Battle: every row, every column and every region needs exactly two stars, and stars cannot touch each other, not even diagonally. You place stars and mark impossible cells with an X until the grid is complete.

An interactive tutorial teaches the key deductions: a three-cell region that needs two stars must have them at both ends, cells around a star can be crossed out, three empty cells in a row needing two stars rule out the middle one, and a 2x2 box can hold at most one star.

It suits fans of Queens and one-star Star Battle who want a harder daily step up.
