Star Battle is an object placement puzzle (with some familiar features from more common puzzles like Sudoku and Battleships) that has its own intriguing logic to deduce. This week I've made two Star Battle puzzles for you to enjoy. What I'd call the "SB" star battle is easy, while the "4J" puzzle is a little bit trickier (but hardly impossible; it's more like a medium).
Rules: Place stars into some cells in the grid so that each row, column, and region contains exactly two stars (in the example, just one star). Stars cannot be placed in adjacent cells, not even diagonally.
