The star battle puzzle is a placement puzzle: a square grid is cut into coloured regions, and the child places stars so that every row, every column and every region holds exactly the same number of stars — one in the early chapters, two in the later ones — and no two stars ever touch, not even diagonally.
Here it lives under a night sky: regions glow as soft jewel-toned constellations, stars light up with a golden halo when placed, and a finished board draws its own constellation of lines between the stars. 300 puzzles in seven chapters from 4×4 up to 10×10, every one machine-checked to have exactly one solution.
The board marks only a real rule break — two stars touching, one row, column or region with too many — a legal but wrong star looks exactly like a correct one.
How to play
Tap a cell to cycle it empty → star → cross-out mark → empty; the cross is just a player's note and never affects the rules. The first puzzle is a voiced lesson right on the live board, showing which cell must hold a star and why.
Big Undo is always at hand; Restart asks first. A hint button clears one wrong star or lights up one safe cell — never the whole answer.
What your child learns
Star Battle is spatial deduction: a child has to hold three constraints at once — row, column and region — and reason about adjacency, not just counting. 'This region already has its star, so every other cell in it must stay empty' and 'these two cells touch, so only one of them can ever hold a star' are the two moves that carry the whole game, building the same muscle used in scheduling and packing problems later on.
The science behind the games
Every Dad4Kids game is built on one simple truth: children want to play, not study — so we turn learning into a game worth replaying. The method draws on peer-reviewed research in game-based learning, motivation, and how memory works.

FAQ
What are the rules of Star Battle?
Place stars on the grid so that every row, every column and every coloured region holds exactly the same number of stars, and no two stars touch each other, including diagonally.
Does the game show the answer?
No. The board only marks a broken rule — two touching stars, or a row, column or region with too many. A star that is legal but wrong looks exactly like a correct one until the whole grid is finished.
What age is it for?
The 4×4 chapter with one star per line and a voiced lesson suits a six-year-old; the 9×9 and 10×10 chapters with two stars per line are a real challenge for older kids.
Is every puzzle solvable?
Yes: all 300 puzzles were verified by a solver to have exactly one solution.
