Expert Star Battle
Two stars in every row, column and regionTap once to cross out a cell, twice to place a star, three times to clear it. Drag to cross out several at once.
Expert Star Battle gives you 10×10 grids with two stars where you'll get stuck several times: they ask you to count three or four regions at once, look at two rows together or split the stars among 2×2 squares. For players who have mastered the hard level.
How to play: a game solved step by step
This is a 10×10 grid with two stars per row, column and region, like the ones in hard and expert. Use the arrows to step through it: the cells each step talks about are marked, and nothing is guessed. The idea you'll use most: two stars can't go in cells that touch, so a region with little space runs out of room for both.
Step 1 of 21
Column 10 belongs entirely to the mauve region. Its two stars have to be mauve, and the mauve region only has two, so it can't have any outside column 10. The rest of the mauve region is ruled out.
The rules
Every row, every column and every colored region gets the same number of stars: one in the easy and medium grids, two in hard and expert. Two stars can't touch, whether side by side or diagonally. Every grid has exactly one solution.
The levels
Easy (6×6, one star): you solve it by crossing out the cells around each star and seeing which regions fit in a single row. Medium (8×8, one star): asks you to count two regions at once. Hard (10×10, two stars): the classic championship format. Expert (10×10, two stars): you'll get stuck several times, and it asks you to count three or four regions, look at two rows together or split the stars among 2×2 squares.
The hint
The hint doesn't just place the star for you: it shows you the next step and why, and points out the cells that matter. With the arrows in the note you can reread the hints it has already given you.
