Play more Star Battle
Pick a size and a level and play as many Star Battle grids as you like. Sizes run from 8x8 to 10x10 with one star per unit, plus 10x10 with two stars; the level is the hardest technique a puzzle needs, so a Hard 8x8 is harder than an Easy 10x10.

Loading ยท the grid and its level
(a small spoiler)
Checked: exactly one solution, reachable by logic. The level is the hardest technique our solver needed, not the grid size.
Settings
Rule breaks (two stars touching) always show in red. "Show mistakes" also marks cells that disagree with the solution.
Bigger is not the same as harder
A larger grid mostly adds steps, not difficulty. What makes a puzzle hard is the kind of deduction it forces: an Easy grid falls to the basic rules, a Medium one needs a squeeze (a star here would starve a region), a Hard one needs regions counted across several rows. The table shows how this plays out in our bank.
