Why It Exists
The goal is to make small logic puzzles easy to start, fair to solve, and worth returning to. The site focuses on fast loading, clean puzzle controls, mobile-friendly play, and useful explanations for people discovering Star Battle or related grid puzzles.
How Puzzles Are Generated
Star Battle boards are generated in the browser and checked against a solver. A board is accepted only when the solver finds exactly one valid solution.
Keeping Puzzles Free
All puzzles, practice modes and tools remain free. After enjoying the content, you can optionally leave a one-time tip by card through Stripe or with a supported cryptocurrency. Tipping is not required and does not unlock extra features. Open Support this project in the footer to choose an amount or a wallet network.
