Stelline
Star Battle-style puzzles, each proven to have one solution
A calm Star Battle-style logic game for iPhone. Every board is generated on the phone and proven by an on-device solver to have exactly one solution, so play is unlimited and works fully offline. A deduction engine grades each board and explains hints one logical step at a time. No ads, no account, nothing leaves your phone. Free until 1 October, then USD 1.99, paid once.
Hello Product Hunt. I am an independent developer (Andelis Studio, a one-person studio) and Stelline is my Star Battle-style puzzle game for iPhone: one queen, or two stars, in every row, column and region, and no two touching.
What is different: nothing comes from a server. Boards are generated on the phone, an exact solver proves each one has exactly one solution before you see it, and a seventeen-technique deduction engine grades it and powers hints that teach the next logical step instead of giving the answer. Unlimited boards, fully offline. No ads, no account, no network code; Game Center is optional and off by default.
There is a shared daily board, board links you can send to a friend (they open in any browser), full VoiceOver support and a colour-blind mode. Version 1.3 added German, Spanish, French, Italian, Japanese and Brazilian Portuguese.
It is free until 1 October, then USD 1.99, paid once.
