Asterism is a calm hex logic puzzle where you never have to guess. Each number counts the stars around its hex, like Minesweeper, but a solver checks every puzzle so logic alone solves it, and each solved puzzle turns into a constellation. Seven hand-made worlds each add a new rule, there is a new puzzle every night, and Deep Sky holds 4,000+ generated puzzles you pick by rule and depth. Hints explain the reasoning. Android, free to start, no ads, works offline.

Hi Product Hunt! I'm Tobias, and I made Asterism on my own.
It's a logic puzzle on a hex grid: each number counts the stars around it, a bit like Minesweeper, but you never have to guess. Every puzzle is checked by a solver before it ships, and if the solver would ever need a guess, the puzzle doesn't make it into the game. When you solve one, its stars join into a constellation in your sky atlas.
What's inside: seven hand-made worlds, each adding a new rule (line clues, clusters, mirrored skies, paired stars, nebulae), a new puzzle every night that gets harder towards Sunday, and Deep Sky, an endless mode of generated puzzles you pick by rule and depth. Hints don't just reveal a hex, they explain the reasoning.
The part I enjoyed building most was the generator. Rating a puzzle by its hardest step turned out to be a poor measure of how it feels, so it measures how many moves you could prove at each moment of the solve instead, and tunes which clues are shown until that feels right.
No ads, no timers, no account needed, and it works offline. The first two worlds, the nightly puzzle and part of Deep Sky are free; one purchase opens the rest. Android only for now.
I'd love your feedback, especially on difficulty and on the hints. I'll be here all day to answer questions.
