Astra Ignota

Astra Ignota is a minimalist puzzle game set aboard a sentient spaceship drifting between stars. You grow symmetrical galaxies outward from their cores until they fill the board, solving 60 handcrafted puzzles while uncovering a science-fiction story through brief episodes.

Puzzle solving

The game uses multiple grid types and tools that unlock as the story progresses. Its difficulty rises from tutorials to devilish puzzles, and there is no time pressure: solving relies on patience, observation and discovery. The idea comes from Tentai Show, also known as Galaxy, by the Japanese puzzle magazine Nicoli, which created Sudoku.
