Nariman Number Nebula
Cosmic star lanes and constellation routes. The original home world.
The World Atlas
Change the feeling.
Change the feeling.
Keep the logic.
Sudoku Cosmos treats worlds as visual voices for a shared puzzle language. They are not different rule systems or separate save files; the player’s progress belongs to the profile, while the atmosphere can change around the same run.
02◈
Neon Circuit
A live arcade district where each clean solve relights the skyline.
03◇
Stone Age Sigils
Ceremonial locks, relic murals, and a gentle excavation rhythm.
04◉
Ocean Pulse
Luminous reef currents that turn row and column flow into a dive.
05✦
Zen Bloom
A quiet garden of petals, control, and ceremonial finishes.
The world rule
Style earns its place only when the player stays oriented.
The Android design keeps the board central. Worlds change colour, glyph tone, feedback language, and level-map atmosphere; they do not force a new rules tutorial or split the player into separate progression systems.
One profileClears, unlocked stages, and level progress remain attached to the player rather than a visual skin.
Three board viewsWorld, Comic, and Classic presentation options provide fast control over the look without abandoning the active run.
Five standard worldsNariman Number Nebula, Neon Circuit, Stone Age Sigils, Ocean Pulse, and Zen Bloom form the standard world rail.
The sealed sixth route
Cipher is a case archive, not another skin.
Unlike the five standard worlds, Cipher has its own episode progression, evidence cabinet, and fictional noir case language. It sits beside the world rail as a distinct investigation track.
