## What is Constellations?

Zen Star Sudoku: place the stars, reveal your constellation.

Constellations is a logic puzzle game inspired by Sudoku, also known as "Star Battle", "Two Not Touch", "Queens" or "Starstruck": your job is to find the right cell for each star, row by row, column by column, region by region – without ever letting one star touch another. Every puzzle has a unique solution that can be found through pure deduction – no guessing required. As a reward, each solved level reveals its own constellation, drawn just for you.

A relaxing, stress-free puzzle game with no timer and no pressure. Perfect for unwinding before bed, during a break or on the go, with an unlockable Speedrun mode for those who love a challenge. Discreet, non-intrusive ads, so you can stay focused on your sky.

HOW TO PLAY

Exactly one star per row, per column and per colored zone.
Two stars can never touch, not even diagonally.
A single tap places a cross to rule out a cell; a double tap places a star there.
Every level starts with a free hint: a star already placed to get you going.
A few mistakes are allowed in each level before you have to start over.

ZEN MODE BY DEFAULT
No forced timer and no score constantly on screen: just you, the grid and your reasoning, at your own pace.

SPEEDRUN MODE
Want more thrills? Race against the clock and try to solve each grid as fast as you can.

BLINDFOLD MODE
A brand-new way to play: no more crosses to rule out cells, only your deduction guides where the stars go.

ENDLESS PROGRESSION
Hundreds of sudoku-style puzzle levels, from the simplest grids to the largest ones for seasoned strategists – the difficulty grows with you.

DAILY CHALLENGE & LOGIN STREAK
A new puzzle every day, and rewards that pile up as long as you keep coming back.

YOUR OWN SKY
Revisit solved levels at any time from the collection, and rediscover every constellation you have revealed.

LEADERBOARD & ONLINE SAVE
Compare your progress with other players and pick up your game on any device.

No connection required to play, no time pressure: just you, your eye for detail, and a sky to piece together, star after star.

A free-to-download, addictive brain-teaser, perfect for fans of Sudoku, Star Battle, puzzles and zen brain-training games.
