Twinklet is a calm, clever logic puzzle set under a sparkling night sky.

Place one star in every row, every column and every colour area, and never let two stars touch. That's all there is to the rules. Finding where each star belongs is the fun: every puzzle has exactly one answer, and you never need to guess.

LIGHT UP THE SKY
Every level you solve lights one star of a real constellation. Work through 1,000 levels and light all 88 constellations, from Cassiopeia and the Great Bear to Orion and the Southern Cross. Read each constellation's story in the Star Atlas.

HINTS THAT TEACH
Stuck? A hint shows the next sure step and explains why it works, so you learn the reasoning, not just the answer. The first levels guide you step by step, and an illustrated How to Play guide covers every trick.

A NEW PUZZLE EVERY NIGHT
A fresh puzzle arrives every night. Solve it on nights in a row to keep your streak glowing; a weekly streak freeze covers a missed night. Share your result with friends, and turn on an optional reminder if you like.

DID YOU KNOW?
After every win, discover a surprising fact about stars, planets, galaxies and the universe.
