Play your way

A kinder kind of brain teaser

Clear rules, meaningful choices, and just enough personality to make every board feel alive.

Pure, satisfying logic

Place one critter in every row, column, and colored region. Every board has one unique solution.

Designed for more players

Adjust double-tap timing and choose color-vision-friendly, high-contrast, or monochrome palettes.

Meet your critter crew

Solve with River Otter, Highland Cow, and more collectible personalities as your campaign grows.

Three simple rules

One per row. One per column. One per region.

And critters cannot touch—not even diagonally. From there, every mark is deduction.

Coming soon

StarDoku is getting ready to launch.

We are preparing the first release for iPhone, iPad, and Android.
