Hello US!

We’re a Seoul-based startup, designing and making TheSudoku.

Thanks!

Since this summer, I’ve been getting so many DMs from friends in the U.S. asking if they can get The Sudoku 🇺🇸

Thank you so, so much for showing love to our reimagined version of Sudoku — made with our own little vibe 🩵

So, we go US!

So, we’re going to US!

Can’t wait to see you soon 💛

FAQ

💸 What is the return policy?
