Hello SG!

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 SG asking if they can get The Sudoku!

Thank you so, so much for showing love to our reimagined version of Sudoku β€” made with our own little vibe 🩡

So, we go SG!

So, we’re going to SG!
