The world’s favorite logic puzzle — now personalized with names, favorites, and fandoms!

📖 Product Description

Sudoku has entertained millions worldwide — but with Niji, it becomes personal. Instead of just numbers, your Sudoku puzzles can feature names of friends, family, teachers, favorite foods, or fandom characters (Harry Potter, Avengers, Pokémon, and more).

The rules are the same: fill the grid so that no row, column, or box contains a repeat. But now, every puzzle feels like it was designed just for you.

With grid sizes (4x4, 6x6, 9x9), levels (Easy, Medium, Hard), plus timers, hints, and rewards, Sudoku is fun and brain-boosting for all ages — from kids building logic skills to adults keeping their minds sharp.

Available in both digital mode (with confetti celebrations and points) and printable black & white books for screen-free play.
