Sudoku Quad Samurai

Take Sudoku to a whole new level with Sudoku Quad Samurai.

LEARN WHILE YOU PLAY

Sudoku Quad Samurai does more than reveal the next number.

The Hint and Solution Walkthrough systems can explain the logical technique behind a move, including techniques ranging from simple singles to advanced Sudoku strategies. This makes the game suitable both for experienced Sudoku players and for anyone who wants to learn how difficult puzzles can be solved logically.

DESIGNED FOR LARGE PUZZLES

A 13-grid Sudoku cannot fit comfortably on a phone screen at full size. The interface is therefore designed specifically for large puzzles.

Zoom in for precise number entry, pan naturally across the puzzle, use the mini-map to see your current position, or jump directly to one of the 13 component grids with the Puzzle Navigator.

FREE DAILY PUZZLE

You can play a randomly selected Daily Puzzle for free.

If you start a puzzle and do not finish it, your progress is saved and you can continue it later. Daily puzzles do not accumulate: you always continue your unfinished puzzle before receiving a new one.

FULL ACCESS

Unlock Full Access with a one-time purchase to gain unrestricted access to all 1,000 puzzles, choose your preferred difficulty and play without the Daily Puzzle restriction.

No subscription is required.

Whether you want a relaxing logical challenge or an enormous multi-grid Sudoku that can keep you thinking for a long time, Sudoku Quad Samurai offers a very different Sudoku experience.
