What’s New Version 2.1.0
Tidied up the level selection screen: strategy groups are now organized into clear sections, and expanding a group is smoother.
Description
Hintoku teaches sudoku, one strategy at a time. Each puzzle group introduces specific techniques — like X-Wings, Skyscrapers, and chains — with interactive demos before you play. And when you get stuck, hints escalate one tap at a time — from a tiny nudge to a full walkthrough.
Tired of getting stuck on a Sudoku puzzle and having to guess? Wish you could solve even the hardest puzzles with confidence?
Welcome to Hintoku, the Sudoku app designed to teach you. Instead of vague difficulty levels, Hintoku guides you through puzzles grouped by the exact strategies needed to solve them, one step at a time. You will always have the tools you need for the puzzle in front of you.
Key Features:
LEARN EVERY STRATEGY: Progress through a structured path, from basic techniques to advanced strategies like Skyscraper and X-Wing. Each new puzzle group teaches you the controls and the logic with interactive demos before you play.
A TRULY INTELLIGENT HINT SYSTEM: Never feel lost again. Our unique hint system guides you, it doesn't just give you the answer.
It starts by showing you the difficulty of the easiest next move available.
Need more? A tap reveals the strategy name and a specific tip to guide you.
If you're still stuck, get a full, step-by-step visual guide right on your current puzzle to see how the logic works.
SMART, EFFICIENT CONTROLS: The interface is designed to be fast and intuitive.
There is no toggle needed between modes. Simply tap a number to add or remove it as a candidate, and long-press to confirm it as the solution.
POWERFUL SOLVING TOOLS:
Use Spotlight Mode to instantly see all instances of a number, making it easier to spot patterns and solve the puzzle faster.
PLAY YOUR WAY:
Enjoy a clean, focused interface available in both Light & Dark modes to suit your preference, day or night.
Whether you're a beginner wanting to build confidence or an experienced player eager to master the most complex strategies, Hintoku is your perfect companion.
Download Hintoku today and stop just playing Sudoku—start mastering it!
