## Description

Every hint explains the technique — what it is, why it works, how to spot it next time. 80+ techniques, a daily challenge, and a calm, ad-free board.

Most sudoku apps just hand you the answer. This one teaches you to find it yourself.

WHY IT'S DIFFERENT

Hints that teach
Open a hint and you don't just get the next number — you get the technique behind it: what it is, why it works, and how to spot it next time. Reveal it step by step, so you decide how much help you want.

80+ techniques, explained
From your first Naked Single to X-Wing, Swordfish, Y-Wing, Skyscraper, and AIC/ALS chains — every technique comes with a clear card: what it is, why it works, how to find it, and a worked example you can replay.

A daily challenge
One hand-picked puzzle a day — the same for everyone, everywhere.

Curated, uniquely-graded puzzles
Five difficulties from Easy to Master. Every puzzle is validated for a single solution and graded by the hardest technique it needs — pure logic, never guessing.

Step-by-step replay
Watch any puzzle solved one logical step at a time, and see exactly where each technique applies.

Calm and focused
A clean, distraction-free board. No banners, no pop-ups, no clutter — just you and the logic. Play fully offline.
