## What is Nanpure?

Nanpure is the cleanest, smartest sudoku experience on iPhone. No clutter. No filler. Just pure puzzle satisfaction, from your first beginner grid to the most demanding expert challenge.

FIVE DIFFICULTY LEVELS
Start easy and work your way up: Beginner, Easy, Medium, Hard, and Expert. Every puzzle is freshly generated, no recycled grids, so there's always a new challenge waiting.

DAILY CHALLENGE
A brand new puzzle drops every single day. Solve it, build your streak, and compete against your own personal best. Miss a day? Browse the full history and catch up anytime.

MAGIC HINT SYSTEM
Stuck? Nanpure doesn't just hand you the answer, it teaches you. The step by step hint system identifies the exact solving technique you need (naked singles, hidden singles, and beyond), highlights the relevant cells, and walks you through the logic. Get better at sudoku while you play.

BRILLIANT MOVES
Land a high impact placement and the game celebrates it. Nanpure recognises skill and rewards it.

LIGHTNING PENCIL
Fill all candidate marks instantly with one tap. Spend your energy solving, not bookkeeping.

BUILT FOR YOUR FLOW
- Auto-save — leave mid-puzzle, pick up exactly where you left off
- Quick Solve — when you're almost done, let the board finish itself with a satisfying cascade animation
- Conflict highlighting — mistakes are caught immediately, before they cascade
- Undo — go back as many steps as you need

BEAUTIFUL & ACCESSIBLE
Light and dark themes. Haptic feedback. Sound effects. Clean, distraction free design that gets out of the way of the puzzle.

PREMIUM — NANPURE PRO
Unlock unlimited hints, Lightning Pencil for free, and an ad free experience with a single upgrade. One purchase, every puzzle, forever.
