## What is Huedoku?

Huedoku is Sudoku reimagined in colour. Instead of the digits 1–9, you place nine hand-picked pastel hues so that every row, every column, and every 3×3 box contains each hue exactly once. Same satisfying logic — a calmer, more tactile way to play.

A PUZZLE FOR THE SENSES
• No numbers, ever — nine soft hues replace the digits
• Warm, considered palette designed to soothe, not shout
• Smooth, gentle animations and a quietly satisfying confetti celebration when you win

FOUR DIFFICULTY TIERS
• Gentle — ease in with plenty of clues
• Calm — a little more thinking required
• Focused — for steady, deliberate solving
• Deep — sparse clues and advanced deductions for experts

THOUGHTFUL TOOLS
• Notes mode — pencil-mark candidates in a mini-grid inside each cell
• Hint system — fills the most logical next cell when you're stuck
• Unlimited undo — explore freely, step back anytime
• Conflict detection — strict, lenient, or off; your choice

MADE FOR EVERY EYE
• Optional patterns overlay adds a distinct shape to each hue, so the game plays beautifully for colour-blind players too

PLAYS ANYWHERE, ANYTIME
• 400 puzzles bundled in — 100 per tier
• Fully offline: no internet, no account, no sign-up
• Your in-progress game saves automatically — pick up right where you left off

PRIVATE BY DESIGN
• Pay once — no subscriptions, no in-app purchases
• No ads, ever
• No accounts, no sign-up
• No data collected — everything stays on your device

Whether you have five minutes or fifty, Huedoku turns a moment of logic into a moment of calm. Place the hues, find your flow.
