## What is Aikui?

Color sudoku, free to play and easy on the eyes.

Solve with nine colors instead of numbers, on a board everyone can read, colorblind or not. No ads. No subscription. Ever.

COLOR YOU CAN TRUST
The default colors are chosen to stay distinct for the common kinds of color blindness, the same approach trusted in scientific figures. Turn on Pattern Mode and every color also carries its own shape, so the board stays readable even when color alone is hard. Accessibility is never behind the paywall.

ACCESSIBLE ALL THE WAY
Full VoiceOver, Dynamic Type, and Reduce Motion support, plus a Differentiate Without Color setting that brings the shapes in for you. And it speaks 50 languages, so the game meets you in yours.

A CALM PLACE TO THINK
No timer, no pressure, no flashing rewards. Just a quiet board, gentle haptics, and a light or dark look that follows your device. Aikui is about depth, not speed.

PLAY YOUR WAY
Cell-first or color-first input, pencil marks, undo, and mistake checks. Four difficulties from Gentle to Hard, drawn from a bundled bank of 10,000 hand-checked puzzles that play fully offline and each have exactly one solution.

DAILY PUZZLE AND GAME CENTER
One shared Daily Puzzle for everyone, every day, with streaks and Game Center leaderboards for mastery, clean solves, and each difficulty.

AIKUI PRO, YOURS FOREVER
One optional purchase unlocks Medium and Hard, the Daily Puzzle, competitive leaderboards, premium color palettes, and board styles. Buy it once and you own it. Gentle and Easy, the colorblind-friendly palette, and Pattern Mode stay free for everyone.

Where color meets calm.

### 1/5 — Jeu

*2026-06-12*

Bonjour, je viens de découvrir l’application Aikui sudoku pour les couleurs il est impossible de placer les couleurs avec VoiceOver on entend pas le nom des formes de la grille à l’écran donc que ce serait possible de corriger ce problème dès la prochaine mise à jour de cette application. Merci. Nathalie

**Developer response:** Bonjour Nathalie,

Merci beaucoup d'avoir pris le temps de nous écrire. L'accessibilité est au cœur d'Aikui, et nous sommes vraiment désolés que le jeu soit aussi difficile à utiliser avec VoiceOver.

Vous avez raison : placer les couleurs et entendre le contenu de la grille, y compris les formes, doit fonctionner sans effort. Nous avons bien noté le problème et nous travaillons déjà à le corriger dans une prochaine mise à jour.

Merci de nous aider à rendre Aikui meilleur pour tout le monde.

Bien à vous,
L'équipe Aikui
