Our promise. The things that make Aikui playable for people with color vision differences are free for everyone, forever. The colorblind-safe palette and Pattern Mode are never behind the paywall, because accessibility is the point of the game, not an upsell.
A colorblind-safe palette by default
Most color sudoku games pick colors that look nice but blur together for the roughly one in twelve men and one in two hundred women with color vision deficiency. Aikui starts from a different place. The default palette is built from nine hues chosen to stay distinct under the common kinds of color blindness, the same family of colors trusted in scientific figures where being able to tell categories apart actually matters.
We hold the darkest color to a measured contrast floor so it never collapses into its neighbor under red-green color blindness, and we check every palette color against simulations of deuteranopia, protanopia, and tritanopia before it ships.
Pattern Mode, for when color is not enough
Some people cannot reliably tell any color scheme apart. For them, and for anyone who simply prefers it, Pattern Mode overlays a unique shape on each color: a circle, a triangle, a square, a diamond, a star, and so on. With Pattern Mode on, the board is fully playable using shape alone. It is free, it works with every palette, and it pairs with the system Differentiate Without Color setting.
Works with the system you already use
- VoiceOver. Every cell, color, and control is labeled, so the board can be read and played by ear.
- Dynamic Type. Text respects your preferred reading size.
- Differentiate Without Color. Aikui responds to the system setting and can lean on shapes automatically.
- Reduce Motion. Calm animations become calmer still, with the gentle place-and-solve effects stepped back when you ask for less movement.
- Light and dark. Two hand-tuned color stacks, not one auto-dimmed the other, so the nine-by-nine structure reads clearly in either.
- Haptics you can turn off. A soft, consistent haptic family that you control.
Calm by design
No timer, no flashing rewards, no pressure. For players who find busy, loud games overwhelming, Aikui is deliberately quiet. It is a place to think, at whatever pace suits you.
Spoken in your language
Aikui is localized into 50 languages, with an in-app language picker so you can choose the one that reads best for you, independent of your device language.
