Describe it
Tagline
Where color meets calm.
One line
A calm, colorblind-friendly color sudoku, nine colors instead of numbers, on a board everyone can read.
Short
Aikui is a color sudoku for iPhone and iPad that swaps numbers for nine colors chosen to stay distinct for the common kinds of color blindness. A free Pattern Mode adds a unique shape to every color, so the board is readable even when color alone is hard. No ads, no subscription, ever.
Long
Aikui rebuilds sudoku around color you can actually tell apart. Instead of numbers, you solve with nine hues drawn from the Okabe-Ito scientific palette, chosen to stay distinct under the common forms of color blindness. Turn on Pattern Mode, free for everyone, and each color also carries its own shape. There is no timer and no pressure: just a quiet board, gentle haptics, and a light or dark appearance that follows your device. A bundled bank of 10,000 hand-checked puzzles plays fully offline, across four difficulties, with cell-first or color-first input, pencil marks, and undo. A shared Daily Puzzle and Game Center leaderboards reward depth, never speed. One optional purchase unlocks everything, owned forever, with no ads and no subscription.
