Hue9

Few puzzles fit into a day as easily as Sudoku: a few spare minutes on a train, a grid in the corner of a newspaper, a pencil and nothing else. Its numbers have always been only labels, though, and nine colours can do the same job, as long as everyone is able to tell them apart.

Hue9, developed by David, turns classic 9×9 Sudoku into a puzzle played with nine colours instead of numbers, and is designed so that color is never the only way to differentiate it. Symbol Mode pairs every hue with its own shape and switches on automatically when related accessibility features are enabled. It is not just that because VoiceOver describes each cell with its row, column, value so the same puzzle can be solved by anyone, in whichever way suits them.
