About this app
Inequality Sudoku is a fully offline number logic game. Fill each row and column with non-repeating numbers while also satisfying the greater-than and less-than signs between neighboring cells. Compared with classic Sudoku, it puts more focus on reading inequality chains, eliminating candidates, and making local deductions, making it ideal for short logic-training sessions. Features include offline puzzles in multiple grid sizes, candidate notes, conflict checking, hints and answer validation, timer statistics, and local progress saving. All puzzles and records stay on your device. No login, no internet connection, and no personal data collection are required.
