Sudoku Ultra +

Meet an endless Sudoku challenge powered by an embedded AI puzzle engine—fresh boards, progressive difficulty, smart assistance, and a beautifully focused way to play.

Sudoku Ultra gives you an endless stream of fresh puzzles, powered by an embedded AI puzzle engine built for focused play.

Every board is generated on your device. Complete a level and the next challenge is ready, with progressive difficulty that builds through your journey while preserving the pure logic that makes Sudoku so satisfying.

Play your way with thoughtful tools designed to keep you in the flow: • Pencil Mode for candidate notes • Smart conflict detection and instant mistake checks • Highlights for matching numbers and related areas • Optional timer, error limit, and number-first input • Helpful hints when you need a nudge • Automatic note cleanup and used-number controls • Haptic feedback and clear cell-by-cell accessibility labels

Make every session your own with 35 carefully designed themes and support for 20 languages. Track your best time, average time, win streak, flawless solves, total victories, and long-term milestones as you improve.

Volchron Vision Mode adds a dedicated high-contrast theme and tactile number feedback to support players with color-vision differences and anyone who prefers stronger visual separation.

Start a quick puzzle, settle in for a longer run, or return to your saved game whenever you are ready. Sudoku Ultra keeps the interface quiet, the controls responsive, and the next challenge waiting.
