Sudoku BrainTrain delivers a premium Sudoku experience with a clean, distraction-free design. Whether you're picking up Sudoku for the first time or you're a seasoned solver, Sudoku BrainTrain has the right challenge for you.
Every puzzle is uniquely generated with a guaranteed single solution, so you'll never see the same board twice. Choose from four difficulty levels — Easy, Medium, Hard, and Expert — and work your way up as your skills improve.
SMART FEATURES THAT HELP YOU SOLVE
Pencil Marks — Toggle notes mode to jot down candidate numbers in any cell. Notes are displayed in an intuitive 3x3 mini-grid layout, and they're automatically cleared when you place a confirmed number in a related cell.
Intelligent Hints — Stuck on a tough cell? Use one of your three hints per game. Hints prioritize your currently selected cell, giving you exactly the help you need without solving the whole puzzle for you.
Conflict Detection — Mistakes are highlighted in real time. If a number conflicts with another in the same row, column, or 3x3 box, you'll see it immediately.
Undo Support — Made an error? Undo your moves one step at a time to get back on track.
PLAY ON YOUR SCHEDULE
Save & Resume — Pause any game and pick up right where you left off, even after closing the app. Your progress is automatically saved when you leave.
Unlimited Saved Games — Juggle as many puzzles as you like. Browse your saved games, see your progress at a glance, and resume or delete any game with a tap.
Completed Games History — Track every puzzle you've finished with a record of the difficulty and your completion time.
DESIGNED FOR FOCUS
Clean Interface — A minimal, modern design that puts the puzzle front and center. No ads, no clutter.
Dark Mode Support — Switch between Light, Dark, or System theme to match your preference and reduce eye strain during late-night solving sessions.
Timer — Track how long each puzzle takes and challenge yourself to beat your best times.
