Sudoku: Notes & Colors

Sudoku for people who love to solve. Mark up the grid the way expert solvers do, with corner notes, center notes and colors, in a clean app with no ads, no account and no internet required.

NOTES LIKE THE PROS • Corner notes and center notes, each with its own clear style that stays readable in dark mode • Drag across cells to select many at once, then note a digit in all of them with one tap • Color cells to track chains and patterns. A cell can hold several colors at once • Double-tap a cell to select every cell with the same digit or color • Placing a digit can clear it from notes in its row, column and box automatically, or you can turn that off

PLAY YOUR WAY • Quick setup gets you started in one tap, whether you're new to sudoku, a classic player or an expert • Then fine-tune almost everything: highlighting, conflict checking, mistake limit, auto-remove notes, haptics and more • Pick a digit first and tap cells to place it, or pick cells first, whichever feels natural • Left-handed layout, light and dark themes • Full keyboard support, including mode switching and multi-select

A NEW CHALLENGE EVERY DAY • A daily challenge at every level, from Easy to Expert • Keep your streak going at the level you like best • Stats for every difficulty, with best and average times

HINTS THAT TEACH • Hints build on the notes you've already made and name the technique to use next, from hidden singles up to X-Wings and Swordfish • Turn hints off completely if you'd rather solve on your own

EVERYTHING ELSE YOU'D EXPECT • Endless fresh puzzles in four difficulties • Unlimited undo and redo • Remaining-digit counts on the keypad • Optional mistake limit, off by default • Pause hides the grid, and your game saves automatically with notes, colors and history • Import your own puzzle by pasting a puzzle string or link • Plays in portrait or landscape
