SudoLuma: Sudoku Puzzles

Learn sudoku as you play. When you get stuck, SudoLuma doesn't just hand you a number. It shows you where to look, names the technique and walks you to the answer, one step at a time. Play with one hand, learn 24 real solving techniques and keep your daily streak alive.

HINTS THAT TEACH • Every hint has four steps you open one at a time: where to look, which technique applies, the marked cells, then the answer. • Hints start from your current board, so they always point to your next logical step. • If there's a mistake on the board, the hint tells you first and marks the cells. • Tap Stuck to check your notes for missing or already eliminated candidates.

PLAY WITH ONE HAND • One-handed mode for your left or right hand puts the controls on your thumb's side. • A D-pad lets you move around the grid without stretching. • Easier reach slides the grid down so the top rows come to you. • Available on iPhone models with a taller screen.

LEARN REAL TECHNIQUES • 24 lessons, from Hidden Single to X-Wing, Swordfish, XY-Chain and Nishio. • Each lesson explains what to look for, why it works and how to apply it, with an example board taken from a real puzzle. • 118 practice positions. Three correct answers and you've mastered the technique.

DAILY PUZZLE, STREAKS AND BADGES • A daily puzzle arrives every midnight, the same for everyone that day. • Solve it to grow your streak. Missed a day? A streak break keeps it alive, once a month. • 12 badges to earn, from your first win to a one-year streak.

FIVE LEVELS, YOUR RULES • 2,400 built-in puzzles across Easy, Medium, Hard, Expert and Master. • Three mistake modes: Relaxed, Classic or Challenge. • Notes clear themselves as you place digits. • Cell first or digit first input, undo and redo, and an optional timer. • The same digit and its row, column and box are highlighted. • Your game saves automatically, so you can pick up right where you left off.
