## What is Killer Sudoku?

Killer Sudoku: Quick Notes gets you to the logic faster. Fill every valid candidate in one tap without revealing the solution, then solve calm, adaptive Killer Sudoku grids at your pace.

SOLVE AT YOUR PACE
Choose from four difficulty levels, from a gentle introduction to a true Expert challenge. Difficulty adapts as you complete puzzles.

ALL CANDIDATES IN ONE TAP
Automatically add every valid candidate as a note. The app never reveals the answer — it simply removes the routine setup so you can focus on logic.

QUICK INPUT
Select a digit first, then place it across the grid with fast, precise taps. Quick input and note mode can be used together.

EXPLORE DIFFERENT MOVES
Save the exact board state as a Branch, try an idea, and return to it whenever you want.

CHALLENGE FRIENDS
Share a spoiler-free code and let a friend solve the exact same difficulty, cages, and starting grid. No answers are included.

SHARE YOUR RESULT
Create a polished result card with your time, mistakes, hints, streak, and challenge code using the iOS system share sheet.

BUILT FOR FOCUS
A calm, modern interface, clear cage sums, candidate highlighting, undo and redo, hints, statistics, themes, and automatic progress saving.
