How the Daily Killer Sudoku Puzzle Works
Everyone gets the same Killer Sudoku cage puzzle for the same date and difficulty. The small number in each cage is the target sum, and numbers cannot repeat inside that cage.
Daily Killer Sudoku Difficulty
Easy uses smaller cage groups and more help. Medium is balanced. Hard and Expert use tougher cage patterns, fewer hints, and stricter mistake limits for stronger leaderboard runs.
Daily Killer Sudoku Leaderboard
Signed-in clears save to a separate Daily Killer Sudoku leaderboard, so regular Sudoku, Killer Sudoku, and daily challenge scores stay clean.
