## Description

Classic Sudoku and Killer Sudoku in one app. Six real difficulty levels, a daily challenge, twelve themes — and every board is built offline on your phone.

Two puzzle games in one app: classic Sudoku and Killer Sudoku. Every board is built on your phone, so nothing needs a connection — play on a plane, on the metro, anywhere.

CLASSIC SUDOKU
The 9×9 grid you know. Fill every row, column and 3×3 box with the digits 1 to 9, exactly once each.

KILLER SUDOKU
Dashed cages tell you what a group of cells adds up to, and you work the rest out from the sums. Easy and Medium hand you a few digits to start from; from Hard up, the cages are all you get. A different game, not a skin.

SIX LEVELS THAT ACTUALLY MEAN SOMETHING
Easy, Medium, Hard, Expert, Master and Extreme. A level is set by the hardest technique the board needs — not by how many digits are missing. Win at one level to open the next, and each mode keeps its own ladder.

A DAILY CHALLENGE
One puzzle a day, the same for everyone, alternating between the two modes. Nothing is downloaded: the date itself builds the board, so it works offline too.

HELP WHEN YOU WANT IT, NEVER WHEN YOU DON'T
• Notes for pencilling in candidates, cleared automatically as you place digits
• Hints, undo and an eraser
• Optional highlighting for duplicates, matching digits and the row, column and box you are in
• Mistake limit, timer and score — each one can be switched off

MAKE IT YOURS
Twelve colour themes in light and dark, plus Relaxing mode: nine calm night palettes with gentle motion and lullabies for late-night solving.

TRACK YOUR PROGRESS
Wins, win rate, best and average time, best score, current and longest streak, and flawless finishes — kept separately for every level and both modes.

Free to play with ads. One optional purchase, Premium, removes every ad and unlocks unlimited hints, second chances without ads and every theme and lullaby. It is a single payment — there is no subscription and nothing renews.

iPhone and iPad. No account, no sign-up, no internet needed.
