## What is Kaidoku · Daily Sudoku?

Play Sudoku without ads, at home or on the go. Choose a difficulty, take on the Daily Challenge, or try Cipher Mode: the numbers are replaced by symbols whose meanings you uncover as you solve.

A NEW CHALLENGE EVERY DAY
Everyone gets the same daily puzzle. Build your streak and compare your time on the Game Center leaderboard.

PLAY AT YOUR LEVEL
Start with Easy. Premium unlocks Medium, Hard, Expert and Master. Each difficulty has its own mistake limit.

HELP WHEN YOU NEED IT
Keep track of possibilities with pencil marks, undo an entry or use a hint when you get stuck. Adjust number highlighting, sounds, haptics and number size to suit you.

PICK UP WHERE YOU LEFT OFF
Your current game is saved automatically. Follow your best times, completed puzzles and streaks in Statistics, and keep the Daily Challenge on your Home Screen with a widget.

TRY CIPHER MODE
Solve Sudoku with letters instead of digits. Premium adds Greek letters, runes, zodiac signs, shapes and planetary symbols.

START FOR FREE
Each day you can start one free Easy game, in classic Sudoku or letter-based Cipher Mode, plus the Daily Challenge. Both modes share the one-game allowance. Continuing an unfinished game does not use another allowance. Three hints per game and light and dark appearances are included. Premium unlocks unlimited games at all five difficulties, unlimited hints, four additional themes and five additional symbol sets.

Play offline on iPhone and iPad. No ads and no Kaidoku account required. Available in 19 languages.

Premium is a one-time purchase with no subscription.
