iPhone
Five levels, from a 26-cell Flash to Extreme. Every puzzle is rated by the techniques it needs and solves by logic alone. No ads. No account. Nothing leaves your phone.
Deep underground, in an ancient elder dungeon from a lost civilization, Captain Kaelen has kept watch over the mysterious encoded numbers for a hundred years. Can you solve the puzzle?
CLASSIC SUDOKU, NOTHING ADDED
Nine rows, nine columns, nine boxes. Each one holds 1 to 9 exactly once.
FIVE LEVELS
• Flash — an Easy puzzle with only 26 cells open. A game for a quick break.
• Easy, Medium, Hard, Extreme — each one a band of solving techniques.
NEVER A GUESS
Every puzzle is rated by a technique solver and has exactly one solution. You never need to guess. If you are stuck, there is a step of logic you have not found yet.
HINTS THAT TEACH
Stuck? A hint shows you where to look and why, then marks the cells. It gives you the answer only if you ask.
TOOLS THAT STAY OUT OF THE WAY
• Pencil marks that clear themselves when you ink that numeral in the same row, column or box.
• Undo, always free. Erase any numeral you placed.
• A wrong numeral flashes red and does not stay. The mistake counter keeps an honest score.
THE LEDGER
Solve a puzzle and Captain Kaelen reads the ledger: your time, mistakes and hints, your best time on that level, games solved, your run of perfect games, and your best run.
PICK UP WHERE YOU LEFT OFF
The game saves after every move. Close the app, come back tomorrow, and tap Continue. The clock stops while you are away.
HONEST BY DESIGN
• Free. No ads. No in-app purchases. No account.
• Works offline, anywhere.
• Collects no data at all. Your save stays on your phone.
