Killer Sudoku Sunrise

Killer Sudoku Sunrise is sudoku with sums. Dashed cages cover the grid, each with a small total in its corner, and the numbers inside a cage must add up to that total without repeating. From Medium up the board starts empty, so the sums are your only clues.

CAGES AND SUMS
• Each cage shows its total in the top corner, in a warm amber that stays easy to read
• Under the board, the selected square's cage and its running total: "This cage: 14, 9 so far."
• The cage sums card lists every set of numbers that can make each total, for cages of two to nine squares, and marks the totals with only one possible set
• Optional checks tell you when a cage goes over its total or repeats a number

FIVE NEW PUZZLES EACH MORNING
• One puzzle at each level from Gentle up to Expert, and every player gets the same set that day
• Gentle starts with a few numbers in place and cages that can only be filled one way, a friendly first step for beginners
• Play extra puzzles at any level, any time, from thousands made by our own generator
• Missed a morning? The calendar keeps every earlier day's five

HINTS THAT SHOW THE MATH
• Ask for a hint and it comes in steps: where to look, what follows, and the reasoning behind it
• "Only 8 and 9 make 17, so these two squares hold 8 and 9." "Row 3 adds up to 45. The cages wholly inside it make 38, so the one square left over, row 3, column 5, must be 7."
• Learn has a hands-on lesson for each technique, on a real board, from one-way cages through innies, outies and wings
• Each puzzle has a single answer that logic alone can reach, with no guessing

YOUR GAME, YOUR PACE
• Pencil marks, undo and redo
• Pick how much checking you want: none, clashing numbers, or wrong numbers. You can always keep going after a slip
• Choose the number first or the square first
• The clock stays hidden until you switch it on; after that, the Stats screen tracks your best time and your average

SUNRISES IN A ROW
• A run of days played and your best run. Miss a day and a new run quietly begins. An optional reminder comes at the hour you pick

COMFORTABLE TO READ
The digits are set in Atkinson Hyperlegible, a typeface made for easy reading, and the cage sums and the app's words grow with your text size. TalkBack reads each square with its cage and total, highlights differ in shape as well as color, and the light and dark looks follow your device. Laid out for phones and tablets.

ONE BANNER, NEVER ON THE BOARD
A single banner sits on Home and on the finish screen, and nowhere while you solve. Ads there are limited to general-audience content and are never targeted using your activity. A one-time Remove ads purchase takes the banner away for good. There is no account to make.
