Sudoku Flags - Learn World Flags While You Play
Sudoku Flags
Sudoku Flags is a real, solvable 9x9 Sudoku puzzle with a twist: instead of digits, each number from 1 to 9 is represented by the flag of a different country, chosen at random for every new game. Play it exactly like a normal Sudoku - fill in the blank cells so every row, column, and 3x3 box contains each flag exactly once - or press the view-toggle button to animate every flag flipping over to reveal its number underneath, useful whenever you want the classic number view instead. Correct moves earn points based on your difficulty, your current streak, and how quickly you're playing, building up toward an all-time high score that's saved on this device.
- Flags replace numbers 1-9: a fresh set of 9 random country flags is assigned to the digits at the start of every game, so you see different flags each time you play.
- Flip to the number view any time: the view-toggle button animates every flag on the board and number pad over to its underlying digit, and back again - solving works identically in either view.
- Scoring rewards accuracy and speed: each correct entry earns points multiplied by your current streak, how quickly you're playing, and the puzzle's difficulty; completing a row, column, or box in the same move adds a bonus, while a wrong entry or a hint costs points.
- Your all-time score is saved on this device: every game's points add to a running total shown at the top of the board, so you can track your progress across sessions.
How do I know which flag is which number?
Press the view-toggle button at any time to flip every flag on the board and number pad over to its number - flip back to flags whenever you want to keep practicing.
How is my score calculated?
Each correct entry is worth a base amount multiplied by your current correct-answer streak, a speed bonus that's highest early in the game, and your chosen difficulty. Completing a row, column, or box adds an extra bonus, while a wrong entry, or using a hint, subtracts points and resets your streak.
Does my all-time score reset if I close the page?
No - it's saved in your browser on this device, so it carries over between games and visits. It won't transfer to a different browser or device, though.
