Flagdoku
Fill a 3x3 grid with flags that match both their row and their column.
Every day: A new numbered 3x3 grid every day, the same for everyone, with flag features on the rows and columns; name a flag that fits both for each of the nine cells, and find the flag of the day that fits every category. New puzzle: Midnight Eastern Time (America/Toronto), per the game's date service.
Flagdoku is a daily grid game about flags. Each row and column names a feature, such as three bands, vertical stripes, a colour or a region, and every cell wants a country whose flag fits both. Each correct cell scores a point, nine at most, and rarer answers stand out in the results.
About Flagdoku
Flagdoku is a flag puzzle in the style of the sports grid games. Every day a new numbered grid appears with three criteria across the top and three down the side. They describe flags rather than countries: colours such as blue, white or red, layouts such as three bands or vertical bands, symbols such as a cross, and sometimes a region such as Europe. A cell is filled by naming a country or territory whose flag meets both its row and its column.
Each right answer is worth a point, so a full grid scores nine, and wrong answers score nothing. Answers are marked as unique, rare or frequent depending on how many other players chose them, which rewards less obvious flags. There is also a flag of the day, one flag that fits every category in the grid, to find as a bonus. Clicking a category shows exactly what it means, which helps with edge cases such as capital city flags or hyphenated names.
Past grids are open by clicking the number cell, and the site has a flag search, achievements, a random mode, a custom mode and a flag connections game. The same maker runs Futdoku, a football version, and Wildlife Sudoku.
It suits players who like Immaculate Grid style puzzles and know their flags, or want to learn them by looking closely.
How to play Flagdoku
- Read the three column criteria across the top and the three row criteria down the side.
- Pick a cell and name a country whose flag fits both its row and its column.
- A correct flag fills the cell and scores a point; a wrong one scores nothing.
- Fill all nine cells for a score of up to nine.
- Look for the flag of the day, which fits every category in the grid, then share your result.
Tips
- Click a category to read its exact rule before answering; some exclude cases you might expect.
- Start with the cells where the two criteria overlap least; they have the fewest possible flags.
- Save well-known flags for the easy cells and reach for small territories elsewhere to score rare answers.
- Use the flag search to learn flags between days; it is the fastest way to improve.
