About Flagdoku
Flagdoku is a free daily flag puzzle that combines vexillology with a sudoku-style grid. The board has nine cells in three rows and three columns, and every row and every column carries a category clue. Each cell must be filled with a flag that satisfies the row clue and the column clue at the same time, so a country that fits one line often fails the other. Players type flag names into the cells, and the grid scores each answer on the spot.
