About Coindoku

Coindoku is a brain puzzle game that merges Sudoku with Minesweeper — place coins correctly across the board and see how many you are able to collect.

How to Play Coindoku

Toggle between Marks and Coins modes to work through the board. Coin placement follows three rules:

• Only one coin per color.
• Coins cannot be neighbors with other coins.
• No row or column occupied by a coin may contain another coin.
