Dotdoku

Put your logic skills to the test with Dotdoku. A red-and-blue puzzle game built around clever deduction.

Fill every spot on the grid while following three simple rules:

• Keep an equal number of red and blue spots in every row and column
• Make sure adjacent lines are different
• Use numbered spots to determine how many surrounding spots share their color

It’s easy to learn, but every new grid brings a satisfying challenge. Begin with a guided, learn-by-playing introduction, then progress through increasingly difficult puzzles that combine color balance, unique lines, and numbered clues.

STAY SHARP

Each level gives you three lives. Think carefully, avoid mistakes, and complete the grid before your lives run out. If you get stuck, use a Hint to reveal a useful spot or try a Smart Hint for extra guidance.
