Waldoku vs Obrazko

Waldoku is a calm logic puzzle game about finding hidden dogs on a square board. Each level hides the same number of dogs as the board size. Use color areas, rows, columns, and adjacency rules to narrow down the correct tiles. The rules are simple: - Each color area has exactly one dog. - Each row has exactly one dog. - Each column has exactly one dog. - Dogs cannot touch each other. Mark tiles that cannot contain a dog with X, then double tap the tile where you think a dog is hidden. When many tiles can be ruled out at once, drag across the board to mark X quickly. The early levels introduce the rules step by step, then larger boards and combined clues add more depth. If you get stuck, hint and dog finder items can help you continue. Waldoku is designed for short puzzle sessions, careful thinking, and the satisfying moment of finding the exact answer.

Fill in the grid using the number clues next to each row and column — and watch a hidden picture slowly appear in front of you. Obrazko is a classic nonogram — also known as a griddler or a Japanese crossword — that rewards patient, logical thinking with a clear, satisfying payoff: uncovering exactly what's hiding in the grid. No guessing, no luck — every level has exactly one solution and can be solved with pure logic, one clue at a time.
