Hoot Grid is a calm logic puzzle about placing owls on a colorful grid. THE RULES ARE SIMPLE Place one owl in every row, every column, and every colored region. Owls cannot touch each other, not even at the corners. One clear goal, endless clean deductions. HOW YOU PLAY • Tap to mark a cell that cannot hold an owl. • Tap again to clear an X. • Hold to place an owl when you are sure. Every puzzle has exactly one solution, and the board stays clear and readable so the puzzle is always the focus. SMART HINTS THAT TEACH Stuck? A hint shows one helpful next move and briefly explains why. Follow the highlighted cells to place an owl or mark Xs yourself, so the puzzle still feels like your solve. A GENTLE CHALLENGE Work through 190 puzzles across multiple board sizes. Each level starts with three lives, a live score rewards clean solving, and your progress is saved on your device so you can pick up right where you left off. READABLE BY DESIGN Turn on high contrast for stronger region borders. Clear shapes, strong boundaries, and sound controls keep the board readable without relying on color alone. NO FUSS No account is needed to start solving. No ads. No purchases. Just you, the grid, and the owls. Find the perfect perch.
