LionDoku is a relaxing logic puzzle game that challenges you to observe, reason, and find the correct solution. In LionDoku, each lion must stand alone. Every row, column, and colored region must contain exactly one lion. No two lions can be placed next to each other, even diagonally. Every puzzle has its own hidden logic. Study the board, rule out impossible positions, and follow the clues to place every lion correctly. Easy to learn and satisfying to solve, LionDoku is designed to exercise your mind at your own pace. You can also enjoy Nonogram picture puzzles. Use the number clues beside each row and column to determine which cells to fill. Mark empty cells with Xs, reveal the hidden pixel picture, and complete hundreds of increasingly challenging levels. Features: • More than 8,000 logic puzzle levels • 500 Nonogram picture puzzle levels • Daily puzzle challenges • Helpful hints when you get stuck • Simple, colorful, and intuitive design • Tap or swipe to fill Nonogram cells • Multiple language support • iCloud progress synchronization • Light and dark mode support Whether you want a quick break, a relaxing picture puzzle, or a challenging brain workout, LionDoku always has another puzzle waiting for you.
