Every puzzle has a unique solution that can be found using logic alone—no guessing required. Plan carefully, connect every island correctly, and solve increasingly challenging puzzles. Features - Many unique logic puzzles - Multiple difficulty levels - Simple and intuitive controls - Train your logic and concentration - Relaxing gameplay with no time limits - Suitable for beginners and experienced players - Hours of brain-teasing entertainment Can you solve every bridge puzzle? Good luck!
