At the set time, the puzzle game starts up with an alarm sound. Since the alarm doesn't stop until the puzzle is solved, this is a powerful alarm clock that wakes even those who are not good at waking up. Another feature of this app is that it shifts to the alarm ready state just before the set time and always starts up at the set time. There are several puzzles to choose from, and you can increase the difficulty level by selecting puzzles at random.
