In this video, I've tried to show you the level 1 and 2 .
Level 1 is the easier one.
Level 2 is the immediate level.
Level 3 has two ways to play, which is quite difficult to the novice
In fact, there is level 4, where I 've upgraded the original Submarine string puzzle, the video of which will follow.
