Mega Diamond Box is a casual puzzle game where you are given a grid of stars and you need to connect them without crossing the lines or touching the other positions.
To do this, you will be given a certain amount of moves, and depending on the level you are playing on, the number of moves will be different. Every time you use a move, you will lose one star.
The gameplay mechanics are simple and the goal is to connect the stars in a grid without crossing the lines or touching other positions.
The more stars you have when you finish the level, the higher the score you will get.
