Block Puzzle is a famous logic game.
The rules is very simple:
A random sequence of shapes fall down the playing field. The objective of the game is to manipulate these shapes, by moving each one sideways (if the player feels the need) and rotating it by 90 degree units, with the aim of creating a horizontal line without gaps.
When such a line is created, it gets cleared and any block above the deleted line will fall. When 100 number of lines are cleared, the game enters a new level.
As the game progresses, each level causes the shapes to fall faster, and the game ends when the stack of shapes reaches the top of the playing field and no new shape are able to enter.
