Classic Puzzle Brick

Classic Puzzle Brick is game pieces shaped composed of four square blocks each.

Classic Puzzle Brick is similar to "Xep Hinh" or "Xep Gach" in Vietnam.

A random sequence of pieces fall down the playing field (a rectangular vertical shaft, called the "well" or "matrix"). The objective of the game is to manipulate these pieces, 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 of ten units without gaps.

When such a line is created, it disappears, and any block above the deleted line will fall. When a certain number of lines are cleared, the game enters a new level.

As the game progresses, each level causes the pieces to fall faster, and the game ends when the stack of pieces reaches the top of the playing field and no new pieces are able to enter.

[How to get score]

All of the pieces are capable of single (1 point) and double clears (3 points).

I, J, and L are able to clear triples (8 points).

Only the I pieces has the capacity to clear four lines simultaneously (15 points).
