Tetris bricks are falling, the only way to interact with them is to shoot one or more blocks while they drop. You can move on all the already dropped bricks. Of course, the main goal is to make lines, like in real Tetris. You lose if columns are too high, like in real Tetris...

How to play

Well, it's quite easy :

If you have ever play a Tetris clone game, you know how to score : you gain points when a line is complete, the more lines made at the same time, the more points you get.

If you have ever play a shoot'em up game, you know the basis of the game play : just move and shoot. You can move on every brick of the board, you can shoot falling bricks. There are some bonuses that can be collected once down, some other that need to be shoot. There are also some malus, destroy them before they are down or deal with them :

2 of them let you increase (max 5) or decrease (min 1) your number of max shoot allowed,
the bomb will also destroy the 8 surrounding blocs when shoot (can be shot while falling, but also on grid)
the laser will destroy all blocs on same line when shoot, (can be shot while falling, but also on grid)
the monster bloc will create a monster when fall down : the monster will move randomly on grid. You can shoot it. You could also destroy monster bloc while falling
the line shield will disable the ability the remove a whole line when complete. If you didn't destroyed it while falling, the only way to remove it is to shoot a neighbour bomb, or a laser on the same line.
