Place the pieces in such a way that you can make a complete horizontal line of blocks and make it disappear to lower the whole structure. If the structure reaches the top you will lose and you will have to repeat the whole thing from_ the beginning.
Maybe you think itīs a Tetris like any other that exists. Itīs nothing like the classic Tetris game, since in this one the fish are destroyed when they touch a surface.
What you will have to do is to get the big ones of a single color to reach one side or the other of the square, so that it is always touching. If you manage to do this, it will disappear, and the more grains of this color you make disappear, the more points you will get.
If you manage to chain a sequence of complete colors in only 1 shot, you will get these points multiplied by a larger number each time.
Will you achieve a record that no one else can beat?
