-
Every day, the order of the tetrominos and colors is shuffled, and a randomly sized game board is generated.
-
Each tetromino you place has a special block that can earn you points:
-

Wants blocks above it, and to be near blue blocks.
1 point for every filled cell above this, and additional increasing points for every blue block around this.
-

Wants to be high up, with nothing above it.
1 point for every cell (filled or empty) below this. Minus 1 point for every filled cell above this.
-

Wants to be near special blocks.
5 points for every other special block around this.
-

Wants space to breathe.
Increasing points for every empty cell around this. Cells outside of the grid are not considered empty.
-
The game ends either when you run out of blocks to place, or when a placed block sits outside of the grid.
