App Description

Zero is a very special number. It is not a positive number nor a negative number. In fact, the evolvement of zero is much later than others. In this app, we would like to introduce another function of zero. Hope that all of you can discover that yourself during playing this game.

Very simple to play:
1. Number blocks (can be positive or negative) are falling down on the screen.
2. The player needs to stack number blocks on the columns.
3. To clear a column, make the sum of the numbers on the column equal to 0.
