Falling 3D Blocks

这有点像俄罗斯方块，除与3个维度，而不是2

* Drag or swipe your finger on the screen to move the currently dropping figure.

* Tap the screen to rotate the currently dropping figure.

* Form a complete line of blocks in the y-direction to clear a plane (and score points). When the blocks reach to the top, the game ends.

It's sort of like Tetris, except with 3 dimensions instead of 2. It uses a set of 7 distinct figures that can rotate in different directions.

Whereas, with Tetris, you clear lines, in this game, you clear planes. And to clear a plane, you form a complete line of blocks in the y-direction. [Here, x-direction is from left to right and y-direction is from front to back (or back to front)].

Remember to use your finger to drag each figure to the desired location before you drop it onto the bottom grid plane.
