RAIBLO

Destroy the falling blocks (red, green, blue, yellow, cyan, purple, white) by the RGB bullet.
Any of the blocks in the top row will come down.
In addition, by hitting the block of the top row in the bullet directly, you can also drop the block.

You can destroy the falling blocks if bullet and block is same color.

But yellow, cyan, purple and white is composite color of red and green and blue.
These color blocks can be destroyed by each of the bullet as follows.

yellow = red + green
cyan = green + blue
purple = red + blue
white = red + green + blue

For example, when red bullet hit yellow block, yellow block will be green.

Piled blocks can be destroyed if three or more same color blocks are connected up and down, left and right.
Piled blocks are higher score than falling blocks.
