This is a block-placing match-three puzzle with a twist on color mixing. ========================== HOW TO PLAY: Place blocks on board, Try to match 3 blocks of same color in a row. The goal is to survive as long as possible. ========================== RULES: You can put blocks onto existing blocks, and their color will mix up!(If the colors are different) For example, Cyan+Yellow = Red And Red+Blue = Black But note that BLACK blocks are dead, as they won't match with other blocks. If the blocks are the same color, color will not change but instead, there will be DOTs appears on the block, and when it reaches 4 the tile would explode. Gradually, the board will randomly grow. If you match 4 or 5 blocks in one time, you get a RAINBOW block; 6 blocks or more. you get a PLUS block to grow the board anywhere you want.
