you should change the positions of different blocks to make them in the horizontal or vertical line to get points. At the beginning of the game, you will see three piled images falling down slowly. The blocks are in different color, such as green, purple, white, red and blue. If you can make the blocks of the same color in the same level, the images will disappear and you will win points. You will gain 200 points every time you succeed to arrange them properly. You press use up arrow key to change the positions of blocks to fulfill your plan. You can also press down button to descend the blocks quickly. You will go to the next level if your score reached enough points. Take a try and have fun.
