There will be blocks of several colors. You have to click any block then after that make a rectangle with four corners. The four corners should have the same color. While playing, sometimes you will see a bomb and it has to be cleared otherwise it may explode the area!! Take time bonus to increase your time limit. If you cross the time limit you have to start the game so make rectangles of same color as fast as you can. The wider rectangle you can make the more score you will get. There are several levels. The advanced levels are harder!! Have fun!!
