At first you have to solve a puzzle and achieve the target score within the time limit to go to next level of location. Swap them in such a way that you align three or more similar pictures along vertical or horizontal direction. The consecutive similar pictures vanishes and adds up your score. Once you enter the next location, watch that location keenly for the given time and spot out the changes that are been done in that location. Three clicks on wrong items will lead to game over. Go through all the 3 levels.
