The object is to line up three or four icons that are the same in the win row (middle row). Depending on what you line up you win a certain amount of Neopoints or prizes. As you play every once and a while you are allowed to check boxes and hold some icons to have a better chance of winning the next round. You can also win when the numbers all light up on the bottom and the volacano erupts as shown in the screenshots below. The numbers light up as you get icons that have little numbers in the corners. They are added together and light up the corresponding numbers on the bottom of the game. These numbers are sometimes rolled over to the next turn and sometimes not.
