The object of Smarts is to earn points by removing hearts from the game board. You remove hearts by clicking on a group of two or more hearts of the same color. You can earn big points for big groups of hearts, so think about how each move changes your groups. As you remove groups of hearts, the remaining hearts will slide down and to the right. Try to remove as many hearts from the board as possible. You will receive a bonus for leaving fewer than 20 hearts.
The game ends when there are no more groups of hearts to remove.
