This is a solitaire game where you score points by removing groups of connected pieces. A new game starts with the board filled with pieces of multiple colors. When 2 or more pieces of the same color are horizontally or vertically adjacent, they form a group. You can remove groups by clicking on any of their pieces; the remaining pieces will fall down to fill the gaps. When you remove a group, you score a number of points equal to the square of the size of the group minus 1. For example, removing a group of 5 pieces scores 4*4=16 points. To get a high score, you'll need to create groups that are as large as possible. The game is over when you've removed all the pieces, or when there are no groups remaining.


Clicking the highlighted cell will remove the group of 7 red pieces, scoring 36 points, and will cause a green piece to fall and join the large green group at the bottom.
