riverdrift says Attain the highest possible score by removing as many rows as possible.
Match three in a row horizontally, vertically or diagonally,
The line will be removed and more pieces added.
If the added pieces form a line as well, it is removed too, and it is also added to your score.
You can match a line by swapping two pieces that are horizontally or vertically next to each other.
First click on the one first of the pieces that you want to swap and then on the second.
The game is over when you can not form a new line by swapping two pieces.
The game will let you know when it is over. If you think it is over and can't find a move keep looking. OK
