Runelocked Chest

OK, if you've never played candy crunch or any knockoffs of this, like me you'll be rather puzzled and frustrated about the lack of information on how to solve these. Here's the routine:
1) you move a piece by clicking on the piece you want to move, then clicking on the piece that is occupying the space where you want to move the first piece you clicked on.
2) You can only move one space, either up, down, left or right. You cannot move diagonally.
3) You can move a piece ONLY if you move it to a slot that creates a line of 3 or more of the same design/color, without spaces. That's it! No other move allowed.
4) When you create a line, either horizontal or vertical, not diagonal, those pieces in that line disappear and pieces move from above to fill the vacated spaces. If the pieces that disappear are the color you are trying to destroy, then they add to your total of destroyed pieces. If they are not the required color, then hopefully the movement of pieces offers other chances to destroy the right color.
5) I've found that it's not worth doing too much strategizing; there usually just isn't opportunity for it. Do keep an eye out for possible lines of the required color, but If you just make lines of 3 or more of any color to move the pieces around enough, eventually you will destroy enough of the right color to complete the puzzle.
