Play Instructions:

Move your cursor along the stack of gems. Click to swat two gems even if one of them is missing. You can swap gems only horizontally. You can swap gems even if they don't mach in color. Match three in a row or in column to remove them. Don't let your stack reach the top row or you will lose. When the top row has one or more gems you have only limited amount of time to move the gems and free the row. Often just removing one or two gems from the top will help but think fast and don't let them become too much.
