Your goal is to free all the trapped Snoodsby launching other Snoods at them. If you connect three or more Snoods,they will transport away.
If that leaves any Snoods not connected to thetop of the playing field, they will fall to safety. Don't take too long,though: every Snood you launch increases the danger level. When thegauge fills up, the Snoods will shift downward.
