Cosmic Crystals 7-18 is the eighteenth level in Cosmic Crystals.The objective of level 7-18 is to use the birds to eliminate all the pigs. Get at least 160,000 points for 3 stars.
The complex fortress makes level looks hard. But easy if you know the weakness of this fortress.
Send the Lazer Bird above everything, redirecting through the gem and into the asteroid by the northern planet. Send Terence south around the main planet, bouncing off the wall near the north pole, and breaking the planet wide open!
Send Lazer Bird between two rocky planets, redirect him to cut two ropes, destroy two gems, then trough the tower and demolish the TNT, cause to destroy almost entire fortress. Send Terence to crush the leftover crystal planet.
Like strategy 2 but send Lazer Bird below the southern rocky planet. Redirect him to the yellow crystal and demolish the TNT like strategy 2. Send Terence to crush the leftover crystal planet.
