This is a hard stage to obtain the three stars mastery. You will have to deal enough damage to all the blocks while killing all of the pigs in just two shots.
Launch your first shot towards the ice block. You want to break the ice holding block so that the whole thing would crumble down.
Power Activation Point
Activate the split power shortly before you hit the blocks. The strikes should be concentrated so that they break through the ice and wooden blocks instantly when they do hit.
First Shot Result
The whole “cave” crumbles down, leaving you with the open shot to kill the final pig.
Launch your second shot at the location shown in the picture. This is the weakest point for your laser gun to get to the final pig.
Second Power Activation Point
Tap and shoot out your lasers to penetrate the blocks and put an end to the pig.
Second Shot Result
You will earn your three star mastery if you have destroyed enough blocks. Note that this stage is really hard and rely on much of your luck. Keep on trying if you do not have enough score.
