Phineas and Ferb have started an incredible new project and they are waiting for you to help them do it perfectly! The brothers are constantly brainstorming original ideas, but this one is quite different from the ones you are used to! By playing S`No Problem game with Phineas and Ferb, you will help them build an enormous snow mountain where they can go snowboarding together! The brothers want to use a combo snow maker and an automatic tennis ball server to make their idea come to life. Help them build this huge mountain with Agent P`s help by bouncing the snowballs off a trampoline that they are holding across the yard and reach the goal which is shown on the screen in order to move on to the next level. If you do not manage to reach the goal which is set, the game will be over. However, if you are doing an amazing job, you should definitely attempt to reach the bonus height and obtain a higher score! You should use your mouse to move Phineas and Ferb left and right. Pay attention to the giant ice cubes and the puddles which are formed from missed snowballs since they can make things harder for you and get you further away from your goal. Also, keep an eye on Candace because you do not want her to get too nosy and tell her mum what Phineas and Ferb are up to and distract Agent P in the process. Make sure you have enough fuel to complete your mission because once you run out of it, the time will be up and the game will be over. Agent P will be there to help you fight off the evil Dr. Doofenshmirtz who is flying around in his hot blimp so as to melt away the brothers` mountain. Simply click your left mouse button in order to help Agent P fire a shot and push Dr. Doofenshmirtz`s blimp away from the snow mountain.
