Getting Experts on Lego Fever

I have a computer game called Lego Fever. There are three different modes: clump, chase, and puzzle. The chase is when you get grey people and you use lego bricks to guide Harry and Jens. Harry and Jens are the lego brothers, who are trying to put color in a gray world. The clump doesn't have Harry and Jens. You have to move bricks onto other bricks to make stacks of three. The stacks then disappear. You win when you have made a certain amount of bricks disappear. The puzzle mode is kind of like the chase mode only different. In the puzzle mode you stay where you are and guide Harry and Jens using lego bricks. There are grey people that you free.
