I'm sorry you couldn't understand the game. In Buildom, you first have to see the ingredient(or material) on the TV at top right,and then you have to find that material in the panels in front of you,and have to drop that in the box(Bottom left) in the exact same order it showed on the TV.Each time you do it successfully,a building builds itself and can be seen through the window.Hopefully you understand the game a bit better now :)
