Your goal is to knock the building down with your limited supply of TNT. In order to beat the level, you need to get all the metal beams below the green line.

Click and drag the dynamite bundles onto the building's metal beams to place them. Once you've planted all your dynamite, click the detonator to set them off. You can only plant one dynamite per metal beam.

Get the building as low as possible to get the best score... lower is better!
