The objective of Detonate 2 is to detonate the bombs before they reach the city below.
Move Bomb: Click and drag a bomb to move it.
Drag one black bomb into another to detonate them both. Click a white bomb to detonate it. Drag a red bomb into the thing throwing the bombs to hurt it. Click any powerups you see, because they're very helpful. The cheap way to do well in this game is to keep clicking the enemy so that the bombs will immediately detonate. However, if you want to feel like you've actually accomplished something, do it the right way.
