The game presents a series of physics-based puzzles, the objective being either to keep structures made of blocks from being knocked down or to knock them over by various means, using the Wii Remote to throw, shoot, and grab at the blocks. "Boom Blox" features a realistic physics system; the angle at which a projectile is launched and how fast it is thrown as well as the mass of the projectile and the type of blocks it comes into contact with influence the results of an action.
