## What is Boom! Circus Knockdown?

Roll up, roll up! Aim the circus cannon, fire, and knock every prop off the table before you run out of cannonballs.

Every shot has the same strength, so it all comes down to where you aim. Hit the base, let gravity help, and watch the tower come down to the cheers of the crowd.

THE SHOW
• 48 handcrafted stages across three acts: Opening Act, Balancing Acts and Grand Spectacle
• Endless encores after Act 3: new sixteen-stage acts with ten illustrated themes
• New tricks in every act: pendulums, spinners, rising bars, wrecking balls, fire hoops, bomb balloons, falling curtains, spotlights, blackouts, folding shutters, ring posts and a closing press
• A live crowd that gasps, cheers and groans with every shot
• Real 3D physics: every block tumbles, slides and bounces its own way

SIMPLE TO PLAY
• Press, aim and release, or just tap where the shot should land
