Shoot a ball into the funnel on the Ruler's cart
	Have the panel on your cart shot
	The Ruler's cannon is far more powerful

The final assult, at the castle gates.
The contestant sits in a buggy at the top of a track which runs parallel to the castle. Inside the buggy is a tennis ball cannon. In front of the castle, one of the Rulers is waiting inside their own buggy - which is fitted with a volleyball cannon.
On 'go', the contestant sets off down a slope and along the track. Their aim is to shoot a ball into the small funnel on the front of the Ruler's buggy. The Ruler's buggy remains stationary, but can swivel to shoot their cannonballs towards the contestant. They're aiming to break the large panel on the front of the contestant's cart.
If the contestant manages to get a ball into the Ruler's funnel, sparks fly and they have stormed the castle and leave victorious!
However, if they fail to get a ball into the funnel before they reach the end of the track, or the panel on the front of their cart is shot by the Ruler during the shootout, they're defeated and the battle is lost.
Super version
The Ruler's cart also moves along a track, making getting a ball into the target funnel even harder.
