INSTRUCTIONS: Click inside the 'aiming arc' to fire a piece of fruit.

Control the angle by clicking up or down, and control power by clicking closer or further away from the catapult. Some fruit weighs more than others, and you can see what's coming next inside the basket behind you.

Try and knock out as many marauders as you can - but if three get to your castle, then it's game over!

KEYBOARD: Use the up and down arrows to control the angle of the shot, and left and right to control power. Press space to fire.

ABOUT

Help Sir L. Norton defend his castles from marauding bandits by flinging fruit from your catapult! Make sure you use the right power and angle so you'll knock them out quickly though!

Kingdom of Catapults is one of four games for the new BBC Two series "The Code" about maths in the world around us, presented by Marcus du Sautoy and starting on Wednesday 27th July at 9pm! Check out The Code at http://bbc.co.uk/code

The Code is *also* a treasure hunt - we've hidden a valuable and unique treasure somewhere in the UK, and the clues to find it are within the show itself, in Lost-style symbols and messages, in online games, puzzles, and real-world challenges. Can you crack The Code?

Check back for our next three games, each of which will contain a clue for the treasure hunt!
