They are placed on the ground mats in the square slots and can be stacked on top of each other when captured from enemies and you do not have an empty square left on your mat.
When stacking a tower, you need to draw a card from your deck face-down and place it below the captured castle tower as shown below.

Look for more information in Capturing towers.
The catapult is used to shoot ammo into opponent towers. It must be always placed at the furthest corner of your own mat from the middle. You may use the game box to increase the height from where you shoot.
The ammo is stored in a convenient pile for everyone to use. The game ends if no ammo is available from the pile.
These are the cards used in the game. They are placed in a face-down deck, used from the hand after they are drawn, and discarded face-up.
You may draw a card from your deck when you lose a tower if you have cards left in your deck. If you do not have cards left in your deck then shuffle your discard pile and form a new deck.
