If the ammo landed inside another player's tower, and stayed there, you may immediately take that tower piece and add it your Player Mat.
The player whose tower you just took may draw a card from their own deck. Then your turn ends - pass the catapult to the next player on your left.
If you have an empty square on your mat, then the tower must be placed into it. If you have multiple empty squares you may choose which one you want to place the tower into.
If you don't have an empty square on your mat, you must stack the tower on top of another tower on your mat. To do this, you must take the top card from your deck and place it on top of another tower without looking at it. Then place the acquired tower on top of this card.
Note: if you don't have any cards in your deck, then you must give a card from your hand instead! The card is still placed face-down on the tower.
If your shot went inside a tower that is stacked on top of another tower you only take the top tower - not the entire stack! Only if you used a card Strong Shot you take the whole stack.
When you take only the top tower that was stacked on top of another tower, place the card that was underneath it into the respective deck's discard pile.
Do not take ammo from the tower! It will remain inside the tower for the rest of the game.
If you need a draw a card but there are none left in your deck, shuffle your discard pile face-down and create a new deck. If there are no cards in the deck or discard pile, you may not draw a card.
If you miss and the ammo does not land inside another player's tower, your turn is over. Return the ammo that was just shot to the supply pile and pass the catapult to the player on your left. They will take the next turn.
Note: if the ammo went inside the tower, but bounced out, this does not count! It must stay inside the tower in order for you to take it.
