Subject: Kill the duck
Body: The game of kill the duck is simple. One player draws a duck, and is defense. The other player draws objects that would kill the duck. That player is offense. The two players alternate turns, trying to draw objects that would kill/save the duck. Multiple users may join the offense/defense. The official rule list (it's complicated):
• If the offence’s turn ends with no threat on the duck, the defense wins
• If the defense’s turn ends with an object killing the duck, the offence wins
• You may not edit another player’s drawing, nor the duck, unless you draw an object that would cause such edits to happen.
• You may not draw two objects, unless one object would arise as a direct consequence of another. For instance, you cannot draw a pirate ship and a death star, however, you may draw a death star and a laser, as the laser is a direct consequence of the death star. Destroying the death star would result in the destruction of the laser.
• You may only clear the stack at the beginning of your turn.*
• One object cannot attack two other objects simultaneously.
• You can not move the duck.
*The stack is the order in which objects were drawn, in reverse. So, if you chose to clear the stack, the last object drawn has it’s effect, and so on, until every object has caused it’s effect. You may stop clearing the stack half way, but you cannot disturb the timeline.
