your object is in an array with many other
you only need to implement one method obj.turn(context)
all object will run at the same time in a concurrent environment with a timeout
they will have to corrupt other object
once object is corrupted. code linked to the array will kill it

there is also terrain effect

to make sure it is fair
loop will deepcopy every object before running it. so they corrupt a copy
if you die from one or more hand. you die. but you had chance to kill other anyway.

place are a simple validation were your object must comply. it will differ from one place to another
