The task of the spider is to kill the survivors before they escape the Cabin. Every round a spider is chosen when a Robloxian gets chosen to become the spider. Once the game begins, the players have 25 seconds to prepare before the spider spawns in the map.
There aren't a lot of rules to remember for Spider Wars, simply move two legs per turn. The only limitations are you cannot move the same leg twice during one turn. If you are moving a dangling spider you must move the free leg backwards and it counts as your full turn.
