A game of Worms (regardless of version) involves teams of worms trying to kill one another, until all members of opposing teams are dead. To do this, a variety of weapons are available.
The strategy enters the game when a player must decide which course of action best advances his team's interests. Choices may include which enemy worm to attack, which weapon to use, whether to use one's turn improving one's position or one's arsenal, rather than attacking, how much damage one can inflict upon one's own worms in attacking the enemy, etc.
Games take place on a cartoonish, two-dimensional landscape. Much of the landscape can be destroyed with exploding weapons.
A worm is killed when its energy level is reduced to zero, or when it drowns in the water that surrounds each landscape.
