What does an octopus mean in football? Eight points are scored in an octopus  six for the touchdown and two for the conversion  and so this bet type was named after the eight-legged creature from the depths of the sea.
On the face of it, the rules are simple. To paraphrase: anyone involved in the game must not bet on any football match, anywhere in the world. However, the FA was mindful of the fact that some club owners were inherently involved in betting, via their business interests.
