The rolling of four six-sided dice, shortened to 4d6, underpins a lot of random elements in Mr Football. Most sports games keep the mathematics behind the screen, but Mr Football makes them explicit. This is most notable in the probabilities of drawing different cards from the player packs. In this rulebook, every gacha pull will come with fully exposed probability tables.
4d6 rolls in matches for contests refer to a particular table of results to produce different outcomes, which can lead to not just a loss or win of the contest but bypassing further plays in the chain.
