His design also incorporated symbols such as spades, hearts, horseshoes, and liberty bells in place of the poker symbols, making it easier for players to find matching combinations and win.

However, manufacturers would weight particular symbols to increase the chances of them appearing on a payline as opposed to other symbols.
