Players navigate these differences by researching and choosing games with favorable rules that offer lower house edges. Additionally, they can employ optimal strategies tailored to each game variant, such as basic strategy in blackjack or optimal play in video poker, to further reduce the house edge and increase their chances of winning. By understanding the rules and odds of each game variant and implementing strategic gameplay, players can maximize their overall returns and enjoyment while minimizing the impact of the house edge.
