===Countdown===
A variant of 5-card draw with four rounds of betting. After the first round of betting, each player may choose to replace up to three cards. A second round of betting follows and then players may opt to replace up to two cards. Upon completing another round of betting, each player may replace one card of the cards in their hand. After a final round of betting, any remaining players show their hands, and the highest 5 card hand wins. When players draw cards to replace ones in their hand, they add the cost of the cards in the pot. The cost of cards doubles each round. For example, if the dealer says each replacement card costs $10 in the first round, then each card costs $20 in the second round, and $40 in the final round.<ref>{{Cite web|title=How to Play Countdown Poker|url=https://www.pokerrules.net/wild/countdown/|access-date=2022-02-10|website=www.pokerrules.net}}</ref>
