These poker games are based on five-card draw, but add or change something to make it new. If you're playing a dealer's choice game, they're fun to add to the mix.
In Jackpots, a player has to have a pair of jacks or better in their original 5-card hand to start (or open) the betting. If no one has at least a pair of jacks, everyone folds their cards, antes again and a new hand is dealt. The cycle continues until someone gets dealt a pair of jacks or better and opens the betting.
This game is almost the same as regular five-card draw, except everyone gets to draw new cards twice instead of the usual single draw. Theres also an additional round of betting following the second draw.
Lowball (sometimes called California Lowball) is just five-card draw where instead of the highest hand winning the pot, the lowest hand wins it. The lowest hand, depending on what game you're playing may be defined two ways. Usually in games with a low hand, straights and flushes don't count against a hand being low, so A-2-3-4-5 is the lowest hand. The ace to five straight is also called "the bike" or "the wheel."
In some home games, however, they define the lowest hand as the "worst" hand, with straights and flushes counting. In that case, the lowest hand is A-2-3-4-6, not of the same suit.
Take double-draw, add another draw with another round of betting, and you've got the triple-draw part of this game. But this game is also played for low, only the best low hand here is 2-3-4-5-7. Straights and flushes do count against you, and aces are always high.
