I do think this discussion is more of a "Home Poker" discussion since it's about non-serious, non-casino games that are usually played with friends for coins.
Since you also posted about Super Hold'em and you find these kinds of games interesting, I'll list a whole bunch of games that we've played (friends and family) over the years:
Black-bottom Shipwreck:
7 card stud, low card in the hole (and all else like it) is wild, high spade in the whole gets half the pot.
So if I have (34)377T(Js), I have two wild 3's, giving me 4 7's.
If you have (4As)488T(2), you have one wild 2, giving you 8's full of 4's. You've been "Shipwrecked" by the deuce on 7th since it ruined your wild 4's. However, you still get half the pot because your Ace of spades down is higher than my Jack of spades down.
7/27:
Each player starts with one face-down card and one face-up card.
2-10 are face value, J/Q/K are 1/2 point, and aces are 1 or 11.
There's a betting round, then each player in turn can either hit or stay.
After each round of drawing cards, there's a new betting round.
After a round passes in which everyone stood, there's a final betting round and then showdown.
Closest to 7 without going over gets half the pot, closest to 27 without going over gets the other half.
If at any point you exceed 27 (bust), you must muck your hand immediately.
If you make both 7 and 27 exactly (e.g. 5AA), you scoop the whole pot at showdown, even if someone else has 7 or 27.
2/22:
Same as 7/27 but everyone starts with one face-down card, and it's closest to 2 and 22.
7/27 and 2/22 variants: Black cards don't count (worth 0) or red cards don't count.
Follow the ***** (Queen):
7-card stud, but all queens are wild.
If a player is dealt a queen, the next card dealt is wild (and all others like it).
If another queen is dealt, the same thing happens and the previous wild card is no longer wild.
Players may choose whether they want their 7th card up or down.
If no face-up queen is dealt, then you re-deal a new hand with all remaining players.
Guts-style games:
Guts:
Each player is dealt 2 cards. After sufficient time of looking and making a decision, each player holds their cards in front of them, above the table.
On a count of 3-2-1 guts, players either drop their hand or hold onto it.
Remaining players flip their hands over. Highest hand wins the pot, and the losers have to each put in the amount of the pot for the next hand.
example:
All 6 players ante 25 cents, for a total pot of $1.50
Bob, Jane, and Mike all hold their cards.
Bob flips over 44, Jane AT, Mike AK. Bob takes the $1.50 pot; Mike and Jane each pay $1.50 to the pot, resulting in a $3 pot for the next hand.
If only two players hold and they tie, they each have to pay the pot.
If only one player holds, they have to beat the next 2 cards off the top of the deck. If they do, they win the pot and the game ends. If they lose, they have to match the pot.
If the player ties the deck, they have to pay double the pot (basically, they're paying both their own share and the deck's share).
Kings and Little Ones, drop style:
Each player gets 4 cards.
Same "drop" mechanic as above.
All players who held can discard and draw 0-4 cards.
All kings are wild, and the lowest card in each person's hand is wild.
If only one player stays, 4 cards are dealt off the deck face up, the non-competing players decide together what to discard, and cards are drawn. Then the staying player flips their cards up. If they win, they take the pot and the game ends.
Fours and Whores, drop style:
Same as Kings and Little ones, but 4's and Q's are wild.
Fargo (everyone's favorite):
All players ante.
2 cards are dealt to each player.
The player to the dealer's left can choose an amount to bet "from the pot". So if there's $1.50, they can wager between .25 - 1.50.
If they choose to wager, each player in turn has a chance to compete against them. If they do, they trade cards (without revealing to anyone else) to see who wins, then trade back. The loser pays the wagered amount to the pot and also to the player (if you wager $1 and lose, then you pay the pot $1 and the opposing player $1).
If no one goes with you, you take the wagered amount from the pot and the game continues (as long as there's still money in the pot).
Then a third card is dealt and the player 2 to the left of the dealer has a chance.
Then a fourth is dealt and the next player has a chance.
Repeat until it's the dealer's turn. If there's still money in the pot after the dealer's turn, then everyone re-antes and the deal passes to the left.
