Blackjack (house version)
Uno with cards. A is wildcard, 2 is +2, 8 is skip, ♣️♠️J is +7, ♥️♦️J cancels it, Q is reverse. Play the same suit or same number as the card before you. Stacking/runs allowed. Pick up and play.
Go Fish
Get sets of four. On your go, ask for a number and correctly guess the suit. At the end, one wrap-up round where you need to get all the sets of four in order, ace onwards. If you miss, it's the next person's go.
Whist
Not sure about the numbers in these rules, check. A longer game good for 3-6 players. The aim is to get as many points as possible. First, remove all cards ≤6 (not including aces). If there are $n$ players, there are $n$ rounds of one, followed by a single round of two, three, …, seven. Then, $n$ rounds of eight, then a single round of seven,…, two, and finally $n$ rounds of one again. In each round, deal out that many cards to each person. If there is a pile remaining (i.e. always except for the rounds of 8) turn over the top card, and that's the trump card. The aim is to make correct bets about how many hands you will win. In the rounds of one, each player holds their card up to their forehead so they cannot see it. They then, starting from the first player, each make a bet about how many hands they will win that round (i.e. 0 or 1, with the caveat that the final player cannot pick the option which would make the sum of the bets equal to the round number). They then show the cards. The highest card wins the hand, except the trump suit beats all other cards, and highest trump wins. This continues for each round. In the rounds of eight, there is no trump card. You make all bets before starting to play each set of hands. The person who starts rotates.
Skulls
Good for ≥3 players. Aim of the game is to win two rounds, or be the last player left. Each person gets four cards: 3 of one set (“flowers”, eg non-picture cards) and one of another (“skulls”, eg picture cards, aces). First, every player puts down a card from their hand, face down. Then, the first player can either put another card down, or make a bet as to how many flowers there are on the table. The next player does the same, unless the first player made a bet, in which case they have to raise or pass. If someone cannot play, they must make a bet. Once everyone has passed on a bet, the person who made it must match the bet, by turning over cards on the table, to get enough flowers, without getting any skulls. They must first turn over their whole pile, before touching other people's cards, and they must start from the top each time. If they match their bet, they've won a round. If they get a skull, the person whose pile it was randomly chooses one of their cards to remove.
Spoons
Good for ≥3 players. Aim is to make a set of four of the same number. Give five cards each, in their hand. First player has the rest of the deck. They pick up a card, and can either swap it with one in their hand, or pass. They give the card to the next person, who does the same, and so on. When one person has four of the same, they pick up a spoon, or do some other action. Last to do the action is out of the game.
Pallas
9 cards each: 3 down, 3 up, three in your hand. Aim is to get rid of all your cards. You can add one card at a time into the central pile, and it has to be the same as or higher than the top card. Some power cards: - 2 resets the deck, lowest card, anytime - 3 is a glass card, passes your go, anytime - 7 means the next person plays <7 instead of >7, only in order - 8 skips the next person, anytime - 10 destroys the central deck, you take it out of the game and it's your go again, anytime - Q reverses the order, anytime If you can't play, pick up. You can only play the cards in your hand at the start, only once those are finished can you touch the face-up cards, and only when they are done can you touch the facedown ones.
Speed/slam
Good for two players, aim is to get rid of all your cards. Split the deck, and lay out the cards in 4/5 piles with 1,2,3,4(,5) cards in each pile, with all cards face down except the top one. On “go”, both players turn over a card from their remaining pile into the middle. You need to get rid of the four/five piles by adding cards to the central two piles. You can only add cards if they are the same, one above, or one below, the cards in the middle. Go as fast as you can. First to finish their piles slams the smaller pile in the middle; they then get that pile, and the other person gets the larger one. You can slam when the other person finishes too.
Cheat
Can play one above, one below, or the same. Successful accuser or wrongfully accused continue play.
Irish Snap
First person flips their card onto the central pile and says 'ace'. Subsequent players flip one card and say the number after the previous person. Snap if two cards have the same number, if the number you say and the number you flip are the same, or a 7 comes up. Last snapper or incorrect snap picks up pile. Snap when you run out of cards to add a new rule or remove one, and keep playing, just saying numbers. Good house rules are e.g. cards add to 10, or alternate cards match.
