Players must agree beforehand whether you can counter +4s with +2s, and if they're restricted to the color that the +4 user picked or not.

If you can't play a card, you buy only one card and if you can't play it, you skip that turn.

If you have multiple cards of the same number (even if different colors) you can play them all at once (but it must be at once, if you didn't realize you had a stack of similar cards that's your loss)

You cannot stack sequential number cards (that means no playing 1, 2, 3, 4, 5... at once even if they're the same colors)

Jump in and stack 2 on 2.
My personal gripe is most deny 4 on 4 can not be stacked but I disagree.
Even the actual UNO video game has 4+4 stacking (with the modifier. But there are modifiers disabled by default that are default-rules in the physical game)

I have played Uno once in my life. (I'm not opposed to it. My family just played 500 Rummy when we wanted to play a card game. I never even heard of Uno until the one (edit: or uno) time I played it. My wife recently informed me that this is in some way unusual or, to use her words, "so weird.")

So I guess my house rules these days (it's been twenty-some years since that one time) would be "during each turn, desperately search the rulebook to figure out what to do."

I play by challenge and double down/jump in rules.

Challenge rule: if the person plays a wild and the next player decides to challenge it, the person being challenged shows their hand to the next person in line, and if there was another card that could have been played instead, The person who played the card has to either draw two cards, or if it was a wild draw four, they draw the cards instead. However they were wrong, then they draw the penalty cards (so if it was a draw 4 they draw 6, and a standard wild they draw 2)

stacking/double down/jump in: If any player has a card that is identical to the current revealed card, they can jump in, and play that card as long as the next player has not started playing their turn. When a player jumps in, the turn order starts as if they had just had a turn, so it would be the next person from their position. If the card was a card that required a player to draw, the effect of the original card is cancelled, unless the player jumping in was the player that would have received the cards, in which case the effect is stacked and given to the next player(so a draw 4 becomes a draw 8), This effect can continuously be stacked as long as someone else doesn't jump in or the person doesn't have an identical card to continue stacking.

We play speed Uno. If you have the identical card as the card that's played, you can lay it down if you get it to the pile before the person whose turn it is lays down theirs. Play then continues from you.

If you can't play on your turn, you keep drawing until you can.

We don't play these rules every time, but they're incredibly fun.

On a 0, we all swap hands in the direction of play.

Placing a 7 allows you to swap hands with a person of choice.

+2 cards can be stacked, the first person without a +2 takes all of them

Strict rules, buddy. If it's your turn and you ask if it's your turn, +2. You go out of turn? +2. Everyone's looking at you weird? Believe it or not, +2.

Doubles and stacking.

I'm not playing with that "pull until you draw a playable card" rule. It can be a wild card, but as a general rule, nah.

We have a custom Fuck Uno card that is +12.

Thats a good rule. Im a total wild sandbagger.

I've seen a variant that allows consecutive/same cards to be played in one go, so for example 123456. People ended up finishing their cards in very few turns.

if you land on free parking you get to keep the discard pile

Back with my family growing up, we sometimes played Uno with Cheating.

Basically this meant you were allowed to cheat in any which way (playing on somebody else's turn, playing mismatching cards, playing several cards at once, drawing too few cards, hiding cards somewhere...). BUT if you were caught before the next player made their move, you had to undo the cheating (e.g. take back the cards), draw an extra card, and you forfeited your turn.

This sometimes led to extreme fun, particularly late at night when everybody was tired and cheating was more likely to go unnoticed.

Everyone is required to wear a red clown nose during the game... and nothing else!

On those blank wild cards, we have it so you have to roll 1, 2, or 3 D6 depending on the card, and draw that many cards

We play +2s, Reverse, and +4 wilds can be stacked. A +4 being played needs a colour declaration, and a +2/reverse of that colour can continue the stack.

Usually this means +4 will kill the pile and the unfortunate sod is picking up 6, or 8, or whatever... But sometimes, they magically have the correct Reverse, or +2 and escape with their life.

An alternative side rule we play is chains. I play a green 3, I can immediately play a green 4, then a red 4... Until I can no longer play matching number, or consecutive colour, or effect card.

Mostly because we used to play a card game we called Blackjack, that is basically Uno, but with chaining. Aces were wild, 2s were pick up 2, 8s were miss a go, Jacks of spades/clubs were pick up 7, Jacks of hearts/diamonds did something else.

My got take - if you're not playing with stacking draw cards, you're playing Uno wrong

Draw Fours and Draw Twos stack. You can play Reverse or Skip in response to Draw cards.

Lots of fun when the draw chain gets up to the 20s and everyone is desperately burning Skips and Reverses to avoid it.

if there are only 2 people we get rid of the draw 4 cards

We only have one house rule: anyone who suggests Uno gets beaten.
