My daughter and I made this one up over the last week or so, and have spent every night testing and refining the rules. Check it out.
UNO GO FISH! Official Rules
This works well with 2 to 4 players.
Deal seven cards to each player.
The remaining cards are spread out into a "Lake" in the middle of the table.
Player to the left of the dealer goes first.
Object of the game is to complete Sets of cards by asking a player if they have a needed card.
example: if you're attempting to complete a set of "2"s, you would ask a player if they have any "2"s. If the player has any "2"s in their hand, they must give you one.
You may not ask for "Wild" cards or "Wild +4" cards.
You may not ask for a specific color card.
A Set consists of four cards of the same type, one of each color.
When you have a Set in your hand, you may lay them out in front of you.
Sets may consist of four of the same Number cards, Skips, or Reverses,
but must include all four colors.
You may use one "Wild" card per set, but if another player can complete your set with the missing card, they may steal your set and must immediately return the "Wild" card to the bottom of the "Lake" after laying out the Set that they stole.
"Wild +4" cards may not be used in any Sets except a Set of "Wild +4" cards.
If you complete and lay out a set of "Wild +4" cards, you must immediately draw four cards after laying out the Set.
Likewise, when laying out a Set of "Draw 2"s, you must immediately draw two cards after laying out the set.
Skip Sets and Reverse Sets act like regular Uno:
A Skip set causes the play to skip the next player,
and a Reverse set causes the play order to reverse.
If a player runs out of cards, they must draw seven cards from the "Lake".
If less than seven cards remain in the "Lake", the game ends.
The game also ends if the "Lake" of cards is exhausted.
At this point, all players must tally up their scores.
Your score equals the value of your Sets, minus the value of all cards left in your hand. Sets must be laid out in front of you before the end of the game, or they do not add to your score.
Numbered cards are worth their number. A "5" card is worth five points, for example.
A Set of "Draw 2"s is worth 40 points.
A Set of "Skip"s or "Reverse"s is worth 60 points.
A Set containing a "Wild" card adds 25 points.
A Set of "Wild +4" is worth Nothing, but prevents you from losing points for those cards.
Subtract the value of all Numbered cards from your score.
Subtract 10 points for each "Draw 2" left in your hand.
Subtract 15 points for each "Skip" or "Reverse" in your hand.
Subtract 25 points for each "Wild" card in your hand.
Subtract 50 points for each "Wild +4" in your hand.
Highest score wins.
