Use a standard 52-card deck
Shuffle the deck thoroughly
Deal 7 cards to each player
Place the remaining cards face down as the draw pile
Decide who goes first
On your turn, ask the other player for a specific rank you already have in your hand
You must already hold at least one card of that rank
Example: “Do you have any 7s?”
If the other player has one or more cards of that rank, they must give all of them to you
If they do not have any, they say “Go fish”
Draw the top card from the draw pile
If you draw the rank you asked for, you get another turn
If you do not draw it, your turn ends
After each turn, check your hand for any four-of-a-kind sets
When you have 4 cards of the same rank, lay them down face up as a completed set
Keep taking turns until the draw pile is empty and one player has no cards left
The game ends when all sets have been made
Count completed sets to determine the winner
The player with the most sets wins
If both players have the same number of sets, the game is a tie
