The player asks the opponent to give them all cards of a specific rank, for example" "Give me your nines". In our game you do it by tapping  one of your cards. If the opponent has any of such cards, they must give all of them to the player who asked. Otherwise they say "Go fish!" and the player must take a card from the deck, by tapping it.

As long as the player is getting the cards they asked for, either from the opponent or from the deck, their turn continues.

If the player does not receive the card they asked for, the turn passes to another player.

If a player completes a "book" (four cards of the same rank), they are placed on the table in front of that player, face up.

If at any time a player is left with no cards, they get one card from the deck and the game continues.

The game ends when all the books are collected.

The player with the most books is the winner.
