Go Fish (or simply Fish) is a simple card game. It is usually played by two to five players, although theoretically it can be played with up to ten. Using a standard 52 card deck, seven cards are dealt to each player, or nine if there are four or fewer." The remaining card pack is shared between the players, usually sprawled out in a non-orderly pile referenced as the "ocean" or "pool".
Players that do not have the requested cards tell their counterparts to 'go fish', which means the player must choose one card from the pool of cards at the center. The player whose turn it is to play asks another player for their cards of a particular rank. For example, "Steve, do you have any threes?" Players can not ask for a card they are not holding.
The recipient of the request must then hand over all cards of that rank. If the call was successful, the same player has another turn. If the player who was asked has no cards of that rank, they say "go fish", and the asking player draws a card from the ocean.
