I spy is a guessing game where one player (the spy or it) chooses an object within sight and announces to the other players that "I spy with my little eye something beginning with...", naming the first letter of the object. Other players attempt to guess this object. It is often played as a car game. Rules One player is chosen to be the Spy, and they silently select an object that is visible to all the players. They do not announce their choice, and instead say, "I spy with my little eye something beginning with ...", naming the letter the chosen object starts with (e.g. "I spy with my little eye something beginning with C" if the chosen object is a cow). Other players then have to guess the chosen object. Traditionally players ask directly about particular possibilities ("Is it a tree?"). Once a guesser has correctly identified the object, they become the Spy for the next round and the game starts again. If younger children are playing who are not so good at guessing, the role of Spy can be passed around in a set order. The Spy cannot change the object once it has been chosen. The game relies on trust as the Spy is the only person who knows whether the guessers are correct or not. Variants In situations where players are traveling from place to place through the course of the game, such as a car journey, players may agree that any chosen object should remain visible, rather than an item such as a particular street sign which will only be visible for a few moments when the game begins. Players may also agree to decide if the objects will be all outside or all inside the vehicle. Some versions of the game allow players to narrow down the search with yes-or-no questions such as "Is it on your left?" or "Is it an animal?". The Spy can also offer clues if the guessers are stumped, such as saying ‘Hot’ when a guess is close or ‘Cold’ if it is not. An alternative version is substituting the initial letter for an adjective such as the colour of the object (e.g. "I spy with my little eye something blue"), while another is to say "I Spy with my little eye something that sounds like". Some sites such as About Parenting describe the letter version as the
