variant to the colour-based game. This site has the form "I spy something, and it's blue" as the traditional version, deeming "I spy with my little eye..." as an alternative. Having clues based on an object's shape is another alternative, while quick thinkers can deliberately choose objects that can only be seen for a limited amount of time. Howcast notes that looking at an object when announcing its colour is a "dead giveaway" so this should be avoided. Another variation that encourages language development involves the Spy giving various descriptive clues, such as describing a watch as "something made of metal and glass that makes a quiet noise". Purpose About Parenting notes, "I Spy is one of the first games that most children learn to play", and recommends the game for "doctor's offices, restaurants and other places where you sometimes have to wait with kids", but discourages its use in moving cars. The game "requires no equipment and can be played almost anywhere and with as many people as you want", both with adults and children, though a minimum of 2 players is required. I spy is often played with young children as a means to avert boredom in long journeys. A survey by British insurance company Direct Line found that 58% of families played I spy, and 65% of the parents consulted had played it on journeys as a child. Raising Children Network recommends a colour-based variation of the game for pre-schoolers, and a variation encouraging the learning of sounds for school age kids ("I spy with my little eye something beginning with f-f-f. What do you think I’m looking at that starts with that sound?") The fun comes with trying to discover the identity of a mysterious object. The game allows kids to practice their oral/aural skills. Mary Tomczyk argues I Spy is a clever reasoning game that allows kids to solve puzzles, and gives them an opportunity to "'stump' Mom or Dad". She says children "learn to be more observant about the world around them, learn about colours, shapes, and textures, and use logic and reasoning to draw conclusions". She recommends it for preschool and kindergarten kids. Despite its simplicity and repetitiveness, the game grows a child's vocabulary and can also serve as a distraction for an impatient child. Howcast argues " It will keep their minds occupied just about anywhere." The game can be played in
