Cool Facts
One player chooses. The "spy" picks any object they can see right now, but keeps it secret from the other players.
First letter clue. Instead of describing the object, the spy gives just the first letter by saying "I spy with my little eye something beginning with..." followed by that letter.
Everyone guesses. The other players take turns asking "Is it this?" about different things in the room or car until someone guesses correctly.
Perfect for travel. I Spy became super popular as a car game because you can play it anywhere with an endless supply of things to spy on out the window.
Quick and simple. There are no complicated rules or equipment needed, just eyes, a brain, and something to look at.
