A wall of 480 colours. One person sees the square everybody is hunting and gets one word, then two. Everyone else puts a marker down. 3 to 8 people, about 15 minutes.
Very nearly language-free, and that is exactly why it is on the shelf. A cue is one or two words and the reasoning is about colour rather than vocabulary — so at a table where half the room is working in their second or third language, nobody is playing a game about English.
It also gives everybody something to do at once: every guesser places a marker every round, so a table of eight has eight people acting rather than seven watching one.
