Concentration (game show)

Concentration is a venerable TV game show based on the children's memory game of the same name.

What's a rebus?

In all versions, two contestants competed to solve a rebus behind doors of numbers. For instance:

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

• Picture of a 2 of clubs = "TOO"
  
• "LI" plus a picture of a cash register till = "LITTLE"
  
• Picture of a hand holding up two fingers = "TOO"
  
• Picture of a hen "lay"ing eggs plus "T" = "LATE"
  

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

equals "Too little, too late."

~ ~ ~ ~ ~ ~ ~ ~ ~ ~
