Conkers has been voted the greatest playground game of all time.
Second place in the poll of 3,000 adults was the Rubiks Cube which has sold more than 300 million since 1979.
In third place was the yo-yo, which first became popular in the 1920s and made a resurgence in the 1990s.
Hopscotch, the oldest game in the top 20, was fourth. It originated in Britain early in the Roman Empire as a training exercise for foot soldiers.
The 1990s craze Pogs – a game involving decorated cardboard discs – is at number five.
A spokesman for Debenhams, which carried out the poll, said: ?Playground memories are such a big part of our childhood and everyone can remember school breaks playing with the latest toy or game of the moment.
?Conkers are a classic school ground craze and every generation can reflect on happy memories collecting conkers and preparing them for playground contests.
?Having the latest trend is so important to kids and all the fads in the top ten all evoke fond times of hours spent playing with them.?
Japanese cartoon Pokemon was voted in at number six followed by the classic game of Marbles. Tamagotchi – digital pets that need feeding, cleaning and putting to bed – came eighth.
Roller skating and skate-boarding completed the top ten. Other crazes to feature in the top 20 include the cult card game Top Trumps at number 12.
