A picture quiz of chocolate bars, created by Ken's Quiz, which was shared by TV host Richard Osman has become a hit - with 2.1k likes and almost 300 retweets.
The fun quiz is ideal for testing your knowledge this World Chocolate Day, which falls on 7 July as it is thought that this day celebrates the introduction of chocolate to Europe in 1550.
As well as being World Chocolate Day, online quizzes have become a popular part of lockdown life, with many of us meeting up with friends over video calls to take part.
Emoji quizzes and guessing games are also popular ways to pass the time.

Richard Osman tweeted the chocolate bars picture and challenged followers to beat his 16/20 score.
One Twitter user replied: "Wow harder than I thought, but probably because I inhale my favourite chocolates and never take the time to decipher them ." While others tweeted that they now fancied chocolate.
The tweet proved so popular that the Ken's Quiz website was temporarily unavailable, though it's back now.
Richard also tweeted the answers, which can be seen here.
