Quick instructions

You must search for relationships between words and phrases in a piece of text.

You will be given a word or phrase and you must look for any evidence of it appearing earlier in the text. An example of this would be:

Sherlink Holmes went to the shop. He got some tobacco for his pipe.

The word in orange refers to "Sherlink Holmes".

You will be asked whether you agree with another detective's decision. An example of this would be:

Sherlink Holmes went to the shop. It was closed.

The word in orange refers to the phrase in blue so you should agree with this decision.

Here are a few game stats for you number junkies. We have over 1.5 million examples of human language in the database submitted by 3500 players, a collaborative effort of over 2700 hours or 112 days. On average players are quicker to disagree with other players than to agree. Exported data from the game shows that the combined answers of players gives a very high quality result. A huge thank you to all detectives.
