Randomness of Lotto Lucky Dip: summary of findings (2005)

The National Lottery Commission has asked the Centre for the Study of Gambling at the University of Salford to verify that the U.K. National Lottery Lotto Lucky Dip algorithms show no evidence of producing non-random results. The purpose of this piece of work is to establish whether there are any elements of non-randomness within the Lotto Lucky Dip facility associated with the U.K. National Lottery. Specific objectives are to test that:

there is equality of frequency for each number chosen;all selections are independent of preceding outputs;there is no evidence of non-randomness for Lucky Dip selections within the draw-based Lotto game in the retail network.p.
In order to test these hypotheses, details of 25,000 sequential Lucky Dip combinations generated for Lotto customers from 50 representative retail terminals were requested and supplied.
