The Relationship Between a National and a Multistate Lotto Game

Main Article Content

The United Kingdom National Lottery is a member of a lottery block that offers a weekly lotto game, known as EuroMillions, for which tickets are now sold across nine countries. The paper examines whether the game has cannibalised sales in the pre-existing national lotto game and whether, with both products in place, players treat them as substitutes or complements. No evidence is found of cannibalisation and UK Saturday Lotto and EuroMillions are found to be complements rather than substitutes.
