“…Chagas and Gomes ( 2017 ) reported that initial studies on lottery tracking data relied on the same database ( Bwin ) and later ones were limited to a few databases and focused on very narrow time frames such as account opening or closing. More recently, additional gambling operators (e. g., ComeOn Group, Íslensk Getspá, Kindred, Leo Vegas, Norsk Tipping, Svenska Spel and win2day ) have made their databases available for researchers to study gambling behavior (Auer & Griffiths, 2013 , 2016 , 2017 , 2018 , 2020 Auer et al, 2018 , 2019a , 2019b , 2020 ; Fiedler, 2011 , 2013 ; Gainsbury et al, 2012 ; Gray et al, 2015 ; Ukhov et al, 2021 ). These studies cover different forms of gambling and only a few include lottery gambling (e.g., Auer & Griffiths, 2013 , 2014 , 2016 ; Auer et al, 2018 ; Gray et al, 2015 ) and none of these studies used a player/consumer segmentation method, such as the one we used in the present study, for the study of lottery gambling or even studied the population of a southern European country.…”
