This study examined the link between age, gender, and gambling intensity among people who use electronic gaming machines in Norway. Gambling intensity was measured using theoretical loss. This study used data provided by Norsk Tipping on 195,318 customers who played an electronic gaming machine called Multix between 2013 and 2018. The researchers examined differences between groups with different gambling intensity. Low-intensity gambling was defined as theoretical loss at the 25th percentile. Average gambling participation was defined as theoretical loss at the 50th percentile. High-intensity gambling was defined as theoretical loss at the 90th percentile. The findings show age and gender differences in gambling intensity. Older age was associated with greater gambling intensity across all percentiles. Participants aged 70+ years had the highest theoretical loss at the 25th percentile (500 NOK) and at the 50th percentile (5,280 NOK). The second oldest age group (60–69 years) had the highest theoretical loss at the 90th percentile (15,343 NOK). Men showed greater age-related differences in gambling intensity compared to women. At the 90th percentile, women aged 18–29 years had twice as high gambling intensity compared to men aged 18–29 years.
