Abstract

Background and aims: Responsible gambling (RG) tools and initiatives have been introduced by social RG operators as a means to help prevent problem gambling. One such initiative is the use of mandatory play breaks (i.e., forced session terminations). Recommendations by RG experts for gambling operators to implement mandatory play breaks appear to be intuitively sensible but are not evidence-based. Methods: The present authors were given access by the Norwegian gambling operator Norsk Tipping to data from 7,190 video lottery terminal (VLT) players who gambled between January and March 2018. This generated 218,523 playing sessions for further analysis. Once a gambling session reaches a 1-hr play duration, a forced session termination of 90 s comes into effect. This study evaluated the effect of mandatory play breaks on subsequent gambling. Results: Compared to similar sessions identified using a matched-pairs design, results demonstrated that there was no significant effect of the forced termination regarding the amount of money staked in the subsequent gambling session or on the time duration of the subsequent gambling session. Conclusions: Although expenditure was higher in the subsequent 24 hr for terminated sessions, this is likely due to higher intensity gamblers being more likely to trigger mandatory breaks. Implications of these findings are discussed.
