As rates of Internet gambling participation increase worldwide, so too does the need to understand how people engage in this form of gambling. This study represents the first examination of actual Internet gambling records within Iceland, a Nordic country with an active Internet lottery market that imposes strict regulations on gambling operator licenses. We summarized electronic betting records of a cohort of subscribers to the Internet betting service provider Íslensk Getspá. We observed that the typical subscriber bet approximately 3 days per month and made fewer than two bets per gambling day, each worth approximately the equivalent of $4 US. Subscribers lost the bulk (96%) of the amount they wagered, for a total loss of approximately $40 across the 2-year window of observation. Although these observations do not support the view of Internet gambling as an activity that is inherently risky for the typical subscriber, we did observe discontinuity across the distributions of gambling behavior, with the top 1% of subscribers making more than three bets per day.
随着全球范围内网络赌博参与率的上升，了解人们如何参与这种赌博形式的需求也在增加。本研究首次对冰岛的实际网络赌博记录进行了考察，冰岛是一个北欧国家，拥有活跃的网络彩票市场，对赌博运营商执照实施严格监管。我们总结了网络博彩服务提供商Íslensk Getspá的一群订阅者的电子投注记录。我们观察到，典型的订阅者每月大约投注3天，每个赌博日投注少于两次，每次投注价值约相当于4美元。在为期两年的观察期内，订阅者输掉了他们投注金额的大部分（96%），总计损失约40美元。尽管这些观察结果并不支持将网络赌博视为对典型订阅者具有固有风险的活动这一观点，但我们确实观察到赌博行为分布存在不连续性，前1%的订阅者每天投注超过三次。
