About Our Contributors

Dear punters! My name is Jack Reeve. I'm a UK-based journalist focused on sports and gambling events. Currently, I'm investigating the influence of the UKGC and Gamstop scheme on problem gamblers. That's why I've decided to cooperate with this online gambling portal to understand the flaws of the scheme and things that punters don't like about new laws. As my works are cited by famous newspapers like, Business Matters and MarketWatch, you may notice that I'm not the last author in this industry. Hopefully, the readers of will notice the value that I bring to the articles and tell me more ideas or their concerns via e-mail or contact form.
