At Ostrovzl (ostrovzl.cz), we believe transparency is fundamental to maintaining your trust. This page explains how we monetize our website and how our affiliate relationships work. We want you to understand our business model so you can make informed decisions when reading our casino reviews and recommendations.
Ostrovzl may earn affiliate commissions when you click on links to online casinos and gambling operators featured on our website. These are special tracking links provided by casino operators and affiliate networks. When you click these links and subsequently create an account or make a deposit at a casino, we may receive a commission at no additional cost to you.
Your experience and pricing remain identical whether you arrive at a casino through our affiliate link or by visiting their website directly. You will not pay more, and the casino will not charge you differently. The commission we receive comes from the operator's marketing budget, not from your account or winnings.
Ostrovzl partners with reputable online casinos and affiliate networks operating legally in the Czech Republic and European markets. Our affiliate relationships are:
Despite our affiliate relationships, all casino reviews published by Thomas Berg, Ostrovzl's founder and primary reviewer, are conducted independently and based solely on merit. Our affiliate income does not influence which casinos we review, how we rate them, or what recommendations we make.
In fact, we review many casinos from which we do not earn affiliate commissions. We also publish detailed reviews of operators we recommend against, regardless of potential lost income. Your access to honest, unbiased information is more valuable to us than short-term commission earnings.
Thomas Berg has spent years researching online gambling regulation, casino operations, and player protection mechanisms across European markets. His reviews reflect genuine expertise in evaluating casino quality, game selection, licensing validity, bonus terms, and customer support. Each review is conducted according to our standardized methodology and personal testing.
Every casino featured on Ostrovzl undergoes rigorous evaluation based on:
This methodology is applied uniformly to all casinos, regardless of affiliate status.
Affiliate links are clearly marked on our website where applicable. Look for disclosure language such as "affiliate link," "sponsored," or similar indicators near casino links and buttons. If you have questions about whether a specific link is an affiliate link, please contact us directly.
We understand that recommending casinos for a living creates potential conflicts of interest. We've structured our business model to minimize this risk. We prioritize your experience and our reputation above commission earnings. Negative reviews cost us potential income but serve you better.
If you ever feel our reviews lack objectivity, or if you have concerns about our affiliate relationships, please contact Thomas Berg directly at the contact information provided on our website.
This disclosure is current as of 2026. If you have questions about our affiliate relationships, review methodology, or editorial independence, we encourage you to reach out. Transparency builds trust, and your questions help us improve.
