How we score: We evaluate each listing using our weighted methodology (0–100). See the full criteria on the Methodology page.
Traffic & Reach
JohnSlots attracts a broad European audience, particularly in Northern Europe and the UK. Its traffic is solid though not at the level of the largest global portals. Similarweb data showed roughly 22,000 total visits over a recent 3-month period, corresponding to a few thousand monthly users. The site’s global rank was around 1.3 million in mid-2025, reflecting a moderate reach. JohnSlots’ presence in multiple languages (English, Swedish, Finnish, German, Norwegian) helps it engage niche markets despite trailing top-tier competitors.
Reputation & Licensing
JohnSlots is known for only promoting properly licensed casinos and advocating responsible gambling practices. The site holds industry certifications such as the GPWA Seal of Approval, indicating adherence to ethical standards for affiliates. No specific gambling license is required for its operations, but JohnSlots has built trust through transparency and compliance with advertising regulations. In 2023, the platform became part of Gaming Innovation Group’s affiliate portfolio via acquisition, further underscoring its credibility and industry standing.
Bonus Portfolio
JohnSlots offers a comprehensive bonus variety primarily focused on slots, so players seeking sports betting or other verticals may need to look elsewhere.
UX & UI
The site delivers a strong user experience thanks to a sleek interface, clear navigation and availability in multiple languages.
Affiliate Support
JohnSlots’ affiliate support is adequate but not as extensive as some competitors.
Verdict
Overall, JohnSlots provides a comprehensive, trustworthy guide to slots and casino reviews with a user-friendly interface, offering a well-balanced experience.
