Daan Vermeer is an online casino review editor and slot testing analyst at greatwar.nl. He focuses on practical casino and slot testing, including registration flow, KYC verification, payment speed, withdrawal clarity, bonus terms, mobile usability, customer support quality and slot volatility behaviour.
Education
Daan studied Media and Information at the University of Amsterdam, where he focused on digital media, online platforms and user behaviour. He later completed a master’s degree in Business Information Management at Erasmus University Rotterdam, with attention to digital services, data-driven product evaluation and online consumer decision-making.
This educational background helps him review casino and slot pages not only from a content perspective, but also from the perspective of usability, transparency, payment flow and information clarity.
Professional background
Daan started his professional career in 2017 as a digital content analyst for consumer comparison websites. In that role, he worked with product comparison structures, ranking logic, user intent, page quality and the way complex product information is presented to readers.
Between 2019 and 2021, he worked on UX and payment-flow research for digital platforms. This included checking onboarding steps, account verification flows, payment screens, form usability, mobile navigation and user friction during transaction-based journeys.
Since 2021, Daan has focused on online casino and slot game reviews. His work combines editorial analysis with practical testing: opening accounts, checking KYC steps, reviewing cashier sections, testing small deposits and withdrawals where possible, reading bonus terms, contacting customer support and comparing desktop and mobile behaviour.
Casino review experience
In casino reviews, Daan pays attention to the full user journey rather than only the visible offer. He checks how long registration takes, whether identity verification is clearly explained, how quickly deposits appear, how withdrawal limits are presented and whether bonus rules are easy to understand before opting in.
He also reviews customer support response quality. This includes response time, clarity of the answer, whether the agent gives practical information, and whether the user is simply redirected to generic terms without a clear explanation.
Slot testing experience
For slot pages, Daan reviews RTP, volatility, maximum win potential, bonus mechanics and provider quality. These technical details are combined with practical session notes such as tested budget, number of spins, average stake, bonus activation frequency, dry streaks, biggest win multiplier and mobile stability.
He does not present short slot tests as proof of long-term performance. RTP is treated as a long-term mathematical indicator, while the practical test explains how the game behaved during a specific session.
Responsible gambling approach
Daan treats gambling as adult entertainment, not as a way to earn income. His reviews avoid promises of winnings, unrealistic expectations or aggressive promotional language.
For the Dutch market, he pays attention to responsible gambling signals, 18+ messaging, risk communication, player protection information and the relevance of the KSA and Cruks context. These factors are considered especially when reviewing safety, transparency and trust.
Editorial method
Daan follows a structured review checklist. For casino pages, this includes registration, KYC, deposit, withdrawal, bonus terms, live chat and mobile usability. For slot pages, this includes RTP, volatility, bonus features, gameplay rhythm, mobile stability and provider background.
His reviews include both positive findings and practical friction points. Examples include unclear bonus restrictions, slow support replies, dense mobile pages, missing payment details, long withdrawal review stages or limited filtering options in the game lobby.
Editorial independence
Daan’s reviews are based on defined criteria, practical testing and editorial analysis. Commercial relationships do not determine the final rating. If a page contains affiliate links, the same scoring logic still applies.
The aim of his work is to help readers understand how a casino or slot behaves in practice, where the main limitations are, and which details should be checked before playing.

Review limitations
Casino and slot reviews are based on structured checks and practical testing, but results can change over time. Payment speed may vary depending on the method, verification status and operator review. Slot behaviour can also differ strongly between sessions because short-term outcomes are random.
For this reason, Daan’s reviews focus on practical observations, transparency, risk awareness and clear methodology rather than guaranteed outcomes.
