Inês Carvalho - Slots and Game Mechanics Expert

Biography

I have analysed online slots for seven years. I began my professional career at Playtech, where I worked for two years as a casino game tester. My responsibilities included checking paytables, RTP, volatility levels, betting limits and the operation of bonus rounds. I also tested each title on desktop, tablet and mobile to identify differences in performance, loading and interface adaptation.

For the following five years, I worked at Pragmatic Play as a product specialist in the slots division. I followed new releases from the testing stage through to their launch on platforms, compared different mathematical models and analysed features such as free spins, multipliers, special symbols, jackpots and bonus buy systems. I also prepared technical evaluations for content and product teams.

During this period, I tested more than 900 slots and published 260 complete reviews. I also developed my own framework with 25 criteria, used to evaluate RTP, volatility, feature frequency, rule clarity, maximum potential, betting limits, visual quality, technical stability and performance on mobile devices.

My preferred providers are Play’n GO, Pragmatic Play, NetEnt, Hacksaw Gaming and Nolimit City. My favourite titles include Mental and Fire in the Hole 2 by Nolimit City, due to their combination of multiple features, multipliers and high volatility. I also highlight Reactoonz for its chain reactions, Big Bass Bonanza for its collection system during the bonus round and Wanted Dead or a Wild for the variety of its special modes.

Before evaluating a slot, I consult the paytable, check the technical data and test the base game and bonus features separately. I also analyse how volatility affects the frequency and size of wins. My goal is to explain clearly how RTP, mechanics and the level of risk influence the experience of each game.
