About Tomasz Wiśniewski

The same slot can be released at several RTP settings, with 96%, 94% and lower versions of one game, and the casino chooses which to run. Tomasz Wiśniewski’s game pages start from that fact. Each RTP figure he gives is tied to its source: the studio’s published versions, or the information screen of the game as a given casino offers it. If neither can be confirmed, the page says the setting is unknown and leaves the figure out.

Most of his work is explaining what those numbers do and don’t mean. A 96% RTP describes the average over millions of spins. It doesn’t describe the €500 a reader brings to one evening, and his articles say so with the arithmetic in the sentence. He also covers volatility, house edge in blackjack and roulette variants, live dealer table rules, and the platform providers and white-label companies that sit behind many casino brands. Those companies explain why two sites can share a game library and a set of terms.

He has a master’s degree in mathematics from the University of Wrocław. He has lived in Ireland since 2011 and has written about casino games since 2013.

He doesn’t publish strategies for beating slots, because none exists, and he doesn’t use the word “due” except to explain why it’s wrong.
