Harriet Lowell

Writes about the arithmetic of casino games: what an hour of play costs, what a bonus costs to clear, and why the same slot can ship in several RTP versions.

Harriet Lowell worked with product data before she started writing about gambling, which is why her pieces tend to end in a number rather than an adjective. She covers slot mechanics, live table rules and the way game design shapes how long a session lasts. Her rule on this site is simple: if a figure cannot be checked by the reader, it does not go on the page.

What she checks before publishing

Every percentage on her pages is either standard game arithmetic — the house edge of European roulette, the cost of a 6:5 blackjack table, the expected loss on a given turnover — or a figure an operator has published itself, quoted with the date it was read. She does not use player statistics that cannot be sourced, and she does not quote experts who cannot be looked up.
