iGaming Maths & Provably-Fair Analyst · Manchester, UK
“I read the maths behind the reels so players don’t have to gamble blind.”
I break down RTP, volatility and provably-fair systems into plain English — evidence over hype, on every page I publish.

About me
I'm Eleanor — an online-casino analyst based in Manchester. While a lot of reviews stop at the welcome offer and a screenshot, I work from the engine room: I model Return-to-Player figures, profile volatility and hit frequency, and calculate the true expected cost of a wagering requirement before anyone claims a single spin.
My signature specialism is provably-fair verification. On crypto casinos I walk readers through the whole proof chain — server seed, client seed and nonce hashed with SHA-256 — and show, step by step, how to confirm a result wasn't tampered with. It's a technical corner of the industry that few authors bother with, and it's where I've built my reputation.
I pair that quantitative side with a firm line on safer gambling. Every guide I publish points back to UK Gambling Commission standards, deposit-limit tools, affordability checks and self-exclusion through GAMSTOP. To my mind, transparency is a form of player protection — not a footnote.
When I recommend a game or a casino, you can be sure it survived a spreadsheet first.
What I do
A data-first toolkit for reading online-casino products honestly — the maths, the fairness proofs and the player-protection framework behind them.
Deconstructing theoretical vs. actual return across slots, table games and live formats.
Classifying games by risk, hit frequency and how long a bankroll realistically lasts.
Verifying seed/hash mechanics on crypto casinos — client seed, server seed, nonce, SHA-256.
The real value of a welcome offer once wagering requirements are costed out properly.
Game-show formats, side-bet edges and how those payout structures actually stack up.
Deposit and withdrawal flows, on-chain settlement and the KYC friction points that slow payouts.
UKGC framework, deposit limits, self-exclusion via GAMSTOP and affordability checks.
UKGC and MGA licensing signals that tell you whether an operator can actually be trusted.
How I review
Every verdict I publish follows the same documented process. Sessions are logged, sample sizes are stated, and RTP figures are sourced from provider maths sheets — not guessed at.
Before anything else, I check the UKGC operating licence, fund segregation and GAMSTOP integration. No licence, no review — I don't cover unlicensed operators.
I source published RTP and volatility data straight from the game providers, then note the theoretical house edge for each title I'm assessing.
I record spins, stakes and outcomes across a stated sample size so hit frequency and variance claims are backed by numbers you can see.
On provably-fair games I reproduce the SHA-256 hash from the server seed, client seed and nonce, and confirm the outcome matches the published proof.
I turn wagering requirements into real-money terms — game weightings, expiry and excluded titles included — so the offer's true value is clear.
I state any affiliate relationship openly, flag the safer-gambling tools on offer, and give a balanced verdict with the downsides left in.
