Sam Okafor is RainyBet's games and provably fair analyst, covering game mechanics, house edge and verification across the five crypto casinos the site reviews.
Beat
Sam's coverage is about how a game actually works underneath its interface: what its house edge is as commonly implemented, how a provably fair system commits to and reveals a result, and how a player can check that a specific round wasn't tampered with. This beat is deliberately separate from bonus terms — a game's mechanics and edge don't change because a promotion is attached to it.
He also builds and documents RainyBet's simulators, which reproduce published game mechanics so readers can watch variance and house edge play out over volume without risking real funds.
What he covers
- Individual game guides — mechanics, typical edge and how to read the multiplier or paytable
- Provably fair verification — server seed, client seed, nonce, and how to check a round yourself
- House edge explainers, including how edge interacts with turnover and rakeback
- RainyBet's simulators, built to reproduce published mechanics without real-money risk
- Beginner-facing "what is X" guides that introduce a platform's games before its bonus terms
Editorial standards
Sam states a house edge or RTP figure only where it reflects how a game family is commonly implemented across the industry, or where an operator has published the exact figure for a specific title — the two are never presented as the same thing. Provably fair explanations describe what a verification system actually proves, and are equally explicit about what it does not prove: verification confirms a round wasn't altered after the bet, not that the game carries a low edge and not that a player will win.

Licence, geo-restrictions and playing safely
Licensing. Access is blocked in a number of countries and US states, and the list is maintained by the operator rather than published as a stable document. The current restricted list and licence details live on the operator’s own terms page — read them before you register.
Your side of it. Crypto casinos settle fast, which is exactly what makes them easy to overplay. Before your first deposit at these operators, set a deposit cap and a session timer in the account settings — not in your head.
- Deposit limits and self-exclusion tools live in account settings, not support chat
- A losing session is not a signal to raise the stake — it is a signal to stop
- Bonus turnover targets are not a reason to keep playing past your limit
