The mathematics of the house
Belmond is an independent publication about how gambling actually works — the published odds, the rules as they are written, and the history behind them. We sell nothing, take no wagers and promote no operator.
Every bet on a casino floor has a published price. It is expressed as a percentage of turnover, it ranges from half a percent to sixteen, and almost nobody checks it before sitting down.

Return to player is the most quoted number in the industry and the least useful one on its own. Volatility is the number that describes what an evening actually feels like.

Red has come up eight times. The ninth spin has not noticed, does not care, and is priced exactly as the first one was.

No autoplay, no turbo, no celebrating a loss as a win, a minimum 2.5 seconds a spin and a hard cap on the stake. Britain now legislates slot design itself.

Three riffles is not a shuffled deck. The number that is has been known since 1992, and it is more than most dealers do.

Two players with the same edge and the same bankroll can have wildly different odds of still being solvent in a year. The difference is how much they put on each hand.

The arithmetic under every wager: house edge, expected value, the margin built into a price, and what bet size does to a bankroll over time.
Blackjack, baccarat, craps and roulette — the rules as they are actually dealt, and the published cost of every bet on the layout.
How a reel game decides an outcome, what a return-to-player figure does and does not promise, and the rules Britain now imposes on slot design.
Pot odds, outs and hand frequencies — the parts of poker that are arithmetic rather than opinion.
All 2 in PokerWhere the 52-card deck came from, how the suits settled into their modern form, and what mathematicians found when they finally studied the shuffle.
