What this is: the complete set of
house edges computed on this site, in one ranked table, with the exact
rational value beside each decimal. It is published as
JSON and
CSV under CC-BY, so it can be recomputed
and reused rather than taken on trust.
The cheapest twenty
Every one of these costs less than one per cent of what you stake. Note how few games appear: the bottom of this list is not a spread across the floor, it is a handful of bets inside three games.

The most expensive twenty
And the other end. The gap between the two tables is the entire argument for reading a figure before placing a bet: the same evening's money, at the same table in some cases, costing two orders of magnitude more.

What the ranking shows
- The spread within a game beats the spread between games. Craps holds bets at both ends of this list. Choosing craps over roulette decides far less than choosing which craps bet to make.
- The bets that pay most are priced worst. It holds across sic bo, Big Six and the proposition bets, and it is the single most reliable pattern here.
- Side bets are where the cost hides. A cheap main game with an expensive side bet is a more expensive table than an ordinary one, and the side bet is the part that gets advertised.
- One game is missing on purpose. Slots carries no row, because the reel weightings that would produce one are not published by anyone. A ranked list that includes slot machines is quoting, not computing.
How to use it
The JSON and CSV are the useful artefacts. Each row carries the game, the bet, the decimal, the exact fraction where one exists, and the URL of the page that derives it, so a claim can be traced rather than believed. The licence is CC-BY: reuse it, and link the page the figure comes from.
If you find a figure here you believe is wrong, that is the most useful message this site can receive. Every value is produced by software that can be re-run, and a correction goes into the engine rather than the page. Say which bet and which number.
