Reading the table: the last column is the expected cost of keeping that bet working for your whole session at your numbers. Not a prediction of any single night, the long-run average the casino builds its business on.

Free odds are missing from the list on purpose: they cost exactly 0.00% and can only back a line bet, which is why the strategy is always "smallest line bet, biggest odds".
What "resolves" means here
A line bet rides many rolls before it wins or loses; a proposition bet resolves every roll. The session-cost column accounts for that: each bet's cost is edge × bet × (rolls × resolution rate) × hours, using the share of rolls that settles each bet, from the dice: 11 in 36 for the 6 and 8, 10 in 36 for the 5 and 9, 9 in 36 for the 4 and 10, 165 in 557 for the line bets, every roll for the Field and the props. So an hour's cost does not follow the house edge: per roll, the hardways, the Big 6 and 8 and the field that pays 3 to 1 on the 12 all cost the same 1/36 of the bet, and at this page's default settings the 3-to-1 field (2.78%) costs more an hour than placing the 4 or 10 (6.67%). Fast-resolving bets turn a small edge into a large bill, which is exactly why the middle of the layout is where bankrolls go to die.
Frequently Asked Questions
- Why is the Field so much more expensive than Place 6?
- Two reasons multiply: its edge is higher (2.78% or 5.56% against 1.52%), and it resolves every single roll while a place bet waits for its number. Cost is edge times action, and the Field generates about three and a quarter times the action.
- Where are the free odds?
- At exactly 0.00% they are the best wager in the casino, but they only exist behind a line bet. Small line bet, maximum odds is the whole strategy.
- Are these numbers simulated?
- No. Every edge is an exact fraction derived from the 36 outcomes of two dice - 7/495 for the Pass Line - and verified against references before this page could build. The browser only multiplies by your numbers.
Corrected on 18 October 2026 (this note itself corrected on 19 October): the calculator used hand-typed settlement rates. They are now the dice's own, and each hourly cost moved with its rate: hard 4 and 10 from 0.45 a roll to 9 in 36 (about 44% cheaper), hard 6 and 8 from 0.35 to 11 in 36 (about 13% cheaper), place and Big 6 or 8 from 0.25 to 11 in 36 (about 22% dearer), place 5 or 9 from 0.25 to 10 in 36 (about 11% dearer), and the line bets from 0.30 to 165 in 557 (about 1% cheaper).
Corrected on 19 October 2026: the paragraph above said the ranking of the bets never changes; at the default settings the 3-to-1 field costs more an hour than placing the 4 or 10, although its house edge is lower.
Every edge behind this calculator is computed from the 36 outcomes of two dice in exact rational arithmetic and checked against published references at build time. The browser multiplies; it never derives.
