Set the rules below. The calculator reads the published house edge for the table that matches.

Where these figures come from
Every figure on this page carries one of four labels. The label is the evidence behind the number, not a rating of it.
| Sourced | A named source published this figure for exactly this rule set. We transcribed it and we cite it. |
|---|---|
| Modelled | We computed this figure here, from a rule set we assembled. No other publisher states it. |
| Modelled and independently checked | We computed this figure here, and a published figure agrees with it inside the tolerance the rule set declares. |
| n.a. | Nobody published this figure and we did not estimate one. The page says n.a. and stops. |
Where these figures come from
Every house edge figure is read from a published source. The source URL is recorded next to the figure. Every strategy chart on this site is solved from the rules stated next to it. The solver runs here and the cells are not copied. The two are checked against each other. Where they disagree by more than the recorded solver error the page publishes our own number. The page marks that cell. Nothing on this page is computed in the browser.
The convention is basic strategy with a reshuffle after every hand. A land based table dealing to a cut card is priced elsewhere.
One rule set in the list below returns a player edge rather than a house edge. It is selectable in this calculator and in the trainer only. It has no page of its own and it is never attached to a casino.

Common questions
- Does this calculator compute a house edge?
- No. It matches the rules you set against a published table and reads the sourced figure for that table.
- Why do some combinations of rules return no figure?
- No table on this site deals that exact set of rules. No figure is estimated, so no figure is shown.
- Which shuffle convention do these figures use?
- Basic strategy with a reshuffle after every hand. A land based table that deals to a cut card is priced elsewhere.
- Can the calculator include side bets?
- No. Every figure here is for the main bet. A side bet carries its own house edge and is not added to this figure.
