This page is a count, not a review: which screen Bond spends the most time gambling in, and at which games. It is kept because the question is asked constantly and answered badly everywhere — usually by naming a single famous scene and stopping there.
Two things are worth saying before the list. The games in the films are not the games in a casino lobby: screen baccarat and screen poker are shot for tension, with hands dealt for the plot rather than from a shoe. And a film gambling scene is a costume drama about odds, not a demonstration of them. If you want the arithmetic instead of the cinema, the Slot Math section is where it lives, and the table games are described in Table Games.
How the count is done matters more than the answer, because the answer changes with the method. A scene is counted here only when Bond is actually staking money at a game with rules — sitting at the table, holding the cards, calling the bet — and not when a casino is simply the room a conversation happens in. A cutaway to a wheel, a walk past the pit, a drink at the bar of a gaming floor: none of that is play. Counted the strict way the list stays short and the order is stable; counted loosely, every film shot anywhere near a casino joins the tally and the question stops meaning anything.
The second reason the usual answers disagree is that the films change the games themselves. A screenwriter needs a hand the audience can read in seconds, so the rules bend: a table game is played faster than any floor would allow, cards arrive in an order no shoe would produce, and the decision is handed to the hero rather than to the odds. That is not a complaint about the films — it is the reason a gambling scene should never be read as a guide to a game. The rules as a casino actually deals them are in Table Games, and what a house edge does to a bankroll over a session is in Slot Math.
