Why rules matter: Published estimates can span 0–16.67%. The relevant number depends on the exact rules, wager, pay table, and strategy—not merely the game name.
What changes the math
- Pass and don't pass are among the stronger base bets.
- Odds bets have no house edge but require a line bet first.
- Proposition bets usually trade excitement for a high price.
A practical approach
Start with a line bet, learn odds, and ignore the center-table noise. A house-edge figure is useful only when it describes the actual rules and wager in front of you.
What house edge really means
House edge does not predict what percentage of your bankroll you will lose in one visit. It describes the casino’s expected share of total action over a very large sample. Short-term results can sit far above or below that average.
