The king of casino table games, blackjack offers one of the lowest house edges when played with basic strategy. Over 150 variants exist worldwide, but the core mechanic remains the same: beat the dealer by getting closer to 21 without busting. With optimal play, the house edge can drop below 0.5%.
Always use basic strategy. Gut feelings cost money over time.
Never take insurance unless you are counting cards and know the count is very high.
Look for tables that pay 3:2 for blackjack, not 6:5.
Prefer single or double deck games with favorable rules (dealer stands on soft 17, double after split allowed, late surrender).
Set a loss limit and a win goal before each session. Walk away when you hit either.
