What are the best strategies for playing blackjack at online casinos?

Memorize the basic strategy charts and stick to them like a dog with a bone. It doesn’t cost anything, is simple to apply and will bring the house edge below 1%. Don’t take any of the other (sure-to-be-losing) side bets offered. If you find 8-deck games with a 3:2 payoff for blackjacks, grab them by the horns. Double on 11’s, split aces, never take insurance and always stand on 17. Know that strategy varies among games; “European no hole card” blackjacks require a slightly different approach, which will put the house edge anywhere from 0.5% to 2%. Also, beware: if you’re on a roll, don’t try to press your luck. Random number generators have no memory.

Adhere strictly to basic strategy – this is the most fundamental requirement for successful blackjack. Memorize the basics, but use charts if you must. Don’t place side bets, which significantly increase the house advantage. Watch for 6:5 payouts on bets and no doubling after splitting pairs, and avoid casinos with these rules. S17 is preferable to H17 and fewer decks are better than more as well. Look for European or Atlantic City rule variations. Keep a clear head and never try to win back your losses. Play rationally, and stick around.
