for card counters it definitely is, especially when it comes to single-deck blackjack. with a house edge around just 0.15%, it's beatable if you know the game well and can ride out variance.
i would never gamble on chance-based games. i love poker, and i'm all about playing in games where i have an edge.
Does a single-deck blackjack exist somewhere? As far as I know, 4 to 8 decks are usually used.
there are obviously way less single-deck games now than there used to be. you can still find several casinos in vegas (and elsewhere) offering them though, just not on the strip.
i'm not too familiar with the online casino scene these days, but i know playtech, microgaming, and rival gaming software all include single-deck variants. it's just a matter of whether specific casino skins offer them. my understanding is that when you find single-deck games, the odds are usually switched from the classic 3:2 to 6:5 to offset the easier games.
Even if you somewhere find a place where they play one deck, then mixing is done when about 30% of the deck is used, so there is no way to make calculations and get an advantage due to this.
i disagree. face up cards = dead cards which cannot be dealt from the deck again.
if single-deck gives card counters no edge, why did casinos switch to multi-deck? why do single-deck games pay with worse odds?
