Free online blackjack games give users the chance to play against a virtual dealer without committing any real money to the cause. While it's rare to find an online casino that will let you do this for long, it is common to find places that offer trial memberships. If, after a few days of playing for free, you decide that the game's not for you, there's no obligation whatsoever.
To sweeten the kitty, as they say in certain gambling circles, many of these same casinos induce spectators to become players through the promise of free gambling funds. An extra couple of hundred dollars can be all it takes to earn your business. This is even easier for an online casino if you've fared well in your trial run, which many people do--and there's a reason for this.
The Principle Behind Free Online Blackjack Games
The idea behind free online blackjack games--or any game of chance, for that matter--is that the house always wins over the long run. For this to happen, only one criterion need apply: the house must have at least a slight advantage. Even if you're the shrewdest blackjack player this side of the Mojave Desert, if you adhere precisely to the "basic strategy," the house still comes out with a very slight edge. This is just plain statistical sense.
If you flip a coin two times, the odds are pretty good that it will come up heads or tails both times. Up the trials to ten, and it's likely that you'll spend an entire day flipping that exact same coin and still not arrive at ten straight heads or tails. Multiply that by hundreds and hundreds of trials, and the chances of this happening go from minute to nil. Playing one or two hands is akin to flipping that coin twice; you have a pretty decent shot of coming out ahead. Stay in the game for the long haul, and you'll never win, even if you do manage some short-term successes.
