Using the website

Select the best available option and we'll tell you if you made the best choice.

Your streak and totals are shown below.

You can use the left and right arrow keys to change buttons and the Enter key to submit.

Never take insurance (betting the dealer has blackjack).

There are options available to display the estimated value and/or the relevant row of the strategy table after your choice every round.

You can also display your "chips" above, where you gain a chip for the right choice and lose one for the wrong choice. You can't go negative.

You can also choose which hands are generated, between hard, soft, and split, to quiz yourself where you need help.

This website assumes the following table rules:

• Blackjack pays 3:2
• Dealer stands on a soft 17
• Infinite size deck
• Double after a split allowed
• Split up to three times except aces
• Draw only one card per split ace

This website does not feature a surrender option, however if one is allowed, you should surender only on hard 16 against 9, 10, or ace, or hard 15 against 10.

Based on these rules, the player's expected value is -0.511734%.

However, this value can turn positive with a simple card counting scheme, such as hi-lo. Learning basic strategy is the first step to being a profitable blackjack player.
