Make decisions while you keep the count

Six decks, dealer stands on soft 17, blackjack pays 3:2, no surrender. You can double on any first two cards and split a pair once; split aces get one card each. Insurance is offered when the dealer shows an ace, and the shoe is reshuffled after about 75% of the cards are dealt. You start with 1,000 in play money and bet in units of 10.

Training mode shows the running and true count, the basic strategy play and any count-based deviation that applies. Exam mode hides all of it, so the count lives only in your head.

After every hand you type the running count before the next deal. The table tells you if you were exact and, if not, what the count really was. These checks feed the table accuracy on your progress page.

The deviations shown are a subset of the well-known Illustrious 18 index plays for Hi-Lo. With other systems they are only a rough guide. The bankroll is play money: winning here says nothing about results in a real casino.
