Learn the rules and practise choosing when to hit, stand, double, split or surrender. Basic strategy improves decisions over many hands; it does not guarantee a profit.
Get closer to 21 than the dealer without going over. Number cards keep their value, faces count as 10, and an ace counts as 1 or 11. You play against the dealer, not the other players.
A + 7 = soft 18. Add a 9 and your ace becomes 1: now you have hard 17.
Hit takes another card. Stand keeps your total. Double adds an equal bet and gives exactly one more card. Split turns a matching pair into separate hands with separate bets. Late surrender returns half your original bet (rounded down here) after the dealer checks for blackjack.
Double and split need enough bankroll. Surrender is available on your original two-card hand.
Basic strategy combines your hand with the dealer’s visible card. A dealer 4, 5 or 6 is vulnerable, but a bust is never guaranteed. Against a strong upcard you often need to improve your hand.
Hard 12 stands against 4–6, but hits against 2 or 3. Small details matter.
A soft hand contains an ace still worth 11. That cushion creates good doubling opportunities. Pairs have their own strategy: splitting aces and eights is a useful starting point; keeping tens together protects a strong 20.
This trainer allows up to four split hands. Split aces receive one card each and cannot be hit, doubled or re-split. A split hand reaching 21 advances automatically. Split 21 is not a natural blackjack and pays 1:1 on a win.
A correct decision can lose and a poor decision can win. Basic strategy aims to improve the average result over many hands; it cannot promise a profit. Treat the chips as practice and judge your choices, not your last result.
Insurance is a separate bet on dealer blackjack. The trainer’s basic strategy declines it.
