About bsbj.win
A free blackjack trainer and set of guides. No downloads, no sign-up, no casino money behind it.
What this is
bsbj.win teaches blackjack the way it’s actually learned: read the rule, then drill it until it’s automatic. The trainer deals basic strategy hands and grades every move, plays out a full six-deck shoe with other players and a bankroll, and drills card counting. The guides explain the why.
Everything is free. Your progress is saved in your own browser and never sent to us (see Privacy).
How we check the facts
- The strategy is tested. The trainer’s answer key is code, and every update is tested against a separately written copy of the basic strategy chart for the same rules (6 decks, dealer stands on soft 17, double after split, no surrender). The charts on these pages are generated from that same answer key, so the guide and the trainer can’t disagree.
- Numbers come from named sources. House edges for side bets and game variants are from the Wizard of Odds. The Hi-Lo count plays are the Illustrious 18 from Don Schlesinger’s Blackjack Attack; KO is from Olaf Vancura and Ken Fuchs’s Knock-Out Blackjack; Zen is from Arnold Snyder’s Blackbelt in Blackjack.
- Casino listings name their source and date. Each region on Where to play says where its rules came from and when. Rules change, so check the felt before you sit down.
- Player reports are labeled. Reports from players are marked “Unverified” and are never used as a source for the listings themselves.
- When we don’t know, we don’t say. A number we can’t source doesn’t go on the page.
Who pays for it
No casino pays us, and no listing is paid placement: there are no affiliate links on this site. If the site ever shows ads, they’ll be clearly marked and never placed in the middle of a hand.
Playing responsibly
This site is for practice and entertainment. No strategy guarantees a win, and even perfect play loses money over a short session more often than not. Read Play responsibly before you bet real money.
