What this Blackjack calculator does

Basic Strategy Explorer. Pick your hand and the dealer's up-card and see the basic-strategy move for that hand.
The Measured Return. Re-runs a simulation of hands in your browser on every visit and shows the return it measures.
Bankroll Simulator. Set a starting bankroll and a session length and see how a session at that size is expected to go.

The figures on this page are computed in your browser from the constants the Blackjack game plays with, not typed in by hand. Flickloot is free play: coins are granted, never sold, and cannot be redeemed for anything.

NOT KNOWABLE FROM THE OUTSIDE

Blackjack's edge is set by the rule set, so a single number would be meaningless.

This build: dealer stands on all 17s · blackjack pays 3:2 · double on any two cards · no splits.
Change one of those and the figure moves. 6:5 blackjack alone costs the player more than a full point.
We publish what THIS rule set returns, measured. We will not quote the blackjack edge, because there is no such thing.
A real table's figure follows from its posted rules. Read them, then derive it the way we derived roulette.

No unsourced real-casino figure appears anywhere in this section. Where an edge follows from the rules it is derived and shown; where it does not, it is left out and the reason given.
