Blackjack is the rare casino game where correct play shrinks a large leak. These pages teach rules and charts. They do not remove the leftover house edge.

How to play blackjack: the deal, the buttons, the leftover edge
How to play blackjack is a short loop: you stake, you receive two cards, you see one dealer card, you hit stand double split or surrender, then the dealer finishes by a posted rule. Closer to 21 without busting wins even money; a two-card 21 usually pays 3:2. A matching chart shrinks leak. It does not create plus-EV. PVPspinArena does not deal blackjack.
Rules
Blackjack rules: S17, H17, 3:2 versus 6:5, DAS and surrender
Blackjack rules that move the edge: S17 versus H17, 3:2 versus 6:5, DAS, surrender, peek, and why a chart cannot repair a bad felt.
How many decks in blackjack: why shoe size moves the leftover edge
How many decks in blackjack: single versus two, four, six, eight and infinite-deck RNG, how shoe size moves leftover edge and a few chart cells.
Decisions
Blackjack chart: how to read the grid and what leftover edge remains
What a blackjack chart is, how to read rows and up-cards, a few key cells, leftover house edge, and why the grid shrinks leak instead of creating plus-EV.
Blackjack simulator: what EV and ruin numbers actually mean
What a blackjack simulator computes: EV, ruin, sample paths, how to read output, and why this site has no shoe simulator.
When to double down in blackjack: hard totals, soft totals, leftover cost
When to double down in blackjack: hard 9–11, soft 13–18, DAS, rule captions that move cells, and why extra stake is leftover-edge math — not plus-EV.
When to split in blackjack: aces, eights, and the pairs you should not
When to split in blackjack: always aces and eights, never tens, how DAS moves 2s 3s 6s 7s, and why a second stake shrinks leak instead of creating plus-EV.
What is insurance in blackjack: a 2-to-1 side bet that usually loses
What is insurance in blackjack: the 2-to-1 side bet on a ten in the hole, why even money is the same leak, and when a chart says no.
