Select a chip, then click a betting spot to add it.
Each chip adds the same bet to both hands. Super Match, when selected, adds one more bet of the same amount.
Switch the second card of each hand?
Educational simulation: fun credits only, no real money. Six decks, dealer hits soft 17, blackjack pays even money, and a dealer 22 pushes every hand except a natural. This felt allows one split per hand; the Simulate tab plays the full rules including resplits to four hands.
You post two equal bets every round, so the edge below is measured against both. A $5 selection means $10 at risk per round before any double or split.
The simulator switches by comparing the exact expected value of both arrangements, which is a shade better than any human method and a shade worse than the published optimal figure (its strategy is derived under an infinite-deck approximation). Runs therefore settle slightly above 0.58%, and that is the model talking, not a leak: with the deck model equalised, the simulator and our exact solver agree to well inside one standard error. Dealer-22 is the sharpest check on the felt here, since it is fixed by the dealer's rules alone and cannot be moved by strategy. The switch rate counts every round dealt, including the ones a dealer blackjack ends before you get to choose.
What the free switch actually costs you
| The rule | In ordinary blackjack | In Switch |
|---|---|---|
| Blackjack pays | 3:2 (or 6:5 on bad tables) | Even money |
| Dealer draws to 22 | Dealer busts: you win | Push, unless you hold a natural |
| 21 made by switching | n/a | Counts as 21 points, not a blackjack |
| Swapping cards between hands | Impossible | Allowed, once, on the second cards |
Those first three are the price of the fourth. Push 22 is the heaviest of them: the dealer reaches exactly 22 on roughly 7.4% of resolved rounds, and every one of those is a hand you would have won outright at a normal table.
Super Match, on your four starting cards
| Hand | Pays | Chance | Odds |
|---|---|---|---|
| Four of a kind | 40:1 | 0.0357% | 1 in 2,804 |
| Two pair | 8:1 | 1.5342% | 1 in 65 |
| Three of a kind | 5:1 | 1.9567% | 1 in 51 |
| Pair | 1:1 | 35.2205% | 1 in 3 |
| No pair: loses | −1 | 61.25% | n/a |
A pair alone shows up on 35.2% of deals, which is why this bet feels like it pays constantly. It still costs 2.55%, because a pair only returns your stake, and the 61.3% of deals with nothing take it away.
How to decide the switch
The exact answer compares the expected value of both arrangements, which is what this simulator does. Humans use a published shortcut instead: Cindy Liu's point count: score each way of arranging the four cards and take the higher. The source publishes two versions: the advanced count costs about 0.08% against perfect play and the simpler one about 0.17%: a fair price either way for something you can do at the table.
The Play tab shows both arrangements' values on every hand, so you can watch which one the math prefers and why. The how-to page walks through the point count itself.
