The rules this table deals
Rules decide the house edge, so hiding them is how a bad version of this game gets away with being bad. Here is exactly what is dealt:
- Eight decks, reshuffled after every hand
- Dealer stands on all 17s, including soft 17
- Blackjack pays 3 to 2, insurance would pay 2 to 1
- Double on any first two cards, including after a split
- Split up to four hands; split aces get one card each
- No surrender
Played correctly, that set of rules gives up about 0.5% to the house, which is close to the best bet in any casino. Play on instinct instead and it climbs past 2%. Leave the hints on until the right move is obvious.
21+3 side bet odds
Your two cards plus the dealer's upcard, scored as a three card poker hand. These chances are counted over every combination of an eight deck shoe, not copied from a marketing page.
| Hand | Pays | Roughly |
|---|---|---|
| Suited three of a kind | 100:1 | 1 in 4,091 |
| Straight flush | 40:1 | 1 in 485 |
| Three of a kind | 30:1 | 1 in 193 |
| Straight | 10:1 | 1 in 32 |
| Flush | 5:1 | 1 in 17 |
Something pays about 9.73% of the time, and the bet returns 96.3% over the long run, so the house keeps 3.7%.
Perfect Pairs side bet odds
Your first two cards only. A perfect pair is the same rank and the same suit, coloured is the same rank and colour, mixed is the same rank in different colours.
| Hand | Pays | Roughly |
|---|---|---|
| Perfect pair | 25:1 | 1 in 59 |
| Coloured pair | 12:1 | 1 in 52 |
| Mixed pair | 6:1 | 1 in 26 |
Some kind of pair lands about 7.47% of the time, and the bet returns 95.9%, so the house keeps 4.1%.
So should you take the side bets?
On the numbers, no. The main game gives up about 0.5% when you play it properly. The side bets give up 3.7% and 4.1%, which is seven to eight times worse, and no amount of timing or pattern watching changes that because every hand is dealt from a freshly shuffled shoe. They exist because a 100 to 1 hit feels good. Take them if that is what you are paying for, and put the chips you were going to lose on them somewhere you actually enjoy.
Blackjack FAQ
Is this blackjack simulator free?
Yes. It runs in your browser with no signup and no money. The chips are pretend, so you can practise a strategy for as long as you like without risking anything.
What rules does it use?
Eight decks reshuffled every hand, dealer stands on all 17s including soft 17, blackjack pays 3 to 2, double on any first two cards including after a split, split up to four hands, split aces draw one card each, and no surrender. That is the standard crypto casino setup.
What is the house edge in blackjack?
With these rules and correct basic strategy it is roughly 0.5%, which is one of the best in any casino. Play by hunch instead and it climbs past 2%, so the strategy is worth far more than any betting system.
Are the 21+3 and Perfect Pairs side bets worth it?
Not if you care about the maths. Enumerated over an eight deck shoe, 21+3 keeps 3.70% and Perfect Pairs keeps 4.10%. Both are seven to eight times worse than the main game. They are there for the swings, not the value.
What are the odds of a perfect pair?
About 1 in 59 hands on eight decks. A coloured pair is roughly 1 in 52 and a mixed pair 1 in 26, so some kind of pair shows up about 7.5% of the time.
Can card counting work here?
No, and not because we stop you. The shoe is reshuffled after every single hand, which is exactly what the crypto casinos do and exactly why counting does not beat them either.
