How this crypto blackjack table plays
Our Blackjack is built in-house and returns 99.43%, the highest RTP of any game we make ourselves. It's you against the dealer. You bet, take two cards, see one of the dealer's, and then hit, stand, double or split while the dealer plays out a hand by fixed rules. Every bet and every payout settles in crypto.
Here's the whole rulebook. It's short, and it's why the number is so high:
Blackjack pays 3:2. Win normally and you're paid even money. Tie the dealer and your bet comes back to you.
The dealer stands on every 17. Soft 17 too. They keep drawing up to 16, then stop.
The dealer peeks. Show a ten or an ace and they check for blackjack before you've made a move, so you never lose a double or a split to a dealer natural.
Double on any first two cards. Your stake doubles and you take one card, no more.
Split any pair, once. The cards only need the same value, so a jack and a king count as a pair. Each new hand carries your original stake, and you can double on it. Split aces get a single card apiece, and a 21 made after a split pays as a normal 21, not as blackjack.
Insurance pays 2:1. You're offered it for half your bet whenever the dealer shows an ace.
What 99.43% RTP costs you
RTP is what a game pays back over a very long run of bets. Out of every $100 you put through our table, the house expects to keep 57 cents. Scale that to $1,000 and it's $5.70. That's the 0.57% edge written as money. Every published blackjack RTP assumes perfect decisions, ours included, which is why the strategy section further down is worth a minute.
Some context. Most of our other in-house games run at 98%, which is $2 per $100. A single-zero roulette wheel keeps $2.70. A blackjack table that pays 6:5 on a natural instead of 3:2 costs roughly $1.90. Our table games ranking lines all of these up side by side.
The edge is charged per bet, so pace matters too. A hundred $10 hands in an hour works out to an expected cost of about $5.70. Faster play doesn't change the percentage, it just puts more money through it.
An infinite shoe, and why it matters
Most blackjack deals from a shoe of six or eight decks. Ours draws every card from a full 52-card deck, fresh each time. Nothing gets used up, and that changes a few things:
There's nothing to count. Counting works by tracking what's left in a shoe. Here, nothing is ever left out.
The odds of each card never move. A ten-value card is always 4 in 13, about 30.8%, and an ace is always 1 in 13.
A natural lands 4.73% of the time, roughly once every 21 hands, and pays you 1.5 times your bet when it does.
It also settles the insurance question. With an ace showing, the hole card is a ten 4 times in 13. Paying 2:1 on that leaves insurance with a house edge of about 7.7%, more than thirteen times what the main game costs. Turn it down, even when you're holding blackjack yourself.
Six plays that keep you close to 99.43%
You don't need a full chart to get most of the way there. These six cover the hands people get wrong most often:
Always stand on hard 17 or more.
A dealer showing 2 to 6 busts more often than one showing anything else, so let them. Stand on hard 13 to 16, and on 12 when they show 4, 5 or 6. Against a 2 or 3, hit a 12.
When the dealer shows 7 or more, don't stop on hard 12 to 16. Keep drawing.
Double a hard 11 against any dealer card from 2 to 10. Double a hard 10 against 2 to 9.
Split aces and eights. Never split tens or fives.
Skip insurance.
Our bitcoin blackjack guide goes further into the maths, including why a 6:5 table costs nearly four times as much as a 3:2 one.
Provably fair blackjack: check any hand yourself
Every card on our table comes from three inputs: a server seed we commit to before you play, a client seed you can change whenever you like, and a nonce that goes up by one with each bet. Before you play, you only ever see the server seed as a hash. Swap the seed after the fact and the hash wouldn't match, which is the whole point.
Checking a hand takes a couple of minutes:
Note your client seed and the nonce for the hand you want to check.
Rotate your seed pair, which reveals the old server seed in full.
Open the verify page, pick Blackjack and paste in the client seed, nonce and server seed.
The tool deals out the dealer's cards, your cards and the order every card after them would have come in. It should match your hand exactly.
The provably fair overview explains the hashing behind it, if you want to rebuild a result without our tool at all.
Play with Bitcoin, USDT or 12 other coins
Bets are shown in dollars and settle in the coin you hold. We take 14: Bitcoin, Ethereum, Litecoin, USDT, USDC, XRP, Tron, Toncoin, Solana, BNB, Polygon, Dogecoin, Bitcoin Cash and Cardano. If you'd rather your balance didn't drift with the market between hands, keep it in USDT or USDC.
New players also get a deposit bonus across their first deposits. Read the wagering terms before you bring bonus money to a blackjack table, because they decide how far it goes.
Our table or a live dealer?
Ours deals as fast as you click, and you can check every hand. A live table moves at the dealer's pace, with real cards on camera and other players around you. Both have their place. The blackjack section had 357 games when we counted on 6 October, many of them live dealer tables, each with its RTP on the tile.
Whichever you pick, look at two things before you sit down: what a natural pays and what the dealer does on soft 17. A 3:2 payout and a dealer who stands get you most of the way to a good game.
Other in-house games you can verify
If checkable maths is what you're after, Video Poker pays back 99%, and our single-zero Roulette returns 97.3%. Dice, Crash, Mines and the rest of the in-house games mostly sit at 98%, and every result on them can be checked the same way.
