Multiplayer Blackjack — 1v1 Duel Against a Friend (2026)

Blackjack Duel is multiplayer blackjack for two. You and a friend (or the bot) each play your own cards against one shared dealer, and whoever finishes further ahead of the dealer takes the hand. The first to win two hands takes the pot, less a 5% cut, so the winner collects 1.90× their stake. Nobody sees the other's cards until both of you are done, so there is nothing to copy.

How to play Blackjack Duel

1
Open Blackjack Duel in the Games hubLaunch Gift Club inside Telegram, open Games and pick Blackjack Duel from the PvP room.
2
Choose a stake and a rivalStakes are 10, 20, 50, 100 or 200 Stars, or a Gram (formerly Toncoin) stake from 0.1 to 10, and both players stake the same amount. Send a challenge link to a friend in any Telegram chat, which stays open for 10 minutes, or start straight away against the bot, which is labelled as a bot. The bot plays for Stars or Sparks, so a Gram duel is always against a friend. A Spark duel costs 1 Spark and pays XP instead of a pot.
3
Play your own handYou and your rival are dealt your own cards against the same dealer. Hit, stand, double or split as in the solo game, with 30 seconds for each move. Doubling and splitting cost nothing extra in a duel.
4
Wait for the revealYour rival's seat shows only two card backs, with no count and no status, until you have both finished. Then the dealer plays out once for both of you.
5
Win two handsWhoever finished further ahead of the dealer takes the hand. A tied hand is dealt again. The first to win 2 hands takes the pot: both stakes less a 5% cut, so 1.90× your own stake.

Blackjack Duel payouts

How a hand is scoredEach seat counts the net stakes it won against the dealer, and the higher count takes the hand. A split adds both of its hands together.

Your result against the dealer	Counts as
Win	+1
Blackjack	+1.5
Win after doubling	+2
Push	0
Loss	−1
Loss after doubling	−2

How the pot pays outBoth players stake the same amount in the same currency, and the pot is the two stakes combined, less a 5% cut. Every Stars tier is even, so the winner always collects whole Stars. A Gram pot is floored to the nanoton, and every Gram tier pays exactly 1.90×.

Your stake	Pot	Winner collects	Effective multiplier
10	20	19	1.90×

100	200	190	1.90×

Blackjack Duel pros and cons

Pros

Your own cards and one shared dealer: the same dealer hand for both of you, so luck is level
Your rival's seat stays sealed until you are both done, so there is nothing to read or copy
Doubles and splits cost nothing extra, so you play the strongest hand rather than the cheapest
First to two hands, so one bad hand doesn't decide the match
A challenge link for a friend, or a labelled bot when you want a match now
Accepts Gram as well as Stars, and every hand is provably fair

Cons

The 5% cut means the winner collects 1.90×, not the full 2× of the pot
Net stakes decide a hand, so a double or a split moves the score even though it costs nothing
Ties are common and replayed, so a match can run past three hands
A move clock: out of time on two hands in a row forfeits the match
Gram duels need a friend, because the bot plays only for Stars or Sparks

How does multiplayer blackjack work here?

In a casino, players share a table but each plays their own hand against the dealer, and nobody plays against each other. Blackjack Duel turns that into a head-to-head: you and your rival are dealt from the same shoe, each with your own cards, against one dealer hand. Whoever ends the hand further ahead of the dealer takes it. If you both finish the same distance ahead of the dealer, or the same distance behind, the hand is level and nobody scores.

The rules of each hand are those of the solo Blackjack game: six decks shuffled fresh for every hand, blackjack pays 3:2, the dealer hits soft 17, you double on a hard 9 to 11 and split once. The solo guide has the full rules table and the basic-strategy chart, and both apply to your hand here.

How is a hand decided?

By net stakes. A win counts +1, a blackjack +1.5, a doubled win +2, and losses count the same in the other direction, so the table above is the whole scoring system. Because a double and a split cost no extra stake in a duel but still move the score, they are about winning the hand rather than about money.

Hands are decided only when the two counts differ. Ties are common, and a tied hand is dealt again with a fresh shoe: nobody scores, nothing is refunded and the match carries on. The first to win two decided hands takes the pot.

Can my rival see my cards?

No. Your rival's seat appears as two sealed card backs, with no count, no status and no hint of timing, until you have both finished the hand. The dealer plays only after both seats are done, so the first player to finish never sees the dealer's final total, which would be the answer to the other seat's hand. Both seats then see the same dealer cards and each other's hands, and the score updates.

What does the 5% cut leave you?

Both stakes go into the pot, 5% goes to the house, and the winner collects 1.90× their own stake at every tier: 19 on a 10 duel and 380 on 200. Winning half of your decided duels returns 95% of what you staked, which is the margin a pot takes in every Gift Club duel.

What happens if you run out of time?

Each move has a 30-second clock. When it runs out your hand is stood for you and the match carries on, and your rival keeps playing. Run out of time on two hands in a row and you forfeit the match to your rival. If you both run out of time on two hands in a row, the match is abandoned and both stakes are refunded. A challenge link stays open for 10 minutes, and if nobody takes it the stake goes back to you.

Is Blackjack Duel provably fair?

Yes. The match commits to one server seed up front, shown as a hash, and reveals it when the match finishes. Every hand is a fresh six-deck shoe derived from that seed and the hand number: the creator's cards come off the front of the shoe, the rival's from a separate stretch behind the dealer's, and the dealer's off the back, so neither seat's cards depend on the other's moves. Once the seed is revealed the whole match replays from it. Against the bot, the cards are derived from the seed and the bot's own choices are not. Provably fair verification covers the check.

Which game should you play?

Want to learn the chart first: Blackjack, where Spark rounds show the best move for each hand.
Want a quick duel with a decision in every hand: this one. Compare it with PvP Dice Duel, where there is nothing to decide after the stake.
Want a duel that rewards skill over many turns: Sea Battle.

Blackjack Duel FAQ

How much does the winner get in Blackjack Duel?

The winner takes both stakes less a 5% cut, which is 1.90× their own stake at every tier: 19 on a 10 duel, 380 on 200, and 19 on 10.

How do you win a Blackjack Duel?

You and your rival each play your own cards against one shared dealer. Whoever wins more net stakes against the dealer takes the hand, and the first to win 2 hands takes the pot.

What happens on a tie in Blackjack Duel?

The hand is dealt again with a fresh shoe and nobody scores. Ties are common, so a match often runs past three hands.

Can my opponent see my cards or my moves?

No. Their seat shows two sealed card backs, with no count and no status, until you have both finished the hand. The dealer plays only after both seats are done.

Can I play blackjack with friends in Telegram?

Yes. Pick a stake, send the challenge link to a friend in any Telegram chat, and the duel starts when they open it. The link stays open for 10 minutes. If you want a match now, start one against the bot.

Can I play Blackjack Duel for Gram?

Yes, against a friend. Blackjack Duel accepts Gram stakes from 0.1 to 10 alongside the 10 to 200 Star tiers, and the winner takes the doubled pot less the 5% cut, floored to the nanoton. The bot plays only for Stars or Sparks, so a Gram duel starts with a challenge link.

What happens if a player runs out of time?

Each move has a 30-second clock. When it runs out your hand is stood for you, and running out of time on two hands in a row forfeits the match. If both players run out of time on two hands in a row, the match is abandoned and both stakes are refunded.
