Wersja 1.2 — Ostatnia aktualizacja: 2026-10-29. Operator: JOKR Labs.
Niniejsza strona stanowi część Warunków Świadczenia Usług. Zawiera ona dla każdej z sześciu gier, które operujemy na naszych własnych serwerach (tzw. „JOKR Originals"), pełne pisemne zasady. Te same zasady są wyświetlane w panelu ℹ️ wewnątrz każdej gry. Wersja angielska ma pierwszeństwo przed każdym tłumaczeniem.
Operator entity details will be published here upon completion of licensing.
1. Jak czytać te zasady
1.1. Każdy Original jest rozgrywany dokładnie według poniższych zasad (BlackJOKR, Crash i Mines są również weryfikowane poprzez symulację ponad 10 milionów gier na kodzie samej gry; JOKR Duel poprzez symulację 1 miliona meczów). Jeśli wynik zależy od sposobu gry (BlackJOKR, Crash, Mines), Pani/Pana wybory zmieniają wyniki.
1.2. W żadnym Original nie ma ukrytego mechanizmu: każda przewaga kasyna jest jedną z poniższych napisanych zasad. Pani/Pana rzeczywiste wyniki w trakcie sesji mogą znacznie różnić się od jakiejkolwiek średniej długoterminowej.
1.3. Rakeback jest wypłacany dodatkowo do wypłat samej gry. Na każdym Original oprócz JOKR Ballz zwraca 5 % do 15 % rake'u (3 % każdej stawki) w zależności od Pani/Pana poziomu JOKR i poziomu VIP, plus tymczasowe bonusy dodane do tej stawki; gdy bonus depozytowy jest aktywny, rakeback jest nadal naliczany według tej stawki, ale tymczasowe bonusy (booster) są wstrzymane (zobacz stronę Promocje). JOKR Ballz nie ma przewagi kasyna: jego stawki nie zarabiają rakeback i nie liczą się do poziomów VIP, skrzynek cashback ani tygodniowych i miesięcznych rankingów obstawiania.
2. BlackJOKR
- 6 decks, shuffled before every hand.
- The dealer draws to 16 and also draws on soft 17 (a 17 counting an ace as 11); the dealer stands on hard 17 and on 18 or more.
- Blackjack pays 1:1 (even money).
- Ties are a push: your stake is returned, blackjack against blackjack included.
- You may double only on a two-card total of 10 or 11 (one card is dealt). No double after a split.
- You may split a pair once, into 2 hands (no re-split); split aces receive one card each; 21 after a split is not a blackjack.
- No insurance, no surrender. The dealer does not check for blackjack: a dealer blackjack beats every hand, and you lose your whole stake, doubles and splits included.
- Side bets are settled on your first two cards (Perfect Pairs) and on those two cards plus the dealer’s face-up card (21+3), whatever happens in the main hand.
- Perfect Pairs: Perfect pair (same rank and suit) 25:1, Colored pair (same rank and colour) 12:1, Mixed pair (same rank, different colours) 6:1 — X:1 means you win X times your side bet and your stake is returned.
- 21+3: Suited trips 100:1, Straight flush 40:1, Three of a kind 30:1, Straight 10:1, Flush 5:1 — X:1 means you win X times your side bet and your stake is returned.
Rakeback is paid on top of the game's payouts: 5 % to 15 % of the rake (3 % of each bet) depending on your JOKR tier and VIP level, plus temporary boosts added on top of that rate (see the Promotions page); the boosts are paused while a deposit bonus is active.
3. JOKR Duel
- Three cards: Red beats Orange, Orange beats Blue, Blue beats Red.
- First to win 3 rounds wins the match. A round where both cards are the same does not count.
- Against the house, every house card is fixed before the match starts: it is derived from a secret seed (HMAC-SHA256 of the seed, the game id and the round number, each card with equal odds). The SHA-256 hash of the seed is shown before you play and the seed is revealed when the match ends, so you can check every house card.
- Against the house, the winner takes the pot (both stakes) minus a 20 % house fee: a win pays 1.6× your stake. Player-versus-player matches have no fee.
Rakeback is paid on top of the game's payouts: 5 % to 15 % of the rake (3 % of each bet) depending on your JOKR tier and VIP level, plus temporary boosts added on top of that rate (see the Promotions page); the boosts are paused while a deposit bonus is active.
4. JOKR Ballz
- Each ball costs $0.36; a match holds up to 100 balls.
- All balls race on the same track; the first ball through the finish wins the match for its owner.
- The winner receives the whole pot: every ball in the match × the ball price. The house takes nothing.
- House players (bots) may enter with more balls than you. Every ball has the same chance, so your odds are exactly your share of the balls.
- If no ball finishes within 3 minutes, the winner is drawn at random, weighted by number of balls.
Bets on this game earn no rakeback and do not count towards VIP levels, cashback chests or the weekly and monthly wagering leaderboards.
5. JOKR Spin
- European wheel: 37 pockets (0–36), single zero.
- Payouts: straight 35:1, split 17:1, street 11:1, corner 8:1, six line 5:1, dozens and columns 2:1, red/black, odd/even and 1–18/19–36 1:1. Zero loses every outside bet.
- Before each spin the SHA-256 hash of the server seed for that spin is shown. The pocket is HMAC-SHA256(seed) reduced to 0–36 without bias (equal odds), and the seed is revealed after the spin so you can recompute the result.
Rakeback is paid on top of the game's payouts: 5 % to 15 % of the rake (3 % of each bet) depending on your JOKR tier and VIP level, plus temporary boosts added on top of that rate (see the Promotions page); the boosts are paused while a deposit bonus is active.
6. JOKR Crash
- The multiplier rises from 1.00× until the round crashes. Cash out before the crash to win your stake × the multiplier at that moment; an auto cash-out pays exactly its target when the target is below the crash point.
- Crash point = floor(100 × 0.964 × 2^52 ÷ (2^52 − h)) ÷ 100, where h is the first 52 bits of HMAC-SHA256(seed, salt). It is never below 1.00× and is capped at 1,000×; the maximum win per round is $2,500 (max bet $120).
- The SHA-256 hash of seed + salt is published before betting opens; both values are revealed after the crash.
- The salt of every round played under these rules starts with “v2-”; rounds whose salt has no such prefix were played with 0.9 instead of 0.964 in the formula above.
Rakeback is paid on top of the game's payouts: 5 % to 15 % of the rake (3 % of each bet) depending on your JOKR tier and VIP level, plus temporary boosts added on top of that rate (see the Promotions page); the boosts are paused while a deposit bonus is active.
7. JOKR Mines
- 5×5 grid with 1 to 20 mines. Each safe tile raises the multiplier; cash out at any time.
- Multiplier after k safe tiles = 0.96 × fair odds, rounded down to 0.01 (fair odds = 1 ÷ probability of k safe picks).
- Maximum win $600 per game.
- The mine layout comes from an HMAC-SHA256 stream of a seed committed by its SHA-256 hash when the game starts; seed and salt are revealed when the game ends.
- The salt of every game played under these rules starts with “v2-”; games whose salt has no such prefix used 0.9 instead of 0.96 in the multiplier.
Rakeback is paid on top of the game's payouts: 5 % to 15 % of the rake (3 % of each bet) depending on your JOKR tier and VIP level, plus temporary boosts added on top of that rate (see the Promotions page); the boosts are paused while a deposit bonus is active.
