版本 1.2 — 最后更新：2026-10-29。 由 JOKR Labs 运营。

本页面是服务条款的一部分。它为我们在自己的服务器上运营的六款游戏（"JOKR Originals"）分别阐述了完整的书面规则。相同的规则也显示在每款游戏内的 ℹ️ 面板中。英文版本优先于任何翻译版本。

1. 如何理解这些规则

1.1. 每款 Original 都完全按照下面的规则进行（BlackJOKR、Crash 和 Mines 还通过在游戏自身代码上模拟超过 1000 万局游戏进行验证；JOKR Duel 通过模拟 100 万场比赛进行验证）。如果结果取决于你的玩法（BlackJOKR、Crash、Mines），你的选择会改变你的结果。

1.2. 任何 Original 中都没有隐藏机制：每项庄家优势都是下面书面规则中的一项。你在一个游戏局中的实际结果可能与任何长期平均值差异很大。

1.3. 返利金在游戏本身的派彩之外支付。除 JOKR Ballz 外，每款 Original 都根据你的 JOKR 等级和 VIP 等级返还 5 % 至 15 % 的抽水（每次投注的 3 %），加上在该费率基础上增加的临时加成；存款奖金活跃期间，返利按该费率继续发放，但临时加成（加速器）暂停（见促销页面）。JOKR Ballz 没有庄家优势：其投注不赚取返利，也不计入 VIP 等级、现金返利宝箱或每周和每月投注排行榜。

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.

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.

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.

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.

8. 记录和争议

8.1. 每手牌、每轮、每次旋转和每场比赛都在我们的服务器上记录，包括其投注、结果和支付，以及——对于承诺-揭示游戏（对阵庄家的 Duel、Spin、Crash、Mines）——承诺的哈希值和揭示的种子。

8.2. 如果你认为某款游戏未遵循这些规则，请通过 JOKR Support — 应用内支持聊天（任一主标签页脚的“联系支持”）或 support@jokr.casino 联系我们，并提供游戏名称和该轮的时间。我们将检查服务器记录并用记录的数值进行回复。
