Game Rules
Game rules, bonus guide & how playthrough works
Blackjack
Objective
Beat the dealer by getting a hand value closer to 21 without going over. If your hand exceeds 21, you "bust" and lose immediately.
Game Setup
We use a 6-deck shoe (312 cards) with provably fair shuffling. The deck is shuffled fresh for each hand using cryptographic randomness that you can verify.
Card Values
Game Flow
Player Actions
Draw another card. You can hit multiple times until you stand or bust.
Keep your current hand and end your turn. The dealer then plays.
Double your bet on any two cards, receive exactly one more card, then automatically stand.
If you have a pair, split into two hands. Requires a matching bet for the second hand.
Payouts
Important: Blackjack vs. 21
Key Distinction
Blackjack (Natural) is specifically an Ace plus a 10-value card (10, J, Q, K) dealt as your first two cards. This pays 3:2.
21 with 3+ cards is just "21" — it beats hands under 21 but only pays 1:1, and loses to a dealer's natural blackjack.
Soft vs. Hard Hands
Soft Hand
Contains an Ace counted as 11. Example: A-6 = "Soft 17". You can hit without risk of busting (the Ace becomes 1 if needed).
Hard Hand
No flexible Ace. Example: 10-7 = "Hard 17". Hitting risks busting if you draw a 5 or higher.
Splitting Rules
- You may split any pair (two cards of the same rank)
- Cards must match by rank, not just value (K-K can split, K-Q cannot)
- Split up to 3 times (maximum 4 hands)
- Doubling after split is allowed
Special Rule: Split Aces
When you split Aces, each hand receives only one card. You cannot hit, stand, double, or re-split after splitting Aces. This is standard casino rules.
If you split Aces and receive another Ace, you cannot split again — you play that hand with the cards dealt.
Insurance
When the dealer's face-up card is an Ace, you may take insurance before play continues:
- Insurance costs half your original bet
- Pays 2:1 if the dealer has blackjack
- After your insurance decision, the dealer peeks at their hole card
- If dealer has blackjack, the hand resolves immediately (insurance pays if taken)
- If dealer doesn't have blackjack, you lose the insurance bet and play continues normally
Tip: Statistically, insurance is not a favorable bet in the long run.
Dealer Rules
- Dealer must hit on 16 or less
- Dealer hits on soft 17 (Ace + 6 = dealer draws again)
- If dealer busts, all remaining player hands win
Not Offered
Surrender is not available. Some casinos allow you to forfeit half your bet against a dealer showing 10 or Ace, but we do not offer this option.

How to Play
Our slot machine uses a simple spin-and-win system. Each spin generates a random outcome from the prize table below. The reels display symbols that represent your result.
Wager Options
Choose from preset wager amounts: 1, 10, 100, 1,000, 2,000, 3,000, or 5,000 sats. Your selected wager is deducted when you spin. Winnings are calculated as the multiplier times your wager.
Prize Table
Each spin results in one of these outcomes. Your payout is your wager multiplied by the multiplier shown.
| Outcome | Symbols | Multiplier |
|---|---|---|
| Jackpot | 7️⃣ 7️⃣ 7️⃣ | 20x |
| Triple Diamond | 💎 💎 💎 | 10x |
| Triple Lightning | ⚡ ⚡ ⚡ | 8x |
| Triple Bitcoin | ₿ ₿ ₿ | 5x |
| Triple Fruit | 🍒 🍒 🍒 | 3x |
| Any Pair | 🍒 🍒 🍊 | 2x |
| Small Win | 🍒 🍒 ⚡ | 1x |
| Miss | 🍒 💎 ⚡ | 0x |
Example
If you wager 1,000 sats and hit Triple Bitcoin (5x), you win 5,000 sats. Your net profit is 4,000 sats (5,000 won minus 1,000 wagered).
Roulette
Overview
European single-zero roulette. A ball is spun on a wheel with 37 pockets (0-36). Place bets on where the ball will land. The single zero gives a house edge of 2.7%.
How to Play
Inside Bets
| Bet Type | Description | Payout |
|---|---|---|
| Straight | Single number (e.g., 17) | 35:1 |
| Split | Two adjacent numbers | 17:1 |
| Street | Row of three numbers | 11:1 |
| Corner | Four numbers in a square | 8:1 |
| Line | Two adjacent rows (6 numbers) | 5:1 |
Outside Bets
| Bet Type | Covers | Payout |
|---|---|---|
| Dozen | 1-12, 13-24, or 25-36 | 2:1 |
| Column | 12 numbers in a column | 2:1 |
| Red / Black | 18 numbers of that color | 1:1 |
| Odd / Even | 18 odd or even numbers | 1:1 |
| Low / High | 1-18 or 19-36 | 1:1 |
The Zero
Green Zero (0)
The zero is neither red nor black, neither odd nor even, and not part of low (1-18) or high (19-36). When the ball lands on zero, all outside bets lose. You can bet on zero directly as a straight bet at 35:1.
Multiple Bets
You can place multiple bets on a single spin. For example, bet on red and on number 17 at the same time. Each bet is settled independently. Your total bet is the sum of all chips on the table.

Understanding Your Bonus Balance
Your account has two balances that are tracked separately:
Cash Balance
Deposited sats and unlocked bonuses. Withdraw anytime (min 100 sats).
Bonus Balance
Sats from bonuses that still need playthrough. Play to unlock, then they move to your cash balance.
- Your total balance (shown in the header) is cash + bonus combined — you can play with all of it
- Only the cash portion is available for withdrawal until playthrough is complete
- Different bonuses have different playthrough rates: free spin and daily streak are 1x, deposit bonus is 5x, referral bonuses are 1x
- Deposit match and referral bonuses must be manually claimed from the "Unclaimed Rewards" card in the casino lobby. You must have a verified email to claim. Unclaimed bonuses expire after 30 days
- Bonus sats are wagered first. If your bonus is consumed before playthrough completes, cash wagers still count toward the requirement — keep playing to unlock
- When you try to withdraw, you'll see how many more sats you need to wager if a bonus is still locked
