Bitcoin and crypto casino games
The bitcoin casino games here are made in-house and all play from one casino balance. These crypto casino games fix each result before you bet and show their RTP and current maximum win. Most settle in one draw, Mines and Chicken pay step by step, and every game has an Auto mode with stop-on-profit and stop-on-loss.
Crash and Limbo: multiplier games
In Crash, a shared multiplier climbs from 1x and busts at a point fixed before the round; you win by cashing out first, by hand or with auto cash-out. Crash has a theoretical RTP of 95%. Limbo pays when one drawn result meets your target multiplier, with a theoretical RTP of 97%.
Mines and Chicken: cash out step by step
Mines hides 1 to 24 mines, a count you choose, among 25 tiles; each gem raises the multiplier and a mine loses the stake. Chicken crosses 20 lanes, and Easy, Medium, Hard and Expert add cars and raise the pay per lane. Mines and Chicken each have a theoretical RTP of 97%.
Dice and Plinko: choose your risk
Dice rolls on a scale of ten thousand outcomes, and the lower the win chance you pick, over or under, the higher the multiplier. Plinko drops a ball through 8 to 16 rows, and Low, Medium or High risk sets how wide its payouts spread. Dice and Plinko each have a theoretical RTP of 97%.
Roulette and Reels
Roulette is a European single-zero wheel with 37 pockets for straight, split, dozen, column and red or black bets, at a theoretical RTP of about 97.3%. Reels spins three reels on five fixed lines with a wild, and a losing spin can trigger up to 12 respins that stop at the first line that pays; Reels has a theoretical RTP of about 96.5%.
No-KYC crypto casino: no ID to sign up
OVERDOG is a no KYC crypto casino: you sign in with Telegram or Google and upload no identity documents to open an account, deposit, play or withdraw. Withdrawals from the wallet are confirmed with 2FA, and each sign-in method opens its own account.
If you want a crypto casino no KYC so withdrawals never stall on an ID request, the check winnings meet here is about results: payouts wait for a fairness re-check of your settled rounds, not an identity check.
Bitcoin casino deposits
As a bitcoin online casino, OVERDOG takes BTC on the Bitcoin network and credits it as pUSD, a balance pegged one-to-one to the US dollar, so it stops moving with the BTC price. Casinos that accept bitcoin differ in where coins land; here it is your wallet, and you move only your stake money into your casino balance.
- Open Deposit and choose BTC.
- Select the Bitcoin network and copy the address shown.
- Send BTC to that address from your wallet or exchange.
- Wait for the dollar balance to appear in your wallet.
- Move the amount you want to play with into your casino balance.

How to deposit bitcoin
Bitcoin is the slowest supported network, so a BTC deposit takes longer than other routes; the deposit sheet shows an estimate and the live minimum for each. Check asset, network and address before sending: a transfer on the wrong network or to the wrong address cannot be recovered.
Deposit ETH, SOL, USDT, USDC or BNB
ETH deposits on Ethereum, Arbitrum, Base or Optimism, SOL on Solana and BNB on BNB Smart Chain. USDT runs on Arbitrum, Base, Optimism, BNB Smart Chain, Ethereum and Tron, never on Solana or Polygon, while USDC covers Polygon, Arbitrum, Base, Optimism, BNB Smart Chain, Ethereum and Solana. Layer twos, BNB Smart Chain, Solana and Tron are quickest.
Bitcoin casino withdrawals and payouts
A bitcoin casino withdrawal takes two moves, because your wallet and your casino balance are separate. You request a move from the casino balance back to your wallet at any time, then withdraw in BTC, ETH, SOL, BNB, USDT or USDC on the networks you can deposit on, with the minimum and network cost shown before you confirm with 2FA.
Each move back has two parts. Your own money, what you moved in minus what you took out, is returned outside the winnings queue, subject to the checks shown in the product. Winnings are paid up to a daily ceiling shared by all players and sized to the house's funds; winnings that do not fit wait in a queue and are released in turn as the ceiling frees up.
Before the first payout after play on a seed pair, you rotate that pair to reveal its server seed, and this applies whenever your active pair holds settled bets. Winnings then wait until a fairness re-check has re-derived every settled bet, which checks results, not identity. A move above a transfer limit is refused, not cut down, and a payout can pause for operator review.
Provably fair bitcoin casino games
As a provably fair bitcoin casino, OVERDOG commits to each result before you bet: the server publishes a hash of its seed, and the outcome comes from that server seed, your client seed and a nonce. Crash uses a pre-committed chain of round hashes plus a salt fixed before play.
Provably fair casinos let you check the work: rotate your seed pair to reveal the old server seed, then verify any round by matching it to its hash and recomputing the result. A match proves the calculation, not that a bet was accepted or paid.
Casino RTP and house edge by game
Every game shows its RTP, the theoretical share of stakes it pays back over many rounds. Dice, Limbo, Mines, Plinko and Chicken each have a theoretical RTP of 97%; Roulette sits at about 97.3%, Reels at about 96.5% and Crash at 95%.
The house edge is what remains: Dice, Limbo, Mines, Plinko and Chicken keep a house edge of 3%, Roulette an edge of about 2.7%, Reels an edge of about 3.5% and Crash an edge of 5%. Single-zero Roulette therefore leads the lowest house edge casino games here, followed by Dice, Limbo, Mines, Plinko and Chicken.
Even the casino games with the best odds keep an edge, so the house wins over time by design. RTP is a long-run average, not a forecast: a session can end above or below it, and no betting system changes the edge.
