Current Bonuses at 21bit Casino

The headline offer for new players is a 100% match bonus up to 1 BTC plus 50 free spins on selected slot games. The wagering requirement is x30 on the bonus amount, which is below the industry average of x35-x40 for crypto casinos.

[!NOTE] The 1 BTC cap is the maximum bonus value. If you deposit less, the bonus scales proportionally. For example, a 0.1 BTC deposit yields a 0.1 BTC bonus.

How to Claim the Welcome Bonus

1. Register an account - Complete the sign-up form with your email and chosen password.
2. Make your first deposit - Select Bitcoin, Ethereum, Litecoin, Dogecoin, Tether, or Ripple. The minimum deposit to qualify is 0.0005 BTC.
3. Opt in automatically - The bonus is credited immediately upon deposit. No bonus code is required.
4. Use free spins - The 50 free spins are added to your account within 10 minutes of the deposit clearing.
5. Meet wagering - Play through the bonus amount 30 times before requesting a withdrawal.

[!TIP] Test the free spins on low-volatility slots first. This gives you a longer play session and a better chance of meeting the wagering requirement without burning through your balance.

Beyond the welcome offer, 21bit Casino runs a weekly schedule of reload bonuses and cashback. These are available to all existing players.

Weekly Reload Bonus

Every week, players can claim a 50% match bonus up to 0.5 BTC on their next deposit. The wagering requirement remains x30. This offer resets every Monday at 00:00 UTC.

• Availability: One claim per week per account.
• Eligibility: Minimum deposit of 0.001 BTC.
• Expiry: Bonus funds expire 7 days after being credited.

Free Spin Fridays

Each Friday, 21bit Casino awards 20 free spins on a rotating selection of slots. No deposit is required to claim the spins, but you must have made at least one deposit in the previous 7 days.

• Wagering on winnings: x30 on any winnings from free spins.
• Max withdrawal from free spins: 0.01 BTC.
• Game restriction: Spins are valid only on the slot featured that week.

Cashback Offer

Players receive up to 10% cashback on net losses over a 7-day period. The cashback percentage depends on your VIP tier:

Cashback is credited every Monday as bonus funds with a x10 wagering requirement. No opt-in is needed.

[!RISK] Cashback is not free money. It still requires wagering before withdrawal. If you are chasing losses, take a break. Contact Gambling Help Online AU on 1800 858 858 if gambling stops being fun.

The x30 wagering requirement applies to the bonus amount only, not the deposit plus bonus. This is a player-friendly structure compared to casinos that apply wagering to the total deposit+bonus.

Example: You deposit 0.1 BTC and receive a 0.1 BTC bonus. You must wager 0.1 BTC x 30 = 3 BTC before withdrawing any winnings derived from the bonus.

Game contribution to wagering:

• Slots (most titles): 100%
• Table games (blackjack, roulette, baccarat): 10%
• Live dealer games: 5%
• Video poker: 5%
• Jackpot slots: 0%

[!NOTE] If you play blackjack or roulette while wagering a bonus, only 10% of your bets count toward the requirement. Stick to slots to clear the wagering fastest.

During active wagering, the maximum bet per spin or hand is 0.001 BTC. Exceeding this limit voids the bonus and any winnings.

Games excluded from bonus wagering:

• Progressive jackpot slots
• Certain high-RTP slots (check the full list in the terms)
• All live dealer games (except where noted)

To qualify for any bonus, you must deposit using one of the supported cryptocurrencies:

• Bitcoin (BTC)
• Ethereum (ETH)
• Litecoin (LTC)
• Dogecoin (DOGE)
• Tether (USDT)
• Ripple (XRP)

Fiat methods (credit cards, bank transfers) are not currently supported for bonus qualification. This is a crypto-only bonus system.

• One bonus per household/IP address. Multiple accounts claiming the same bonus will be flagged and voided.
• Withdrawal restrictions. While a bonus is active, you cannot withdraw any funds until the wagering requirement is met.
• Expiry. Welcome bonus funds expire 30 days after being credited. Free spins expire 7 days after being credited.
• Max conversion. The maximum amount you can withdraw from bonus winnings is 10x the bonus amount. For a 0.1 BTC bonus, the cap is 1 BTC.

The x30 wagering and the 1 BTC cap put 21bit Casino above average for crypto-focused operators. The cashback structure is competitive, especially at higher VIP tiers.

21bit Casino offers a straightforward bonus system with below-average wagering requirements and a crypto-first approach. The welcome package gives new players a solid starting balance, and the weekly reloads and cashback provide ongoing value for regular players. The main limitation is the crypto-only deposit requirement, which excludes players who prefer fiat methods. If you are comfortable using Bitcoin or other cryptocurrencies, the bonus terms are among the better ones available to Australian players.
