21bit Casino Promo Code Guide: How WEEKEND, TOP40 and TOP100 Work

Which 21bit Casino promo codes are available?

21bit Casino has three named promotional codes in its current offer set. Each one matches a particular reward and deposit condition. The code itself does not replace the deposit requirement, so have the qualifying amount ready before applying it.

Code	Reward	Deposit condition	Availability
WEEKEND	40% Weekend Reload bonus	Minimum deposit AU$20; maximum bonus AU$100	Saturday and Sunday; other markets
TOP40	40 free spins on a top slot	Deposit of at least AU$20	Other markets
TOP100	100 free spins on a top slot	Deposit of at least AU$40	Other markets

For Australian players, the cashier and promotion terms are the practical checkpoints before you deposit. The listed codes are marked for other markets, so do not assume a code will apply to an Australian account simply because the code appears in the promotion details.

How to apply a 21bit promo code

Applying a code is straightforward, but timing matters. The code needs to be attached to the qualifying deposit, and the deposit amount must meet the promotion’s stated threshold. A quick check before payment can save you from using the wrong offer.

Choose the promotionPick WEEKEND, TOP40 or TOP100, then read the reward and deposit condition beside it.
Open the cashierSign in to your 21bit Casino account and open the deposit area. The deposit button is in the top right on desktop and the bottom right on mobile.
Enter the codeAdd the exact code in the promotion or bonus field: WEEKEND, TOP40 or TOP100. Codes are best entered before confirming the deposit.
Meet the deposit conditionFor WEEKEND, the deposit minimum is AU$20 and the maximum bonus is AU$100. TOP40 requires at least AU$20, while TOP100 requires at least AU$40.
Check the rewardBefore playing, confirm that the account shows the intended match bonus or free-spin reward. If the promotion does not appear, avoid making another deposit just to test a different code.

The same basic approach applies whether you are on a phone, tablet or desktop. 21bit Casino has iOS and Android apps, and the casino is optimised for mobile devices and tablets.

WEEKEND code: the reload offer and its limits

The WEEKEND code is connected to a 40% Weekend Reload bonus. It has a minimum deposit of AU$20 and a maximum bonus amount of AU$100. The promotion is available on Saturday and Sunday in other markets.

Code	Match	Minimum deposit	Maximum bonus
WEEKEND	40%	AU$20	AU$100

A simple example shows how the percentage works. A AU$20 qualifying deposit would produce a 40% match of AU$8, while a AU$250 deposit would reach the AU$100 maximum rather than generating a larger bonus. The promotion terms still control whether the reward is credited and how it can be used.

Remember that WEEKEND is a time-based code. If you are considering it on a different day, check the promotion’s active period first. It is also separate from the Daily Spin Wheel, which turns once per 24 hours on a qualifying deposit and can award spins or a match bonus.

TOP40 and TOP100: free-spin codes for top slots

TOP40 and TOP100 are designed for free spins on a top slot. TOP40 gives 40 free spins when the deposit is at least AU$20. TOP100 gives 100 free spins when the deposit is at least AU$40.

Code	Free spins	Minimum deposit	Game reference
TOP40	40	AU$20	A top slot
TOP100	100	AU$40	A top slot

The two codes are easy to compare. A deposit of AU$20 meets the TOP40 threshold, while a deposit of AU$40 meets the TOP100 threshold. The promotion description refers to a top slot, so check the eligible game shown with the reward before starting the spins.

These offers are not the same as every other free-spin promotion at the casino. Other rewards include the Daily Surprise Spins, which are claimed the day after a deposit of at least AU$20, and Tuesday’s Book Club, where a Tuesday deposit lets the player choose a free-spin quantity. Those promotions use their own conditions rather than TOP40 or TOP100.

Bonus terms to check before using a code

A promo code is only one part of an offer. The wagering rule, expiry period, maximum bet and eligible games can affect how you use a reward. Reading those points first is worth the minute it takes - honestly, this is the part most people skip.

Check whether the reward is a match bonus or free spins.
Confirm the minimum deposit and any maximum bonus or cashout amount.
Look for the activation period and the time allowed to use the reward.
Keep the maximum bonus bet in mind: the general maximum while a bonus is active is AU$7.5.
Check the wagering multiplier. Cash bonuses other than loyalty-exchange bonus funds clear at 45x the bonus amount.
Remember that slots contribute 100% towards bonus wagering, while roulette, video poker, poker, craps and dice, other card games and table games contribute 0%.

For example, a AU$10 cash bonus with a 45x bonus wagering rule would require AU$450 in qualifying wagering. That calculation uses the bonus amount, not the deposit amount. Loyalty-exchange bonus funds use a separate 10x rule, but that is not the basis for the three promo codes discussed here.

Deposits and account checks that can affect a promotion

21bit Casino accepts AUD and other fiat currencies, along with cryptocurrencies including BTC, BCH, ETH, LTC, DOGE, USDT, XRP, ADA, TRX and BNB. Australian accounts can also use PayID and Osko. Deposit methods include Visa debit, Mastercard debit, bank transfer, Neosurf, PaysafeCard, Neteller, Skrill, Jetonbank, Rapid Transfer and MiFinity.

Fiat card deposit limits depend on the card method: one route accepts AU$15 to AU$4,000, while another accepts AU$20 to AU$6,000. Cryptocurrency deposits have their own minimums, and all crypto deposits are free of charge. Payment routes are checked every 4 hours.

Skrill and Neteller deposits do not qualify for the welcome package, so check the exact promotion before choosing either method. More generally, use an account in your own name and keep one account per individual. Accounts sharing a residential address, household, IP address or device are treated as duplicates.

Players must be at least 18 years old or meet the minimum legal age in their jurisdiction. Age verification can be requested. For Bitcoin players, a valid passport or driver’s licence is required before playing with BTC, with deposits and bets blocked until verification is complete.

Playing with a promotional balance

Once a code has been accepted, take a moment to identify the reward in your account. If it is a match bonus, separate the bonus amount from your cash deposit when working out the wagering requirement. If it is a free-spin reward, check which top slot is connected to the offer and use the spins within the stated period.

Use only games that contribute to the relevant wagering requirement.
Keep every bet at or below AU$7.5 while a bonus is active.
Track the bonus expiry date and any free-spin activation window.
Do not request a withdrawal before completing a package if its terms say that doing so closes remaining rewards.
Remember that gambling is entertainment with real financial risk. Set limits from your player profile if you want a firmer spending boundary.

The casino offers more than 3,000 games, including slots, fast-play titles, jackpot games, live casino, table games, video poker, Megaways and bonus-buy games. Demo mode is available, which can help you learn a game before deciding whether to use a promotional balance.

Support and responsible use of promotions

If a code or reward needs clarification, live chat and email support operate 24/7. Support is available in English, French, German, Finnish and Norwegian, and the average live-chat response time is 3 minutes.

You can set gambling limits from your player profile. Self-exclusion is also available by contacting support, who activate it with your written permission. Account closure requests must be sent by email with a reason; live-chat requests are not actioned.

21bit Casino Online also provides encrypted payments and certified random number generators independently verified by third-party institutions. Treat every promotion as optional entertainment, and only deposit an amount you can afford to lose.
