More from your account
Ongoing offers for account holders
By the time the welcome code is spent, these three keep the account going.
65STARREFILL — 65% up to A$290
Sixty-five per cent match up to A$290 on a Friday top-up, claimed with 65STARREFILL at the cashier from A$30, closed after seven days.
15GOLDCOVER — 15% cashback
Fifteen per cent of weekly losses back up to A$2,000, requested in the profile with 15GOLDCOVER, carrying a wager of 3 times on the cashback itself.
Code-free VIP boost
Twenty per cent extra reaches chosen accounts without any code, tied to a wager of 5 times, and the invitation arrives through the account inbox.
At the moment the code fails
From refused to accepted in one step
Madnix Casino names the reason first, then the small correction that unlocks the offer.
Check which players the code is built for
A code tagged for newcomers will not open on an account that already exists, and a reload code needs a first deposit behind it. Log in with the matching account type.
The full match you came for
Every offer sets its own floor, from A$7 on the welcome deal up to A$200 on the high roller code. Top up to the stated figure and paste the code once more.
Madnix Casino app code field
The app has no code box on the deposit screen in some builds, so the field simply is not shown. Finish that step in the mobile browser, then reopen the app.
Has the entry window closed?
Each offer carries its own entry window, and a code past that window is closed for good. Load the cashier list and pick a code still open to you.
A verified path to the bonus
Withdrawals and bonus release wait until identity, address and card images are on file. Send the three documents, then the code opens after review.
A traced record for you
Nothing left to try means the cause sits on the casino side. Write to support with the code and the time of the deposit, and the record settles it.
Knowing the cost
The figures behind every code
On the evening you pick a code, these four lines decide the real cost.
130START — 130% up to A$800 + 155 free spins
130START needs at least A$7 paid in, gives 130 per cent up to A$800 plus 155 spins, and wagers the bonus 29 times within 46 days.
With 50SUPERSPINS you get 50 spins worth A$0.10 each on Book of Dead at registration, and the part players miss is the A$100 cap on anything you withdraw from them. → Spins

Keeping the bonus
Madnix Casino limits that cancel a code
This block settles why a code dies and when it earns its keep.
Madnix Casino codes go first
Entering the code after the payment misses the cashier field entirely, so no bonus lands on the deposit and the amount stays plain cash.
Type the code in the cashier first
Pay in only after the field accepts it
Watch the stake cap
A stake above the maximum bet of A$4 during play voids 130START, because the wagering rules treat oversized bets as a breach of the offer.
Keep every stake at A$4 or less
Recheck the cap on highroller codes
Avoid the barred wallets
Skrill and Neteller are excluded payment methods here, so a deposit made with either one carries no bonus even when the code was typed correctly.
Pay by Visa, PayID or POLi instead
Read the excluded methods before paying
Claiming without slips
From registration to cleared wager
On the first attempt, this order stops the code from missing its slot.
Madnix Casino single account
Open an account with an email address and one password; the casino allows a single account per person, so any duplicate is closed without warning.
Before the field, no spaces
Paste the code with no spaces into the code field at the point the offer names, whether that is registration, the cashier or the profile.
First payment moment
Pay in at least the minimum the code states, A$7 for 130START and A$30 for the reload, using a method that is not excluded.
Is the bonus there yet?
Check the balance for the bonus or the spins before touching a game; if nothing shows, stop and ask support rather than playing on.
Finish before the deadline
Clear the wagering inside the stated days, and pace the play across the window rather than chasing it in the final evening.
Set your ceiling before the spins run
Once a code is active, nothing on the page obliges you to keep spinning. Set deposit limits, a loss ceiling, session reminders or a full self-exclusion from your profile, and reach Gambling Help Online, Lifeline Australia or the National Self-Exclusion Register for support.
deposit limits. A cap on what you can pay in over a day, week or month, applied before the next deposit.
self-exclusion. A block on your account for a chosen stretch, closing deposits and play until it ends.
loss limits. A chosen maximum loss or a nudge when time is up, so one session stays one session.
Madnix Casino example
From A$20 deposited to a balance you must turn over
The welcome code applies once, at the first deposit, and everything after it comes from the reload, cashback and high roller lines. The worked example turns the bonus into turnover and estimates what it costs at 96% return to player.

Straight answers on codes
Entered already, or not yet
Ten minutes here and the code side of your account is clear.
trustWhy can't I add a bonus code once my account is made?+
Because some codes need the account to start with them. The 50SUPERSPINS no-deposit code belongs in the registration form, not the cashier. Codes such as 130START or 65STARREFILL sit on the deposit screen instead, so entering them later at the cashier works.
trustDo I need to tell the casino when I skip a bonus?+
Not at all. Offers are optional, and a deposit made without a code simply lands as cash with no wagering attached. Should a code activate by mistake, stop before you wager and ask live chat to remove the bonus from the balance.
trustDo I need to wager winnings on every code here?+
Yes, each one carries a requirement. The lightest sits on 15GOLDCOVER at 3x the cashback, the heaviest on 50SUPERSPINS at 40x the winnings from its spins. Read the figure before you paste, because none of these five codes arrives without one.
trustDo I need to pay in to claim the no-deposit spins?+
No. Register with 50SUPERSPINS and 50 spins on Book of Dead appear at 0.10 each. Winnings carry 40x wagering over five days, bets stay at A$2 or below, and the cashout ceiling is A$100 after verification.
trustCan I stack a welcome code and a reload code together?+
Only one offer rides on a single deposit, so enter 130START or 65STARREFILL, never both at once. Space them apart: the welcome deal covers your first payment, and the Friday reload waits for a later one.
trustWhy does the regulator's name matter to me?+
Because it decides who hears a complaint. Madnix Casino N.V. holds licence OGL/2007/5664/856 from the Gaming Control Board Curaçao, and that board oversees the terms behind every code on this page.
trustCan I enter a code from my phone instead of a computer?+
Often, yes, since the cashier loads in the mobile browser as it does on a desktop. Some app builds hide the code field, so if it is missing, finish the deposit step in your browser and the bonus attaches normally.
