You have checked the code twice, pasted it carefully, and still the cashier rejects it. Before you blame the casino, look at what is actually sitting in the promo-code box. Browser autofill has a habit of quietly dropping saved text into any field it thinks looks familiar, and a promo-code input is exactly the kind of box it misreads. The fix is simple: disable autofill for the cashier page specifically before you deposit.
Why autofill targets the promo-code field
Browsers learn from every form you fill. Once you have saved a name, address, email, or username, the autofill engine builds a profile of what a “field” looks like and starts guessing. A promo-code input is usually a short single-line text box sitting near payment fields, which is close enough to a username or coupon box that the browser decides it knows what goes there. It fills the field before you have a chance to type, and it does so silently.
The result is that you paste WELCOME2026 into a box that already contains a fragment of your street address or your email prefix. Sometimes the paste overwrites the autofilled text, sometimes the autofill fires after your paste and wipes the code. Either way the field no longer holds the code the casino expects, and the deposit processes without the bonus attached. The welcome package at True Fortune Casino, which unlocks up to A$1,500 plus 200 free spins with WELCOME2026, is only as good as what actually reaches the server.
This is not a rare glitch. Anyone who has saved payment details in Chrome, Safari, Firefox, or Edge is exposed, and the more aggressive the browser’s form-filling settings, the more likely the overwrite. The field looks correct at a glance because it contains text, and that text is the problem.
How to stop the overwrite before you deposit
The reliable fix is to switch off autofill for the cashier page rather than for the whole browser. In Chrome, open Settings, then Autofill and passwords, then Payment methods and Addresses and more, and remove or pause the saved entries you do not want offered. You can also right-click the promo-code field, choose the autofill suggestion list, and clear the stored entries that keep appearing. In Firefox the equivalent lives under Privacy and Security, then Autofill. Safari users can turn off AutoFill for contact and credit card data in the browser preferences.
If you would rather not disturb your saved data, open the cashier in a private or incognito window. Private windows do not carry autofill profiles by default, so the promo-code box stays empty until you type into it. The trade-off is that you will need to enter payment details manually each time, which is a small price for a clean field.
Whichever route you take, verify the box before you hit deposit. Click into the promo-code field, select all, and retype WELCOME2026 by hand rather than pasting. Pasting from a clipboard is fine in principle, but the browser’s autofill can still fire on focus and replace the pasted value, so typing is the safer habit. WELCOME2026 must be entered during the deposit process, not after, so you get one clean shot at it.
What to check on the True Fortune cashier screen
True Fortune Casino is described as an offshore operator, and it does not publish wagering requirements for the welcome package or specify the minimum deposit for the package. That makes the cashier screen your main source of truth, and you can check https://true-fortune-online.com/bonus-codes/ for further details. Before you confirm, read the promo-code box character by character, confirm the amount matches what you intended, and check whether the site shows a confirmation that the code was accepted. If the field contains anything other than WELCOME2026, clear it and start again.
Other checkout mistakes that cost you the bonus
Autofill is the quiet one, but it is not the only way a valid code fails. A common error is entering the code in the wrong field. Some cashiers have a separate sign-up code, deposit code, and promotional code box, and only one of them is read at the point of deposit. If you are a new player making your first deposit, the deposit code field is the one that matters. Putting WELCOME2026 into a general comments box or a referral field does nothing.
A second mistake is depositing before the code is applied. The welcome package is tied to the first deposit, and once that deposit clears without a code, the bonus is usually gone. There is no second first deposit. If you are unsure whether the code took, contact support before you fund the account, not after. Keep a screenshot of the cashier screen showing the code and the amount, because offshore operators can be slow to resolve disputes and a timestamped image is worth more than a description.
A third mistake is assuming the bonus terms are visible. Because True Fortune Casino does not publish wagering requirements for the welcome package, you should ask support directly what the playthrough requirement is, which games count toward it, and what the maximum bet is while a bonus is active. The default promotion is a 200% match for pokies, so if you plan to play table games or live dealer titles, confirm they count at all. Games such as Balloon by SmartSoft, HelicopterX, Carnival Rush by Betsoft, and FootballX are worth checking against the eligible list before you deposit, since a bonus that cannot be cleared on your preferred game is not much of a bonus.
A fourth mistake is reusing a code you found on a forum without checking the current offer. Promo codes expire, and an old code entered into a cashier that has moved on will simply fail. The WELCOME2026 code is intended for new players making their first deposit, so existing customers should not expect it to apply. If you have deposited before, ask support for the current offer instead of forcing an old code.
Finally, watch for the browser remembering a failed attempt. If you entered a wrong code once, autofill may keep offering that wrong code every time you return to the cashier. Clear the saved entry or use a private window so the stale value does not resurface at the worst moment.
Before your next deposit at True Fortune Casino, do three things in order. Turn off autofill for the cashier page or open it in a private window, type WELCOME2026 by hand and read the field back to confirm it is exact, and screenshot the cashier screen before you confirm. If the code is rejected, stop, check the field contents, and contact support rather than depositing again.
