Rainbet Affiliate Code RAKEBACK100 attaches a 250% deposit bonus up to $2,100, 60 free spins spread across your first three deposits, and a 20% rakeback boost covering your first 72 hours of play. Most people who enter it will do so on a phone rather than a desktop, and small screens introduce their own set of problems: collapsed registration forms, aggressive autofill, keyboards that capitalise things you did not ask them to capitalise, and sessions that drop when you switch apps to fetch a deposit address. This article is about that specific journey — getting the code into the right field, on a phone, before you fund the account.
Why the mobile path matters more than it sounds
The code cannot be applied retroactively. If you complete registration without it and then deposit, the package is not attached, and the rakeback boost — the part of the offer that pays as cash with no rollover — is simply not there. On a desktop, a registration form is usually visible in full, so a blank code field is hard to miss. On a phone the same form is stacked vertically, the optional fields are frequently folded behind a link, and the keyboard covers the lower third of the screen while you type. The single most common way to lose a welcome package is not a rejected code. It is a code that was never entered because the field was below the fold.
App versus mobile browser
Before deciding where to register, check the official site for what it actually offers on your device. Casino platforms in this space differ: some ship a downloadable application, some run entirely as a website that behaves like an app when saved to your home screen, and some do both depending on the operating system. Do not take a download link from a search result, a messaging app or a social post — if an application exists, the official site is the only place to confirm it.
For the narrow purpose of attaching a code, the mobile browser is usually the safer choice, for reasons that apply to registration flows generally:
The browser address bar lets you confirm you are on the official domain before you type anything. Inside a wrapped application, that confirmation is hidden from you.
Browser forms expose all optional fields reliably, and you can zoom, scroll and inspect what you have typed.
A browser session survives being backgrounded more predictably than some applications, which matters when you leave to copy a deposit address.
If something goes wrong mid-registration, a browser page can be reloaded without losing your place as often as a reinstalled app would.
Whichever route you take, the field you are looking for is the same one. Rainbet uses a single input at registration for affiliate, referral and promo codes — there is no separate box per code type, so if you have found one such field you have found the right one.
Where the field hides on a small screen
Registration forms on phones tend to follow a pattern. Email and password sit at the top, age and terms checkboxes sit at the bottom, and anything considered optional is compressed between them or hidden behind an expander. Look for these patterns before you press the button that creates the account:
A greyed link reading something like "Have a code?", "Add a promo code" or "Referral code (optional)" that must be tapped to reveal the input.
A collapsed section marked with a chevron or plus sign directly above the terms checkbox.
A second registration step that appears after the first, where the code field lives alone on its own screen.
A field already pre-filled with a code if you arrived through a link — check the contents rather than assuming they are correct.
If you scroll to the bottom and see no field at all, do not create the account and hope to add the code later. Close the page, reopen the official site fresh, and work through the form again slowly with the keyboard dismissed between fields so you can see the whole layout.
Typing RAKEBACK100 on a phone keyboard
Mobile keyboards are the main cause of codes that look correct and are not. Codes are normally case-insensitive and whitespace-sensitive, but you should not gamble on either. A few habits remove the risk entirely:
Type the code manually rather than pasting it, or paste and then inspect it character by character. Clipboard managers on phones routinely add a trailing space or a newline.
Watch for autocorrect converting the string into a suggested word, and for predictive text inserting a space after it when you tap the next field.
Check the digits at the end survived. Switching to the numeric keyboard mid-word is where characters usually go missing.
Dismiss the keyboard and read the field back at full size before submitting. Placeholder text and typed text look similar at small sizes on dim screens.
If the form rejects the entry, retype it from scratch instead of editing the existing text, which can leave invisible characters behind.
Confirm the package before you deposit
On a phone it is tempting to move straight from registration to the cashier, because the deposit button is usually the largest thing on the screen. Resist that. Once the account exists, find the bonus or promotions area of your profile and confirm the welcome package is showing as attached. This is the last point at which a mistake is cheap to fix. If it has not attached, contact support before any money moves, because a deposit made without the package cannot be retrofitted with one.
Also confirm that Rainbet operates in your jurisdiction. Around fourteen regions are excluded, among them the United States, the United Kingdom, Australia, the Netherlands and France, while Brazil and Canada are actively served. A phone on a mobile network can present a different apparent location than the same phone on home wi-fi, so check the terms rather than inferring eligibility from whether the site loaded.
Mobile-only quirks around the deposit and the 72-hour window
The rakeback boost runs for your first 72 hours of play, so the clock is a factor in how you sequence things on a phone. Two mobile behaviours deserve attention. First, app-switching: funding a crypto deposit usually means leaving the site to open a wallet, copy an address, and come back. Some sessions expire while backgrounded, so verify you are still logged in and on the correct deposit screen when you return, rather than pasting into a page that has quietly reset. Second, connection changes: moving between wi-fi and mobile data mid-transaction can interrupt a page load at exactly the wrong moment. Complete the deposit on a stable connection and give the confirmation screen time to appear before navigating away.
Deposit within the qualifying minimum and the per-deposit cap. If you are offered a choice between the wager-locked 250% track and a no-wager alternative, that decision is easier to make properly on a screen where you can read both sets of terms side by side, so consider reading the terms on a larger display even if you register on the phone.
Reading the terms on a small screen
Terms pages are where mobile reading genuinely disadvantages you, and this package has conditions worth understanding. The deposit bonus carries a 40x wagering requirement: a $700 bonus needs $28,000 in qualifying wagers, and the full $2,100 needs $84,000. While clearing it you cannot play Hacksaw Gaming or Nolimit City titles, nor anything with an RTP above 97.4%, and stakes are capped at 2% of your deposit. The 60 free spins carry their own rollover and expiry, listed separately from the deposit bonus, so read that section on its own terms.
The rakeback half behaves differently: it is a share of the house edge returned as cash, with no rollover attached. It is the smaller and less eye-catching component, and it is the one with real, withdrawable value.
A short mobile checklist
Confirm eligibility in your region before registering.
Register through the official site in a browser where you can see the address bar.
Expand every optional section on the form before submitting.
Enter RAKEBACK100 in the single affiliate, referral or promo code field.
Read the entry back with the keyboard closed.
Confirm the package is attached in your account before depositing.
Deposit on a stable connection, then start playing while the 72-hour rakeback window is live.
Rainbet is operated by RBGAMING N.V. under an Anjouan licence. That is not equivalent to a UK, Malta or Ontario licence, and it means your escalation path if a withdrawal is refused runs through the operator and then a licensing body with limited enforcement capacity — a point worth weighing on any device. Crypto withdrawals are typically processed within a day and fiat takes longer, so if you are managing everything from a phone, plan the withdrawal method at the same time you plan the deposit.
Gambling involves risk and is intended for adults aged 18 or over (or the legal age in your jurisdiction). Bonuses carry wagering requirements — read them in full before opting in, never stake more than you can afford to lose, and seek support if gambling stops being entertainment.
Promotional terms, eligibility and values are set by the provider and can change at any time. Always confirm the current terms on the official site before signing up or completing a purchase.
