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 for your first 72 hours of play. Most people who register do so on a phone, and a phone is exactly where a single-field code entry is easiest to miss. This article looks at the sign-up from a small screen: where the field sits, what changes between a mobile browser and a shortcut on your home screen, and the handful of mobile-specific habits that stop a package from failing to attach.
Why the mobile path deserves separate attention
On a desktop registration form, every field is usually visible at once. You can see the email box, the password box and the optional code box without scrolling, so nothing gets skipped by accident. On a phone the same form becomes a vertical stack, and the on-screen keyboard covers roughly the bottom half of the display the moment you tap into a field. Anything below the password box can sit out of view for the entire time you are typing.
That matters here because the code cannot be applied retroactively. If the package has not attached before you deposit, there is no later screen where you can paste RAKEBACK100 and recover the 250% match, the 60 free spins or the rakeback boost. The cost of a missed field on mobile is the whole offer, which is why the mobile sequence is worth treating as a deliberate process rather than three quick taps.
App versus mobile browser
Casino platforms are typically reached in one of two ways from a phone: through the mobile browser at the official web address, or through some form of installed shortcut or wrapper that sits on the home screen. The safest approach is to treat the official site opened in your browser as the reference point. That is where registration happens, and that is where you can read the URL in full before you type anything into a form.
If you use any installed route, the general rule is to confirm it leads to the same official domain. Home-screen icons hide the address bar by design, which is convenient for daily use and unhelpful the one time you need to verify where you are. A practical compromise: register in the browser with the address visible, confirm the package has attached, and only then save a shortcut for subsequent sessions.
Whichever route you take, the code field behaves the same way. Rainbet uses one input at registration for all three labels — affiliate, referral or promo. There is no separate mobile-only field and no second chance later in the flow, so you are looking for a single box however you arrive.
Where the field lives on a small screen
Optional fields are almost always placed last in a mobile form, and they are often collapsed behind a line of small text rather than shown as an open box. Things to look for once you have filled in your core details:
A short link or toggle worded along the lines of "have a code?" sitting below the password field
A collapsed section that expands into a text input when tapped
A label that reads affiliate, referral or promo — on Rainbet these all point at the same single field
A field that stays empty even after autofill has populated everything above it
Dismiss the keyboard before you scroll. On most phones you can tap outside the active field or use the keyboard's own close control. With the keyboard down you regain the lower half of the screen, and an optional code toggle that appeared to be absent frequently turns out to have been sitting just beneath it the whole time.
Mobile-only quirks worth knowing
Several small-screen behaviours can interfere with a code that is otherwise perfectly valid. None of them are unique to this platform; they apply to almost any mobile sign-up form.
Autocapitalisation. Mobile keyboards capitalise the first character of a field by default. RAKEBACK100 is upper case throughout, so this is usually harmless, but check the result rather than assuming.
Autocorrect. Keyboards sometimes try to "fix" unfamiliar strings or insert a trailing space. Read the field back character by character after typing.
Clipboard paste. Copying a code from a page or a message often carries an invisible space at either end. Paste, then check the cursor position at both ends before submitting.
Password managers. Autofill occasionally jumps focus between fields on smaller layouts, which can drop text into the wrong box. Verify the code sits in the code field and not in a name or email field.
Session interruptions. An incoming call, a notification or a switch between apps can reload a mobile page and clear a partially completed form. If you return to the form, re-check the code field before submitting.
Rotation. Turning the phone to landscape re-flows the layout and can move the optional section. If the field vanishes, rotate back rather than assuming it was never there.
A mobile-first sequence
Confirm that Rainbet operates in your jurisdiction. Roughly fourteen regions are excluded, among them the United States, the United Kingdom, Australia, the Netherlands and France.
Open the official site in your mobile browser and check the address before tapping into any field.
Begin registration and complete the core details first.
Dismiss the keyboard, scroll down, and expand the affiliate, referral or promo section — it is one field.
Type or paste RAKEBACK100, then read it back and remove any stray spaces.
Submit, and confirm the package has attached before you deposit. It cannot be applied afterwards.
If you are offered a choice between the wager-locked 250% track and a no-wager alternative, decide before depositing.
Deposit within the qualifying minimum and the per-deposit cap, and begin playing while the 72-hour rakeback window is live.
Read the free spin terms on their own. They carry separate rollover and expiry conditions from the deposit bonus.
Reading the terms on a phone
Terms pages are the least mobile-friendly part of any sign-up, and they are the part that decides what the package is actually worth. The deposit-bonus half carries a 40x wagering requirement, which means 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 rakeback half works differently. It returns a share of the house edge as cash with no rollover attached, which makes it smaller in headline terms and considerably easier to use. If you are reading only one section on a phone, read the section governing the 72-hour rakeback window, because that is the part you can realistically convert.
Use your browser's reader mode or text-size controls if the terms render in a very small font. Pinch-zooming a legal page on a phone encourages skimming, and skimming is how a 40x requirement gets mistaken for a gift.
Before and after the deposit
Two checks are worth building into the mobile routine. Before depositing, confirm on screen that the promotional package is showing as active on your account. After depositing, confirm the bonus and spins have credited as described rather than assuming the transaction implies both.
It is also worth deciding your deposit limit before you open the registration form, not while a countdown on the rakeback window is running. Mobile sessions are short, frequent and easy to repeat, which makes a number chosen in advance more useful than a number chosen in the moment. Rainbet is operated by RBGAMING N.V. under an Anjouan licence, and if a withdrawal is refused your escalation path runs through the operator and then a licensing body with limited enforcement capacity — another reason to settle the size of the deposit before the phone is in your hand.
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.
