Rainbet Referral Code RAKEBACK100 gives a new account a 250% deposit bonus up to $2,100, 60 free spins spread across the first three deposits, and a 20% rakeback boost for the first 72 hours of play. Most guides to this code describe the terms; this one deals with the practical problem of typing it in on a phone, where the registration form is compressed, the code field is often collapsed behind a link, and a mistyped or skipped entry cannot be fixed later.
Why the mobile route needs its own guide
Registration on a desktop screen usually shows every field at once, so an optional code box is hard to miss. On a phone the same form is stacked vertically, split across steps, or trimmed so that only the essentials — email, password, date of birth — are visible without scrolling. Optional inputs are the first thing a responsive layout hides.
That matters more here than it would on a shopping site, because Rainbet's code tracking is not retroactive. If you finish registration without RAKEBACK100 attached, support will not usually apply it afterwards, and opening a second account to correct the mistake breaches the one-account-per-person rule and risks confiscation. There is one chance to get the field right, and on mobile that chance is easier to scroll past.
App or mobile browser: what actually differs
Rainbet is a crypto casino and sportsbook operated by RBGAMING N.V. under an Anjouan gaming licence, with several thousand slot, live-casino and in-house titles alongside sports markets. Whichever surface you reach it through, the account you create is the same account and the code goes into the same tracking system.
The general trade-offs between a native app and a mobile browser are worth understanding before you choose:
A mobile browser gives you the full registration form as the operator publishes it, including any optional fields, and lets you zoom and inspect text before submitting.
A browser also makes it easy to confirm you are on the official domain rather than a lookalike, because the address bar is always visible.
Apps distributed outside official stores are installed manually, which means you are trusting the download source as well as the operator. Only ever install from a link on the official site.
Autofill and password managers behave more predictably in a browser, which reduces the chance of a stray value landing in the wrong box.
If a wrapped app simply loads the same site inside a frame, nothing about the code field changes — you are filling in the web form either way.
For a one-off task like attaching a referral code, the mobile browser is the lower-risk choice because you can see everything, including the URL. Once the account exists and the package is confirmed, the surface you play on is a matter of preference.
Where the code field hides on a small screen
On Rainbet there is a single input at registration that serves as the referral, promo and affiliate code field. Different articles call it different things, but it is one box and RAKEBACK100 belongs in it. Entering the code does two things at once: it attaches the promotional package to your account and it records which partner sent you.
Because it is one field with several names, the label you see on your phone may not match the word you searched for. Look for any of these patterns before you assume the field is absent:
A small link or toggle reading something like "have a code?", "referral code" or "optional" that expands an extra input when tapped.
An input that only appears after you scroll past the password confirmation, at the very bottom of the form above the submit button.
A second registration step that loads after the first, which is easy to rush through if the keyboard is covering the lower half of the screen.
A field pre-filled from a tracking link. If a code is already sitting there, check it reads RAKEBACK100 before submitting, and replace it if it does not.
If you cannot find the field at all, stop rather than submitting. Rotating the phone to landscape, dismissing the keyboard, or reloading the page often reveals a collapsed section that was sitting under the on-screen keyboard.
Mobile-only quirks that break code entry
Most failed code entries on phones are not the operator's fault. They come from how mobile keyboards and clipboards behave.
Auto-capitalisation and autocorrect can alter a code as you type it. RAKEBACK100 is all capitals with no spaces; if the keyboard inserts a space or suggests a different word, clear the field and retype it.
Copy and paste frequently carries a trailing space from wherever you copied it. Tap to the end of the field and check the cursor sits immediately after the final digit.
Predictive text bars can obscure the field you are typing into, so you may not see what actually landed there. Dismiss the keyboard and read the field back before moving on.
Switching apps mid-registration — to fetch a code from a message, for example — can reload the page and wipe the form. Copy the code first, then open the registration page once and stay in it.
Patchy mobile data can cause a submit to time out. Re-check that the account was actually created before trying again, rather than submitting twice.
Step by step on a phone
Confirm Rainbet accepts players from your jurisdiction. It operates in most markets outside the United States, and Ontario is excluded from its Canadian availability.
Copy RAKEBACK100, or memorise it, before you open the registration page.
Open the official Rainbet site in your mobile browser and start registration, keeping the address bar visible.
Scroll the whole form to the bottom and expand any collapsed optional section so you can see the referral, promo or affiliate code input.
Type or paste RAKEBACK100 into that field, then dismiss the keyboard and read it back character by character.
Complete registration, then open the promotions area of your account and confirm the package has attached before you do anything else.
If both options are offered in your region, choose your welcome track: the 250% wager-locked route or the lower-value no-wager alternative.
Deposit at or above the minimum qualifying amount and within the per-deposit cap.
Play inside the rakeback window — it runs on a clock and cannot be paused.
Claim the free spins separately and read their own expiry and rollover terms.
Checking the package attached, on a phone
The confirmation step is the one people skip on mobile, because the promotions area is usually behind a hamburger menu rather than a visible navigation bar. It is worth the extra taps. Referral and promotional terms vary by jurisdiction, and some regions see a different package or none at all — the code can attach where the offer itself does not apply. Checking what your account actually shows before you deposit is the only way to know which situation you are in.
Small screens also make it easy to skim past the terms attached to each half of the package, and the two halves are not comparable. The rakeback boost is credited as cash, accrues as you wager, and carries no rollover. The deposit bonus is credit locked behind a 40x wagering requirement, an RTP ceiling and a max-bet cap — a $700 bonus needs $28,000 in qualifying wagers before any of it converts, which is forty times the bonus amount. Read the full terms on a larger screen if you can; if you cannot, zoom in rather than assuming.
Deposits and the clock on mobile
Rainbet supports both crypto and card or e-wallet payments, and the payment step is where mobile adds friction rather than features. Crypto deposits on a phone typically involve switching to a wallet app and back, and each switch is a chance to leave the browser page and lose your place. Card and e-wallet payments may bounce you through an authentication screen controlled by your bank. Neither is unusual, but both take longer than the desktop equivalent, and the rakeback boost runs on a 72-hour clock from the point it starts.
The practical consequence is to do your setup before the clock matters: register, confirm the package, and have your payment method ready and working in the browser you intend to use. A boost measured in hours is worth less if a chunk of those hours goes on troubleshooting a wallet handoff.
Generating your own code from a phone
If you later want to refer others, your own code is created from the affiliates section of your account, which on mobile sits inside the account menu rather than on the main screen. Enrolling makes you a partner rather than a casual referrer: you get a dashboard, tracking links and a payout wallet, and you also take on the programme's terms, including its excluded-market list.
Understand what that means before you share a link. Rainbet does not pay a flat finder's fee; partners receive an ongoing share of the net revenue the operator earns from referred play, quoted from 25% up to 60%, with cost-per-acquisition and hybrid deals negotiated individually, plus a sub-affiliate layer. Under revenue share, that income rises when referred players lose over time. A tracking link is quick to send from a phone, which is exactly why it deserves a moment's thought first.
The short version
Use a mobile browser rather than a sideloaded app for registration, scroll the entire form before submitting, expand any collapsed optional section, and read the code back after typing it. Entering RAKEBACK100 costs nothing and gives you more than registering bare, and the rakeback boost — cash, no rollover — is the part of the package with the fewest strings. The one thing a phone cannot fix is a code left out, so slow down for that single field and check the promotions area before any money moves.
