Gamdom Referral Code CBG60 gives new players a 15% rakeback boost plus 50 free spins when it is entered at registration, and the code works exactly the same whether you sign up on a desktop machine or on a phone. What changes on a small screen is not the offer but the plumbing around it: where the code field sits, how easy it is to miss, and how likely your keyboard or clipboard is to sabotage the entry. This guide is written for people registering on mobile.
Why mobile registration deserves its own walkthrough
A referral code links a new account to whoever shared it. You receive the package attached to the code, and the referrer receives a share of the platform's revenue from your play on an ongoing basis. That arrangement is normal and disclosed across the online casino sector, but it only pays out for either side if the code actually attaches to your account at the moment you register.
On desktop, a registration form usually shows every field at once, so an optional code box is hard to overlook. On a phone the same form is stacked vertically, the on-screen keyboard covers the lower half of the display, and optional fields are frequently collapsed behind a link or a small toggle. The single most common way to end up without the offer on mobile is simply scrolling past the field and tapping the submit button because it was the next thing visible.
Where the code field lives on smaller screens
The field you are looking for may be labelled referral, promo or bonus code. All three labels refer to the same input, so do not keep scrolling in search of the exact word you were told to expect. On narrow layouts this input typically appears in one of a few places:
Directly beneath the password or email fields, as the last item before the terms checkbox.
Behind a small text link such as "have a code?" that expands the field when tapped.
Inside a second step of the form, after you have supplied your basic details but before the account is created.
Hidden under the keyboard, visible only after you dismiss it by tapping outside the input or using the keyboard's close control.
Before you submit anything, dismiss the keyboard and scroll the form from top to bottom once. If you cannot see a code field at all, look for any collapsed or greyed-out section. Registering first and hunting for the field afterwards is the one order of operations that does not work, because referral codes are generally registration-time only.
App versus mobile browser
Whichever route you take, the registration must happen on the official Gamdom site or an official Gamdom channel. If you are considering an app, find the link from the official site itself rather than from a search result, a forum post or a message, and treat any download offered elsewhere as suspect. Unofficial wrappers around casino sites exist and they are a poor place to type an email address and a password.
In practice a mobile browser has a few advantages for the registration step specifically:
You can see the full address of the page you are on, which an in-app view may hide.
Password managers and autofill behave more predictably.
If a form misbehaves you can request the desktop version of the page, which often restores the wider layout and makes the code field obvious.
Zooming in to check the characters you have typed is easier.
The trade-off is that browsers on mobile are more likely to discard a half-completed form if you switch away to another tab or another app to copy the code. Decide where the code is coming from before you open the registration form.
Typing CBG60 rather than pasting it
Formatting is a known reason for a code being rejected, and a trailing space copied along with the code is a common cause. Mobile clipboards make this worse, because tapping and dragging to select five characters inside a block of text frequently grabs a space, a line break or a stray punctuation mark at the edge of the selection.
The code is five characters long. Type CBG60 manually. While you do, watch for two mobile-specific keyboard behaviours: autocorrect trying to convert the string into a word, and the automatic capitalisation setting fighting you when you switch between letters and the numeral. After typing, tap elsewhere to dismiss the keyboard and read the field back before continuing. If the field shows anything other than the five characters, clear it fully rather than backspacing part of it.
The registration sequence on a phone
Open the official Gamdom site in your mobile browser, or an official app obtained from a link on that site.
Start the registration form and scroll it once from top to bottom so you know where every field is, including any collapsed section.
Fill in your account details, then locate the referral, promo or bonus code field.
Type CBG60 into that field manually and read it back with the keyboard dismissed.
Complete registration and confirm that the code has attached to your account.
Leave the rakeback boost inactive until you are actually ready to play, because the window runs from activation rather than registration.
Deposit and play through the boost period.
Claim the 50 free spins separately and read their terms when they credit.
Mobile-only quirks worth planning around
The rakeback boost runs for an initial window of typically seven days from activation, and that window is easy to waste through poor timing. Phones invite short, scattered sessions, which is the opposite of what this mechanism rewards. Rakeback returns a share of the house edge your wagering generates rather than a share of the wagers themselves: on a game with a 4% edge, $1,000 of wagering generates around $40 of edge, and a 15% rate returns roughly $6 of that. A 15% rate also means 85% of that edge is not returned, which is the part the marketing around these codes tends to leave out.
So the boost is worth a great deal to someone playing high volume in their first week and very little to someone placing a few bets between other things. That is the mechanism, not a defect. If your play is mobile and casual by nature, the honest planning assumption is that the rakeback element will be small, and the 50 free spins will be the more tangible half of the package for you.
Two other differences matter on a handset. Rakeback carries no wagering requirement, so what it returns is immediately yours and cannot be forfeited by a mistimed session. The free spins behave more like a conventional casino bonus: winnings usually carry a rollover requirement and the spins carry an expiry window. Reading full bonus terms on a phone is genuinely unpleasant, so do it once, properly, at the moment they credit rather than in the middle of a session.
If the code will not attach
A handful of causes cover almost every failure, and none of them are fixed by trying again harder:
Entered after registration. Codes are generally registration-time only and cannot be applied to an existing account. Contact support before you deposit if you missed the field.
Already linked to another referrer. An account can only carry one referral relationship.
Regional restriction. Promotional availability varies by country and some markets are excluded entirely.
Formatting. Clear the field and type the five characters again by hand.
After the boost window closes
Beyond the signup offer, the platform carries over 7,000 titles from established providers alongside provably fair in-house originals, plus a sportsbook, and a community layer of chat, rain events and giveaways that is more prominent than on most casinos. The Royalty Club runs 24 levels across eight tiers from Bronze to Opal, with baseline rakeback rising toward an advertised 60% at the top. That ceiling requires volume well beyond recreational play, and a new account starts at the bottom of the ladder, so plan around the initial boost rather than the headline maximum.
If you are registering anyway, entering CBG60 on mobile gets you more than registering without it, and the lack of a rollover on the rakeback portion makes it a cleaner structure than most deposit bonuses in this sector. Judge it on the mechanism, activate the boost when you will actually play, and set a spending limit before you deposit rather than during a session.
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.
